• Compiling old versions of R (2.11 or older) on Ubuntu 13.10 (or newer)?

  - by user283293

  I am trying to compile an old version of R (2.11.1, specifically). "Why?", you might ask. Well, I have a program I am trying to run (that was not written by me, but I am hoping to use in my research) that was written in "old" R, and the program writer has specifically mentioned that R-2.11.1 or older must be used. I have run ./configure with no obvious errors (the entire output being far too long to post here, but I have been warned that I cannot make PDF, DVI, or HTML versions of the help pages, which I'm not too concerned about). Next, when I pass the make command, I am met with the following error (after a long stream of successful commands): Warning in solve.default(rgb): unable to load shared library '/home/sbowerma/Programs/R-2.11.1/modules//lapack.so': /home/sbowerma/Programs/R-2.11.1/lib/libRlapack.so: undefined symbol: _gfortran_compare_string Error in solve.default(rgb) : lapack routines cannot be loaded Error: unable to load R code in package 'grDevices' Execution halted However, I have confirmed that the library lapack.so is, in fact, in the exact position it is supposed to be.

• khotkey script calling bindings stop to work on switching to Quantal

  - by Adobe

  I have many scripts which I call with khotkey. For example I have a hotkey which executes: bk_starts_or_brings.bash 'Konsole' konsole On updating to Quantal -- it stops to work: if I call that key -- it searches bk_starts_or_brings.bash 'Konsole' konsole in google in default web-browser. I tried: sudo apt-get install --reinstall libgl1-mesa-glx libgl1-mesa-dri xserver-xorg-core sudo dpkg-reconfigure xserver-xorg sudo apt-get install build-essential cdbs dh-make dkms execstack dh-modaliases fakeroot libqtgui4 When I start the command from konsole -- it works as expected, but when I call it with khotkey -- it doesn't. I guess someone shadows my keybiding. Or some daemon is not run on startup.

• Port an existing Quickly app from precise to quantal

  - by Ian B.

  I've developed an app using Quickly on a 12.04 system. In preparation for the 12.10 release, I'd like to have launchpad build a version for Quantal so that it can be used and tested by people from my ppa. I'm not willing to upgrade my system yet (I depend on it for work), how can I do this from 12.04 and my current quickly project? I have a virtualbox with 12.10 installed for testing, but I don't want to copy over the quickly project if I don't have to. Ideally, an answer should work with the quickly submitubuntu command so that it is packaged for installation in the /opt/extras.ubuntu.com directory.

• How to copy the file from source to destination only once at a time?

  - by Viswa

  I have to copy the file from my desktop to my mounted directory. I was using the following command to copy the file from my desktop to mounted directory. os.system("cp -f /home/Desktop/filename /media/folder_1"). It works fine. But the problem is while copying the file from my source to mounted directory(folder_1) if any interruption is happens like network down, then the system continuously keep on trying. It couldn't skip that process. Finally, when the network comes the files are again copy to my mounted directory. Due to this continuous trying, next time i try to move the content it throws "permission denied" error. How do i copy the file only once, if any network issues happen then it will not keep try to copy, instead of that, it throws the error. If you know, Let me. Its very useful to me.

• Ubuntu 14.04 LTS AMD64 randomly uninstals packages / applications

  - by Jacob Lindeen

  I am having a strange issue. Occasionally when installing new packages, I will get a system crash notification which I will report. The environment then becomes unstable, unity crashes and all open windows, loose title bars, and the main launcher shuts down. I usually have to run the command unity --replace to restore functionality, but ultimately end up having to reboot. Upon booting back up I find all of my user-installed packages are gone and I have to reinstall them via apt. Please tell me someone else is having this issue, because this is the second system and third install I have had this issue on.

• Capslock as modifier key for AutoKey

  - by nil

  I want to use Capslock as a modifier key for AutoKey shortcuts, and I've successfully remapped it to its own custom key using the terminal command xmodmap -e 'clear Lock' -e 'keycode 66 = F13'. However, AutoKey seems to only allow the modifiers Ctrl Shift Alt Super when setting shortcuts. As a work-around, could I somehow define the shortcuts within the script itself? Would this even be the most efficient work-around? P.S. I found a relevant page, though I'm not exactly sure how to implement it. P.P.S. I found a cheap way to do this by mapping Capslock to Shift+Alt and then setting all appropriate shortcuts in AutoKey with the modifier Shift+Alt. However, I'd really prefer having Capslock as its own modifier. Any help would be appreciated.

• error when installing rmagic gem on Ubuntu 12.04 for Ruby on Rails

  - by PeaceDefender

  0 down vote favorite I am trying to get my Ruby on Rails application working and installing RMagic gem. But I get an error that says "Can't install RMagick 2.13.1. Can't find the ImageMagick library or one of the dependent libraries." Altough I have ImageMagick installed with its dependences. Terminal log : http://pastebin.com/vcgkbwZR I even tried to installed RMagic from Synaptic, but I get the same error when I run "bundle" command. Through my search, some people had problem with lib dependencies, but I believed I have them all installed. Another solution I found is this ( error installing RMagick from gem ) a little bit old and not sure if it is going to work for 12.04. BUT, I don't know where those configurations should go.

• ubuntu 12.04 sound not working in applications

  - by user109887

  I run Ubuntu on a DELL Vostro 3500 laptop. Everything was working perfectly since this morning, after an update... I can't play any multimedia sound anymore, that includes youtube and others, mp3 in Rythmbox, sound of video in VLC. I can see my device in the setting window and I can play tests sound, but nothing else. Any idea? EDIT: I'm switching very often from to HDMI output, which is deconnected right now. I've tried running VLC, and in the audio menu, you can choose the output so now I can listen to music via VLC but not with other programs. Looks like ubuntu is not totally switching the audio device after unplugging the HDMI cable. Is there any command line which can do so?

• Can't open Windows 8 after installing ubuntu 12.04

  - by Pyttar

  Yesterday, I tried ubuntu 12.04 LTS and I liked it, so I installed it in my computer with Windows 8. I managed to create a disk partition in Windows and I named it U:\UBUNTU. Then I installed Ubuntu inside this partition, but now, when I try to enter in my Windows 8, it gives me an error message: error: Secure Boot forbids loading module from (hd0,gpt5)/boot/grub/ntfs.mod. error: no such device: 2402319002316706 error: unknow command 'drivemap'. error: invalid EFI file path. Press any key to continue... What can I do? Please I need urgent help, I need to access to Windows 8 and I don't want to lose any data... I checked for the Windows disk and I can se there's all my information there, so, I didn't lose anything. Thanks.

• Print out the amount of times 2 words appear in the syslog. But also have it tell me how many times for each hour

  - by wolfspinone

  So I'm trying to create a bash script that looks for two words in my syslog file. Then I want the script to print out how many times those two words have appeared. Also I want it to print it out for every hour of the day. So like if the word dog appeared 4 times during the first hour of today, it says Hour one, dog 4. Finally at the end of the script I want it to print out how many times those words appeared all day. The sudo code I have thus far is if 2 > hour find permit find block print both finish if 1 < hour < 2 find permit find block print both finish if 2 < hour < 3 find permit find block print both finish command is grep -o "\WORD\" Syslog.txt * | sort | uniq -c

• Ubuntu Audio Pitch Shifting filter

  - by user777305

  I'm currently developing a video player software which intended to be an embeedded player. I'm using Java with VLCJ library for the video player. What i'm looking is a way, something to transform the audio output to make the output sound as oldman or a kid (pitch shifting, i guess is the name). VLC have this when enabling time stretch, but the video play speed is affected (slower to get oldman sound, but fast-forward-alike to get kid voice effect. Is there any solutions for this? I don't find this feature on VLC(J), so i think what i need is the audio output of the ubuntu itself (Ubuntu 12.04) to do this job. something like filtering audio output system wide. Any software or setting to do this? it also need to be controllable via command line to provide realtime effect changing. Thanks in advance.

• How to run CLI commands from the launcher?

  - by user50849

  I press ALT+F2 key on my keyboard, and get the launcher HUD up. From there I enter a command as I would in a shell, specifically vlc ~/Music/* -Z. If done from a shell, vlc starts and begins to play music. However, when done from the launcher, VLC replies: File reading failed: VLC could not open the file "/home/[username]/Music/*". (No such file or directory) user Your input can't be opened: VLC is unable to open the MRL 'file:///home/[username]/Music/%2A'. Check the log for details. I can't quite figure out what the difference is.

• can't chmod on external hard disk?

  - by G. He

  I have an USB3.0 external hard disk, partitioned to 3 NTFS partitions. When I plug the hard disk in, the 3 partitions automatically mounted under /media. So far so good. I can read and write to files, or mkdir, etc on these partitions. But I can't do chmod/chown on any of the files/directories on these partitions. The owner:group always myself, and the mode are always 700 for directories and 600 for files. I have another partition on internal harddisk also mounted. That partition works fine. I looked the output of mount command, the only difference between mount options is that there is one extra 'default_permissions' on the external hard disks. Anyway I can set the owner:group and mode on these files and directories.

• Is there a way to show icons on a git repo folder like tortoiseGit?

  - by shengy

  Is there a way which could let me know all the file status by just looking at the folder view, like what TortoiseHg, TortoiseSVN, TortoiseGit did on windows? Now my git repo folder looks the same as other folders. If I want to view file status I have to type git status in the command line. I want some icons which could inform me the file/folder status at my first glance on the folder view. I'm using Ubuntu 12.04 EDIT I googled it, and what I'm asking for is called the overlay icon.

• alx driver not working properly

  - by user292768

  My alx driver seems to be working fine for everything except apt-get. I can navigate to web pages, the ping command works just fine, but whenever I try to do apt-get update or apt-get install it hangs on trying to connect to whatever archive it's trying to pull info from. There's no error message, nothing to imply that it can't connect, it just hangs there and does nothing at all. I've tried re installing alx, upgrading/downgrading my linux kernel, downloading source and building alx from scratch, etc etc but nothing works. Does anybody else have this problem/know how to fix it?

• CLI Shared Hosting Management (scripts to manage web users and hosts) [on hold]

  - by aularon

  I am currently administrating two servers: first one has no control panel, I am creating directory structure, setting permission, configuring different aspects (users/php-fpm pools, nginx hosts..) for each of sites. With more clients, I sat up ISPConfig on my second server, everything is easily handled by ISPConfig Web Interface. However, I am searching for a CLI based solution, i.e. a set of scripts to create and manage hosts. Basically, a method to control ISPConfig from the command line (so I can use it over SSH) would be a good start. Does anybody know of such effort? I searched but all I got was web based solutions. Thanks.

• Is there a legit reason as to why Outlook.com premium UI is "not available" in Linux Chrome?

  - by vgaldikas

  Well if you use outlook OWA in Chrome on Ubuntu (or any Linux distro), you will get a stripped down version of it basically. You can get around it by faking your user agent, to appear that you are using FireFox. So my question is.. Is there some legitimate reason Microsoft does that, or are they just being a****s??? I mean once you have the user agent faked, it works perfectly. PS. Just in case anyone else need to use outlook, here is the command to start it with fake useragent: /opt/google/chrome/google-chrome --user-agent="Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US) AppleWebKit/534.4 (KHTML, like Gecko) Chrome/6.0.481.0 Safari/534.4"

• Writing files to an Airport Extreme using afp

  - by Bill Oldroyd

  Using Nautilus I can connect from Ubuntu 12.04 (64-bit) to my Apple Airport Extreme using user & password without a problem. I can read, browse folders and delete files. However I cannot write files, the file is created, but the contents of the file are not transferred. The transfer fails with the error message "kFPMiscErr" which I think means that "authentication has already been established" ?. I have tried the command line tools for access using AFP but these do not work either. Is there a solution to this problem ?

• What should be the correct ownership of /tmp /var /usr and subdirectories?

  - by sbergeron

  For some reason I think the permissions of those were messed up from a small amount of disk corruption I had. This may be a dupe, I don't know but I googled it and didn't find any mention of it. I need to know how the permissions of them should be set up as currently my computer can't actually use the tmp directory and I can't download anything consequently. I have access to the recovery mode command line but while in sudo user prompts it doesn't seem to work correctly. Also something is wrong with package management and I get dpkg: error: unable to access dpkg status area: read-only file system. I know my system is really messed up but I don't want to have to reinstall AGAIN.
