• Need help to install Ubuntu on Win7 Alienware M17xR3, installing not working

  - by Rodrigo

  Please I need help to install linux on my computer to start analyzing Next Generation Sequencing (molecular genetics) for my work. I've tried to install from all different ways and forms and it gave me different errors. First I will describe my system: Alienware M17x R3 Raid Drive 596GB (2x 298 GB) Windows7 primary partition C: The hardrive is divided in 3 primary partitions (can't do 4 don't know why) 1st: Fat16 no name capacity 40mbs almost not used (has files like command.com, dellbio.bin, dellrmk.bin and oobedone.flg) I dont know what this is for but is blocked and non system (Status:none). 2nd: Recovery NTFS 9GB (Status:system) and it seems to have boot files. 3rd: CD: Windos OS (status:boot). And I have 2 Logical drivers F: data for backup and games :D (300gb) G: For trying to install the Linux (Already tried with Fat32, Ext2, ext3 and ext4) Installing with Wubi on F: and G: Instalation looks good on windows ask to restart dos mode appears: try (HD0,0) non-ms:skip try (HD0,1) NTFS5: No Wibildr try (HD0,2) NTFS5: Error: "Prefix" is not set. Installing with Wubi on C: Installation looks good on windows ask to restart dos mode apears: Mount denied becouse NTFS volume is already exclusive opened, the volume may be already mounted or another software may use it which could be identified for example by the help of the 'FUSER' command Mount devdm-4 Could not find installation files /ubuntu/install custom-installation Run 'Chkdsk /r' on windows and restart...blablablalba... that should correct. done this didn't work. Tried installing with USB drive and after burning a CD with the Iso file download from the official website: I've tried the option to install along windows with a G: drive in FAT32, EXT2,3 and 4, I've tried to leave unallocated data, without the driver G at all... appears this everytime: http://i.stack.imgur.com/eo2Ie.png pres ok it ask me to: Not possible to install the boot loader at the location: specify new location: I've tried to select all the drivers non is accepted If I ask to continue without installing the boot loader he ask me to install later by myself which I'm trying to figure it out but I'm not really good to understand how ppl get to the programming part like a DOS to write down couse I'm a newb and I've dont work on dos or linux before... I've read that the boot loader has to be installed on the primary partition, but I'm not sure what I can delete from those 2 partitions that would let me get 1 extra... and it seems that the one that windows use is protected to write down so the software is not touching it... Please if someone have any idea to help me out... I've got a course tomorrow of how to use the software to analyze the data and I wanted to take my computer with me, so I've passed the last 3 days trying to search different ways to solve. My question is also post on the bugs.launchpad.net link here: lounchpad.net bug #882695

  - by Fox Mulder

  I have a multi lan port box that install ubuntu server 11.10. I am setup network in /etc/network/interfaces file as follow: auto lo iface lo inet loopback auto eth0 iface eth0 inet static      address 192.168.128.254      netmask 255.255.255.0      network 192.168.128.0      broadcast 192.168.128.255      gateway 192.168.128.1      dns-nameservers xxxxxx auto eth1 iface eth1 inet static      address 192.168.11.1      netmask 255.255.255.0      network 192.168.11.0      broadcast 192.168.11.255 auto eth2 iface eth2 inet static      address 192.168.21.1      netmask 255.255.255.0      network 192.168.21.0      broadcast 192.168.21.255 auto eth3 iface eth3 inet static      address 192.168.31.1      netmask 255.255.255.0      network 192.168.31.0      broadcast 192.168.31.255 I am also enable the ip forward by echo 1 /proc/sys/net/ipv4/if_forward in rc.local. my dnsmasq config as follow except-interface=eth0 dhcp-range=interface:eth1,set:wifi,192.168.11.101,192.168.11.200,255.255.255.0 dhcp-range=interface:eth2,set:kids,192.168.21.101,192.168.21.200,255.255.255.0 dhcp-range=interface:eth3,set:game,192.168.31.101,192.168.31.200,255.255.255.0 the dhcp was working fine in eth1,eth2,eth3, any machine plug in the subnet can get correct subnet's ip. My problem was, each subnet machine can't ping each other. for example. 192.168.11.101 can't ping 192.168.21.101 but can ping 192.168.128.1 192.168.31.101 can't ping 192.168.21.101 but can ping 192.168.128.1 I am also try to using route add -net 192.168.11.0 netmask 255.255.255.0 gw 192.168.11.1 (and also 192.168.21.0/192.168.31.0) at this multi-lan-port machine. But still won't work. Does anyone can help ? Thanks.

  I have downloaded a Xen virtual machine image from the appscale project, and I am trying to start it up. However once I run the command; xm create -c -f xen.conf The instance immediately crashes and provides no console output. however it produces logs that I have posted below. but this is the error; [2011-03-01 12:34:03 xend.XendDomainInfo 3580] WARNING (XendDomainInfo:1178) Domain has crashed: name=appscale-1.4b id=10.

• Assign fixed IP address via DHCP by DNS lookup

  - by Janoszen

  Preface I'm building a virtualization environment with Ubuntu 14.04 and LXC. I don't want to write my own template since the upgrade from 12.04 to 14.04 has shown that backwards compatibility is not guaranteed. Therefore I'm deploying my virtual machines via lxc-create, using the default Ubuntu template. The DNS for the servers is provided by Amazon Route 53, so no local DNS server is needed. I also use Puppet to configure my servers, so I want to keep the manual effort on the deployment minimal. Now, the default Ubuntu template assigns IP addresses via DHCP. Therefore, I need a local DHCP server to assign IP addresses to the nodes, so I can SSH into them and get Puppet running. Since Puppet requires a proper DNS setup, assigning temporary IP addresses is not an option, the client needs to get the right hostname and IP address from the start. Question What DHCP server do I use and how do I get it to assign the IP address based only on the host-name DHCP option by performing a DNS lookup on that very host name? What I've tried I tried to make it work using the ISC DHCP server, however, the manual clearly states: Please be aware that only the dhcp-client-identifier option and the hardware address can be used to match a host declaration, or the host-identifier option parameter for DHCPv6 servers. For example, it is not possible to match a host declaration to a host-name option. This is because the host-name option cannot be guaranteed to be unique for any given client, whereas both the hardware address and dhcp-client-identifier option are at least theoretically guaranteed to be unique to a given client. I also tried to create a class that matches the hostname like this: class "my-client-name" { match if option host-name = "my-client-name"; fixed-address my-client-name.my-domain.com; } Unfortunately the fixed-address option is not allowed in class statements. I can replace it with a 1-size pool, which works as expected: subnet 10.103.0.0 netmask 255.255.0.0 { option routers 10.103.1.1; class "my-client-name" { match if option host-name = "my-client-name"; } pool { allow members of "my-client-name"; range 10.103.1.2 10.103.1.2; } } However, this would require me to administer the IP addresses in two places (Amazon Route53 and the DHCP server), which I would prefer not to do. About security Since this is only used in the bootstrapping phase on an internal network and is then replaced by a static network configuration by Puppet, this shouldn't be an issue from a security standpoint. I am, however, aware that the virtual machine bootstraps with "ubuntu:ubuntu" credentials, which I intend to fix once this is running.

• Apache cannot find mysql database modules

  - by user809857

  I've created a simple django project and setup a mysql database. My simple project just creates an entry on the database. The project works fine when I use the built in development server provided by django (runserver) and it works well. But when I deployed the project on Apache and mod_Wsgi (Ubuntu server), django could not find 'books', which is in this case my table in the database. The mysql database that I use in runserver and apache are just the same. I also did rebuild the database using sqlall,validate and syncdb of django but still i get the error. What could be wrong with what I'm doing? Thanks

• 4 Alternatives to Google Drive for Linux

  - by Chris Hoffman

  We’ve covered using Google Drive on Linux with third-party software, but why bother jumping through those hoops? You can use a cloud storage service that officially supports Linux instead – several of Google Drive’s competitors do. Google may be leaving Linux users out, but other services like Dropbox, Ubuntu One, SpiderOak, and Wuala don’t ignore Linux users. They even offer more storage and other useful features, such as local encryption of your files.

  - by Sid

  I'm trying to get a stream off port 9999 and write to /dev/xvdf. I'm using Amazon EC2 with the Ubuntu 11.10 server image. By default I log in as 'ubuntu' which has sudo privileges. However, when I run the following netcat command, I get this error ubuntu@ip-10-252-35-122:~$ ls -al /dev/xv* brw-rw---- 1 root disk 202, 1 2011-11-30 22:22 /dev/xvda1 brw-rw---- 1 root disk 202, 80 2011-11-30 22:27 /dev/xvdf ubuntu@ip-10-252-35-122:~$ sudo netcat -p 9999 -l > /dev/xvdf bash: /dev/xvdf: Permission denied ubuntu@ip-10-252-35-122:~$ Any idea why I get the permission denied error and how I can work around it? Update: Something mysterious is running in the background that resets the permissions?

• Is it OK to remove appmenu-gtk and install appmenu-gtk:i386?

  - by medigeek

  I wanted to eliminate some skype errors and by installing the appmenu-gtk:i386 package the errors were gone! $ skype /usr/lib/gtk-2.0/2.10.0/menuproxies/libappmenu.so: wrong ELF class: ELFCLASS64 (skype:2841): Gtk-WARNING **: Failed to load type module: /usr/lib/gtk-2.0/2.10.0/menuproxies/libappmenu.so /usr/lib/gtk-2.0/2.10.0/menuproxies/libappmenu.so: wrong ELF class: ELFCLASS64 (skype:2841): Gtk-WARNING **: Failed to load type module: /usr/lib/gtk-2.0/2.10.0/menuproxies/libappmenu.so /usr/lib/gtk-2.0/2.10.0/menuproxies/libappmenu.so: wrong ELF class: ELFCLASS64 (skype:2841): Gtk-WARNING **: Failed to load type module: /usr/lib/gtk-2.0/2.10.0/menuproxies/libappmenu.so /usr/lib/gtk-2.0/2.10.0/menuproxies/libappmenu.so: wrong ELF class: ELFCLASS64 (skype:2841): Gtk-WARNING **: Failed to load type module: /usr/lib/gtk-2.0/2.10.0/menuproxies/libappmenu.so The change was easy: sudo apt-get install appmenu-gtk:i386 I haven't noticed any "weird" outcome (yet). The good thing was that it cleared the skype errors. But I have my doubts. Has anyone tried something similar? Removing appmenu-gtk and installing appmenu-gtk:i386 on a 64-bit system? Could it break any applications? Similar question: Resolving dependencies related to 32 bit libraries on 64 bit

• Did 12.04 just add multi-touch gesture support mid-release?

  - by adempewolff

  I was reviewing the updates I was about to download today and I noticed that a lot of them had to do with gesture support, noticed that many of these were new installs rather than upgrades. Has 12.04 just added multi-touch gesture support mid-release? If so, what are the capabilities that this adds? Which applications already support these capabilities and can I expect others to add support in the near future? Here are the packages that were installed: Install: libframe6:amd64 (2.2.4-0ubuntu0.12.04.1), libgeis1:amd64 (2.2.9.2-0ubuntu1), libgrail5:amd64 (3.0.6-0ubuntu0.12.04.01, automatic) And here are those that were upgraded (also including many with touch support): Upgrade: libgrip0:amd64 (0.3.4-0ubuntu2~ubuntu12.04.1, 0.3.5-0ubuntu1~12.04.1), eog:amd64 (3.4.2-0ubuntu1, 3.4.2-0ubuntu1.1), ginn:amd64 (0.2.4-0ubuntu1, 0.2.4.1-0ubuntu1) Of which the descriptions for the new installs are, libgeis1: Gesture engine interface support A common API for clients of a systemwide gesture recognition and propagation engine. libframe6: Touch Frame Library This library handles the buildup and synchronization of a set of simultaneous touches. The library is input agnostic, with bindings for mtdev, frame and XI2.1. libgrail5: Gesture Recognition And Instantiation Library This library consists of an interface and tools for handling gesture recognition and gesture instantiation. Applications can use the grail callbacks to receive gesture primitives and raw input events from the underlying kernel device. And the descriptions for the upgraded packages are, ligrip0: provides multitouch gestures to GTK+ apps Libgrip hooks gesture recognition into GTK+ applications. ginn: Gesture Injector: No-GEIS, No-Toolkits A daemon with jinn-like wish-granting capabilities: it gives applications the ability to support a subset of multi-touch gestures without having to integrate GEIS or multi-touch GTK/Qt libs. Adding in a ton of new libraries and upgrading the existing components makes me wonder if 12.04 is meant to start natively supporting gestures other than two finger scroll in the near future. I expected these capabilities to be introduced soon but I thought that they would only be rolled out in a new release, not as upgrades for an existing release. Anyone have any info about this?

• How to solve 404 for static files with Django and Nginx?

  - by Lucio

  I setup a Trusty VM with Django + Nginx (other stuffs too). The server is working, I get the "Welcome to Django" page. But when I enter to servername/admin it loads the HTML page but fails to load the static content. And the admin page have this links to static content: <link rel="stylesheet" type="text/css" href="/static/admin/css/base.css" /> <link rel="stylesheet" type="text/css" href="/static/admin/css/login.css" /> Both of the CSS files give me 404, as the Nginx log shows: 192.168.56.1 - - [05/Jun/2014:12:04:09 -0300] "GET /admin HTTP/1.1" 301 5 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:29.0) Gecko/20100101 Firefox/29.0" 192.168.56.1 - - [05/Jun/2014:12:04:09 -0300] "GET /admin/ HTTP/1.1" 200 833 "-" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:29.0) Gecko/20100101 Firefox/29.0" 192.168.56.1 - - [05/Jun/2014:12:04:10 -0300] "GET /static/admin/css/base.css HTTP/1.1" 404 142 "http://ubuntu-server/admin/" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:29.0) Gecko/20100101 Firefox/29.0" 192.168.56.1 - - [05/Jun/2014:12:04:10 -0300] "GET /static/admin/css/login.css HTTP/1.1" 404 142 "http://ubuntu-server/admin/" "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:29.0) Gecko/20100101 Firefox/29.0" I think that the error is on my nginx.conf file, but do not know how to solve it.

• How to Back Up Your Linux System With Back In Time

  - by Chris Hoffman

  Ubuntu includes Déjà Dup, an integrated backup tool, but some people prefer Back In Time instead. Back In Time has several advantages over Déjà Dup, including a less-opaque backup format, integrated backup file browser, and more configurability. Déjà Dup still has a few advantages, notably its optional encryption and simpler interface, but Back In Time gives Déjà Dup a run for its money.

• ruby on rails gitorious setup on ubuntu

  - by dogmatic69

  Ive been trying to install gitorious for a while now which required ruby and rails etc. Ive finally got rails pages serving but cant finish the installation of gitorious because the gem version is too new. the error logs say please run 'rake ultrasphinx:configure' and that gives rake ultrasphinx:configure (in /var/www/apps/gitorious) rake aborted! uninitialized constant ActiveSupport::Dependencies::Mutex /var/www/apps/gitorious/Rakefile:10:in `require' (See full trace by running task with --trace) From searching google this is beacuse of the wrong gem verison. Cant find a way to down grade it. apparently sudo gem update --system 1.4.2 should do the trick but ubuntu 10.10 does not like this. ERROR: While executing gem ... (RuntimeError) gem update --system is disabled on Debian, because it will overwrite the content of the rubygems Debian package, and might break your Debian system in subtle ways. The Debian-supported way to update rubygems is through apt-get, using Debian official repositories. If you really know what you are doing, you can still update rubygems by setting the REALLY_GEM_UPDATE_SYSTEM environment variable, but please remember that this is completely unsupported by Debian. So i added export REALLY_GEM_UPDATE_SYSTEM=1 to .bashrc and reloaded it with . ~/.bashrc and still the same. ive tried various forms of setting this environmental variable with no luck. Ive also been told on #gitorious irc channel to add the file config/initializers/rubygems.rb with the line require "thread" to it. This has done nothing. EDIT: Just found another way which was rvm install rubygems 1.4.2 and it gave: Removing old Rubygems files... Installing rubygems dedicated to ruby-1.8.7-p334...

• In Linux how do I mount a OS-X partition * by name * that is on the same host?

  - by philcolbourn

  I once used gnome-mount like this gnome-mount -o ro -d /dev/sda2 or gnome-mount -o ro -p "Macintosh HD" But, alas, gnome-mount seems to be no more. RIP. I can do this gvfs-mount -d /dev/sda2 (which generates a whole lot of errors but does mount the partition in the /media directory.) This is a related question: http://superuser.com/questions/131918/gnome-mount-alternative-in-ubuntu-10-04-or-how-to-mount-partition-with-normal-use But how do you do it by name?

• How can I make my binary file is served as binary, not text when user choose "Save Linked File As..." in Safari?

  - by Eonil

  I'm serving a binary file (.IPA) with Ubuntu/Apache 2.2. When I have chosen Save Linked File As... in Safari, it says it's text file. And it guides me to add .txt extension. However it does not add any extra extension when I download it just clicking link. I added line AddType application/octet-stream .ipa in apache configuration file. I don't know what's wrong with this. Is this a bug of Safari or my misconfiguration? (1) If it caused by bug, how can I avoid this? (2) Or if it caused by misconfiguration, what should I do?

• Assign fixed IP address via DHCP by DNS lookup

  - by Janoszen

  Preface I'm building a virtualization environment with Ubuntu 14.04 and LXC. I don't want to write my own template since the upgrade from 12.04 to 14.04 has shown that backwards compatibility is not guaranteed. Therefore I'm deploying my virtual machines via lxc-create, using the default Ubuntu template. The DNS for the servers is provided by Amazon Route 53, so no local DNS server is needed. I also use Puppet to configure my servers, so I want to keep the manual effort on the deployment minimal. Now, the default Ubuntu template assigns IP addresses via DHCP. Therefore, I need a local DHCP server to assign IP addresses to the nodes, so I can SSH into them and get Puppet running. Since Puppet requires a proper DNS setup, assigning temporary IP addresses is not an option, the client needs to get the right hostname and IP address from the start. Question What DHCP server do I use and how do I get it to assign the IP address based only on the host-name DHCP option by performing a DNS lookup on that very host name? What I've tried I tried to make it work using the ISC DHCP server, however, the manual clearly states: Please be aware that only the dhcp-client-identifier option and the hardware address can be used to match a host declaration, or the host-identifier option parameter for DHCPv6 servers. For example, it is not possible to match a host declaration to a host-name option. This is because the host-name option cannot be guaranteed to be unique for any given client, whereas both the hardware address and dhcp-client-identifier option are at least theoretically guaranteed to be unique to a given client. I also tried to create a class that matches the hostname like this: class "my-client-name" { match if option host-name = "my-client-name"; fixed-address my-client-name.my-domain.com; } Unfortunately the fixed-address option is not allowed in class statements. I can replace it with a 1-size pool, which works as expected: subnet 10.103.0.0 netmask 255.255.0.0 { option routers 10.103.1.1; class "my-client-name" { match if option host-name = "my-client-name"; } pool { allow members of "my-client-name"; range 10.103.1.2 10.103.1.2; } } However, this would require me to administer the IP addresses in two places (Amazon Route53 and the DHCP server), which I would prefer not to do. About security Since this is only used in the bootstrapping phase on an internal network and is then replaced by a static network configuration by Puppet, this shouldn't be an issue from a security standpoint. I am, however, aware that the virtual machine bootstraps with "ubuntu:ubuntu" credentials, which I intend to fix once this is running.
