  • Updating Python on Ubuntu system

    - by efficiencyIsBliss
    I want to update the Python build on my Linux box, but the only way I know how to do it is uninstalling the current version and installing the new one. My system is already up to date (I updated yesterday). I wanted to know if there is a way to update a specific program from the command line, like sudo apt-get update <program-name>. I know this command doesn't exist, but I'm hoping something equivalent does.

  • Is Ubuntu 10.04 suitable for working on for web development

    - by wombart
    Hi everyone, Im just wondering what everyone's experiences are with the latest Ubuntu 10.04 version? Is it stable enough for a working environment? I require it for web development, so using VMs, IDEs, connecting to VPNs, SSH to servers, etc. Im currently using 9.04 and found 9.10 unstable and problematic at times (such as problems connecting to VPN) Any input would be appreciated, thanks!

  • Ubuntu server users question

    - by Camran
    I have read this article: https://help.ubuntu.com/9.04/serverguide/C/user-management.html But it doesn't go into depth with the privileges section. I need to know how to set privileges of me (as a user). I am the only user, but I want access to everything, but I don't want to manage my VPS logged in as root. So I am creating a username. Anybody have a list of privileges, what they mean and how to set them? Thanks

    - by greggannicott
    Hi. I've just made the switch to Ubuntu on my main PC and I've been looking for a media player that can: Play all the usual video formats Rate (and ideally, tag) each file Display thumbnails for each file Other than that there isn't much I'm after. Banshee comes close, but doesn't display thumbnails. I've Google'd lots but I'm running out of search terms to try. Does anyone have any suggestions? Cheers!

  • local host gives error 403 on Ubuntu

    - by Dan
    Hello I am new to ubuntu linux and am currently trying to configure my netbeans to work with PHP. I have found several tutorials to install all the applications I need and have installed a virtual directory for netbeans to run in. Unfortunately, whenever netbeans or I myself go to my local host I get an error 403. I tried modifying my settings to allow from localhost (instead of allow from all) but this did not work and am completely out of ideas.

  • How to version lock packages in Ubuntu?

    - by Sandra
    On CentOS exists the yum versionlock option, where you can lock a package to a specific version, so it is never upgraded past that. I would like that puppet-server-2.7.19-1 puppet-2.7.19-1 stays on 2.7, and never upgraded to 3.0. Puppet Labs have released 3.0 and put it into the stable repo, so 2.7 will get upgraded to 3.0, which is not backwards compatible. Does Ubuntu have something similar to yum versionlock?

  • Apache on Ubuntu very slow on inital calls, very fast afterwards

    - by papakost
    I own an Ubuntu 10 VPS Server with Apache 2 hosting a Magento website. The first hit to the site from any client takes about 15-20 sec, while the subsequent hits from the same client take 0-1 sec. I suppose it doesn't have to do with Magento caching, because this happens also when the first call is on a very light page and the next calls are on heavy ones. Does anyone have an idea on what is going wrong here?

  • Ubuntu 9.10 Server (minimal virtual machine) partitioning

    - by John
    I am setting up a generic Ubuntu server and am trying to figure out the (best) way to partition the machine. Again, this is just a generic one: The default drive is 20GB. Some guides show: Separate /home, /usr, /var and /tmp partitions Another one suggested something like this: / 4GB /boot 512MB /tmp 1GB /home 5GB /usr 5GB /var 5GB What is the best way to accomplish this?

  • All tweak settings not saving after last 2 updates?

    - by mawburn
    I am running Ubuntu GNOME 14.04. After the last 2 updates, all settings in the Tweak menu are no saving. It will also not switch to the Gnome Dark theme at all. This includes all Startup Application changes as well as any changes to Extension settings. I'm not sure if I need to include any sort of log records or anything like that, so if you need any more information please ask. I've noticed the default fonts seem to be different. I don't remember that being part of the theme settings. It's almost like I'm running in Safe Mode.

  • Problems in creating click package for native application

    - by Swordfish90
    Hello everyone I've tried may times to package a native click application mainly following this tutorial: http://notyetthere.org/?p=316 The procedure works and I'm able to execute the binaries both on phones and desktops. The problems start when I install the click package. The application is launched but the game is not working (the "gamefield" is not loaded). The only error message that is given is that versions of localstorages are not compatible (that is impossbile, because it never changed). I suspect that the problem is related to apparmor but I have no proof of that. The source code of the application is available here: https://launchpad.net/ubuntu-netwalk Thank you in advance to everyone...

  • Ubuntu server random hangups.

    - by Ebbe
    Hello all. this is my first post to this forum which I found through the superb podcast "It Conversations" from StackOverFlow. I am quite in my role as server administrator for an exhibition center in London. Basically we have a central file and sql server to which roughly 40 stations connects to to upload/download data used/captured by a set of applications. Over the last weeks we have experienced a few random hangups to our applications, and as it always happen to multiple applications simultaneously I do not believe that the applications are the source of the problem. We also monitor the network using Dartware Intermapper which indicates that all switches and stations on the network has been reachable during the downtime. Thus, its all pointing to the server. I have been looking through all log files I can think of and the only thing so far that I have found suspicious is the following lines in the syslog which are from the time of one of the hangups: Feb 6 17:14:27 es named[5582]: client 127.0.0.1#33721: RFC 1918 response from Internet for 150.0.168.192.in-addr.arpa Feb 6 17:14:40 es named[5582]: client 127.0.0.1#32899: RFC 1918 response from Internet for 152.0.168.192.in-addr.arpa Feb 6 17:15:01 es /USR/SBIN/CRON[1956]: (es) CMD (/home/es/apps/es/bin/es_checksum.sh) Feb 6 17:16:06 es /USR/SBIN/CRON[2031]: (es) CMD (/home/es/apps/es/bin/es_checksum.sh) Feb 6 17:21:00 es named[5582]: *** POKED TIMER *** Feb 6 17:21:00 es last message repeated 2 times Feb 6 17:21:07 es named[5582]: client 127.0.0.1#44194: RFC 1918 response from Internet for 143.0.168.192.in-addr.arpa Feb 6 17:21:12 es named[5582]: client 127.0.0.1#59004: RFC 1918 response from Internet for 164.0.168.192.in-addr.arpa I find a few lines of interesting lines here: 1) "RFC 1918 response from Internet for 150.1.168.192.in-addr.arpa". I see this a lot in the syslog. And basically everytime I do a nslookup for any of the computers in the cluster I get a new similar line in the syslog. I understand from google that this has to do with reverse lookup problems. But I do not know how that could effect the systems. Lets say that one of these lines appear every time one of the userstations connects to the server, which may happen several times a second. Could this possible cause a hangup of the entire server? 2) POKED TIMER, I have googled this quite a lot, but not found an explaination that I can relate to. What does this mean? 3) The timestamps, it seems like the entire server has stopped responding for several minutes. Normally there are many printouts to the syslog per minute on this server. Furthermore the CRON job is set to run once every minute. Which according to the log, hasent happened here. OS: Ubuntu 8.04 Kernel: Linux 2.6.24-24-server x86_64 GNU/Linux. Hardware: Dell R710, RAID1, CPU: 2x XEON E5530. 16GB Memory. Average load is very low, and memory should not be a problem. Please let me know if you need any additional information. Best wishes, Ebbe

  • Ubuntu 8.04 server is not retaining a static IP address

    - by James Pierce
    I recently setup a linux box running Ubuntu 8.04 (to match another server with 8.04). I need to insure that this box has a static IP address and I changed /etc/network/interfaces to set up the static IP address and when I run sudo /etc/init.d/networking restart it works fine for a while, but always reverts back to 10.0.1.24 after being idle for a while. I also tried stopping/removing the dhcp client, but that didn't help. sudo /etc/init.d/dhcp stop sudo apt-get remove dhcp3-client Here is my /etc/init.d/networking: # The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet static address 10.0.1.4 netmask 255.255.255.0 broadcast 10.0.1.255 gateway 10.0.1.1 Any thoughts? Thanks.

  • Double default gateway ubuntu server

    - by Elena
    Hi, I've just installed an Ubuntu server 9.10 on an EEEBox. This is my /etc/network/interfaces # The loopback network interface auto lo iface lo inet loopback auto wlan0 iface wlan0 inet static address 192.168.48.16 netmask 255.255.248.0 wireless-essid mynet auto eth0 iface eth0 inet static address xx.xx.xx.xx netmask 255.255.255.224 gateway xx.xx.yy.yy When I restart /etc/init.d/networking, I can access the eth0 ip address from the internet and I can ping the machines in my wifi network mynet. Everything works fine and I have one default gateway. But after some time if I check again the route I just find two default gateways: one is correct and is the previous one, but the other is the one of the wifi network. I have a quite low signal of mynet where my server is and sometimes the wifi just disconnect and then reconnect again. Then I think that this can be a problem and the dhcp of the wifi net, when reconnecting it also add a default gateway. Any idea on how to resolve this issue?

  • Running out of LowMem with Ubuntu PAE Kernel and 32GB of RAM

  • go back to original version of firefox in ubuntu from beta version

    - by Jack Coroman
    In ubuntu 9.04, I tried to upgrade from firefox 3.0 to 3.5, by installing some apt-get packages, and there is a problem! Now firefox calls itself "Namoroka" and the firefox logo is gone and replaced by a black square in the upper bar and it says it is a development beta version. I really don't like this version, how can I go back to the stable version of firefox? I tried apt-get remove firefox-3.5 and apt-get install firefox-3.0 and that did not work. How do I go back to the stable version of firefox?
