• How to install gnome shell extensions offline?

  - by nosklo

  I know how to go to the https://extensions.gnome.org/ website and download gnome-shell extensions, but now I need to install some extensions available there on a computer without any internet access at all. It is in a internal corporate network and there's no way I can get outside internet access on it, so I must find another way. I can copy files in a usb disk. At my home computer, I have found my extensions at ~/.local/share/gnome-shell/extensions/ but just copying this folder to the target corporate computer didn't do the trick. Running gnome-tweak-tool gives me a "Install Shell Extension" button but I don't know how to download an extension in a format acceptable to install using this button. I have tried to point to the folder above but it didn't work either. What do I need to do?

• How do software updates work on Ubuntu?

  - by Jonas

  I would like to know how software updates work for my Ubuntu Server 10.10. I have been recommended to use apt-get install for installing new software and apt-get update for updating software for a Ubuntu Server in production use. Because these packages are tested for Ubuntu in contrast to download source code and compile the software on the box. But on my Ubuntu Server 10.10, I don't get the latest stable version of PostgreSQL (9) or the latest stable version of Nginx (8) using apt-get install. So how is this working, will these software be updated when I later run apt-get update or do I have to later run apt-get install again, or do I have to wait for the next release of Ubuntu to get them? And are patches and security updates managed in the same way? Or can they be updated automatically? If there is such a setting, how do I check what my system is using?

• Changes to keyboard layout resetted on restart

  - by Matthieu Napoli

  I edited /usr/share/X11/xkb/symbols/fr to customize the french-dvorak layout. I then selected french-dvorak layout (instead of french). Now when I restart Ubuntu, I end up with the non-edited french-dvorak (my changes are ignored). But if I switch to french, then back to french-dvorak, my changes are now taken into account... How can I have my custom french-dvorak on startup? Is there some sort of cached version of the keyboard layout? I don't understand how it can switch me to the official french-dvorak because I changed it, so it should no longer exist.

• mpirun -np N, what if N is larger than my core number?

  - by Daniel

  Say I have a 4-core workstation, what would linux (Ubuntu) do if I execute mpirun -np 9 XXX Q1. Will 9 run immediately together, or they will run 4 after 4? Q2. I suppose that using 9 is not good, because the remainder 1, it will make the computer confused, (I don't know is it going to be confused at all, or the "head" of the computer will decide which core among the 4 cores will be used?) Or it will be randomly picked. Who decide which one core to call? Q3. If I feel my cpu is not bad and my ram is okay and large enough, and my case is not very big. Is it a good idea in order to fully use my cpu and ram, that I do mpirun -np 8 XXX, or even mpirun -np 12 XXX. Q4. Who decides all of these effciency optimization, Ubuntu, or linux, or motherboard or cpu? Your enlightenment would be really appreciated.

• Mirror using apt-mirror and exclud certain sections/categories

  - by Onitlikesonic

  I'm currently using apt-mirror to create a local mirror of the debian repositories. As the mirrored repositories will be used only by machines destined to be headless servers and as an effort to reduce the current mirroring size (around 75GB), categories like games and possibly others will never be needed. How can I go about specifying (on the mirror.list perhaps?) what sections/categories I want to be excluded from the mirroring? Maybe a bit subjective, but apart from games what other sections/categories could be "safely" ignored from the mirroring for my environment purposes? My mirror.list looks as below since all the machines are using precise. # MAIN deb-amd64 http://archive.ubuntu.com/ubuntu precise main restricted universe multiverse deb-i386 http://archive.ubuntu.com/ubuntu precise main restricted universe multiverse # SECURITY deb-amd64 http://archive.ubuntu.com/ubuntu precise-security main restricted universe multiverse deb-i386 http://archive.ubuntu.com/ubuntu precise-security main restricted universe multiverse Also, what others would you recommend adding to the list to be mirrored for a relatively stable environment? Again I understand this is subjective, just looking for some pointers. Much appreciated in advance

• How do I enable WebGL sites with Firefox 4 Beta?

  - by Greg Grossmeier

  I am using Firefox 4.0b12 from the Mozilla Team's "Firefox Next" PPA. My about:config has webgl.enabled_for_all_sites set to true as most guides recommend that and also say that is all that is needed. It doesn't work for me. The main Mozilla Demos page ("Web O' Wonder") gives me: Unfortunately, while your browser supports WebGL, your video drivers may be too old. To view any of the demos tagged with WebGL, try updating your drivers at NVIDIA, AMD, and Intel. You can still watch screencasts of the WebGL demos or fully experience our other non-WebGL demos without updating. This Mozilla demo gives me "No WebGL context found."

• Why Does Ejabberd Start Fail?

  - by Andrew

  I am trying to install ejabberd 2.1.10-2 on my Ubuntu 12.04.1 server. This is a fresh install, and ejabberd is never successfully installed. The Install Every time, apt-get hangs on this: Setting up ejabberd (2.1.10-2ubuntu1) ... Generating SSL certificate /etc/ejabberd/ejabberd.pem... Creating config file /etc/ejabberd/ejabberd.cfg with new version Starting jabber server: ejabberd............................................................ failed. The dots just go forever until it times out or I 'killall' beam, beam.smp, epmd, and ejabberd processes. I've turned off all firewall restrictions. Here's the output of epmd -names while the install is hung: epmd: up and running on port 4369 with data: name ejabberdctl at port 42108 name ejabberd at port 39621 And after it fails: epmd: up and running on port 4369 with data: name ejabberd at port 39621 At the same time (during and after), the output of both netstat -atnp | grep 5222 and netstat -atnp | grep 5280 is empty.

Whenever I try to relaunch ejabberd with service ejabberd start, the same thing happens - even if I've killed all processes before doing so.

• MySQL fails to start after upgrade to 12.04?

  - by radek

  I'm a newbie on MySQL ground so bear with me. I've just finished upgrading 11.10 to 12.04. Everything seemed to work without any hiccups and all my software and settings are working fine. Apart from MySQL. When I try: sudo start mysql I receive an error: start: Job failed to start Where can I possibly diagnose what the problem is? And (hopefully) - how to sort it out? (I disabled automatic start following advice here if that is of some importance) Update 1: Both outputs of: cat /var/log/mysql.err cat /var/log/mysql.log are empty. Output of dmesg | grep mysql: [ 1401.785141] type=1400 audit(1335619832.181:25): apparmor="STATUS" operation="profile_replace" name="/usr/sbin/mysqld" pid=16165 comm="apparmor_parser" [ 1401.791089] init: Failed to spawn mysql main process: unable to execute: No such file or directory Update 2: As indicated by AWinter below - it seemed that MySQL disappeared automagically after upgrade and had to be reinstalled.

• Security considerations for default install of Ubuntu

  - by cpedros

  So with an old burned install CD of Feisty Fawn I went through the process of completely formatting the Windows OS and installing Ubuntu on an old XP laptop. I then went through the online upgrade to 10.4 LTS, only installing the gnome desktop environment package in the process. My (admittedly very open) question is that in this state and online, what security considerations do I have to immediately make for the default install? I understand that a lot of this swings on my intended use of the server, but just sitting there online what risks is it exposed to (this obviously goes far beyond the realm of linux, but I am not sure how these risks are accommodated in the default install). For example, I believe there is a firewall installed with Ubuntu but by default it allows all traffic. Any other guidelines would be much appreciated. Thanks

• Lubuntu 12.04 PPC slow startup and shutdown

• How should I configure TRIM Support for LVM logical volumes?

  - by Zack Perry

  I am setting up a notebook for software demo purpose. The machine has a Intel Core i7 CPU, 8GB RAM, a 128GB SSD, and runs Ubuntu 12.04 LTS 64bit desktop. As it is, the SSD is configured to have a single volume group, with /boot, /swap, and / all in their respective logical volumes. They collectively consume 30GB space. I plan to use the remaining for logical volumes for KVM guests, all run Ubuntu 12.04 Server I would like to ensure that the SSD is utilized optimally. Although on this site, there are some great info about setting up TRIM support for file system setups that do not involve LVM, I have not found explicit guide regarding my planned setup. I did found this page which talks about adding issue_discards in /etc/lvm/lvm.conf. But in said file on my machine, I didn't find the cited content. I double-checked man lvm.conf(5), didn't see any mentioning of this option either. Thus, I'm not sure what to do. Furthermore, even say adding the option is the right thing to do, should I in my machine's /etc/fstab still add mount options such as noatime etc? Any tips, pointers, and/or further guidance are greatly appreciated.

• Is GParted safe?

  - by Olivier Pons

  I want to resize my partitions: I have 3 partitions: Ubuntu 10.04 Windows Seven Ubuntu 11.10 It's booting with the boot installed by the Ubuntu 11.10 version. I want to expand (only expand) all the 3 partitions. My HD is 1,8 Tb so it's big and I have no possibility to save before expanding. So my question is: if you tell me GParted work 99,99 % of the time, I'm willing to take the risk. If you tell me GParted work 90 % of the time, I won't take that risk.

• How do I know I'm using kubuntu?

  - by Adobe

  I installed Kubuntu image long time ago, and did several release upgrades since that. I have package kubuntu-full installed, and boot into KDE. Currently it looks like I'm using ubuntu: ~: lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 13.10 Release: 13.10 Codename: saucy There's not a single kubuntu word in my /etc/apt/sources.list, or is it Kubuntu = Ubuntu - Unity + KDE now? For example there's a Pre-Alpha Ubuntu Thar already, but no Kubuntu one. Would I get Kubuntu Thar, by installing Ubuntu Thar in the way mentioned above? Probably Kubuntu team now are the guys responsible for KDE working in Ubuntu.

• Trying to format drive fails

  - by david

  since I will be doing an internship for which i need to use Windows software, I have decided to ruin my day trying to remove my Ubuntu 12.04, install Win XP SP3 (since the DualBoot theme from ubuntu suggests to first install Windows and then Ubuntu, for problems with the bootloader if you do it the other way around) and then reinstall Ubuntu 12.04 since I would like to keep using it as my primary operating system, using WinXP exclusively for the internship. Other than that, I would like to have a partition for the data, which can be used by both Ubuntu and Windows. So now, I have used the disk utility run from an ubuntu-live cd to format my drive with Master Boot Record (being conscious of the fact that this way I will lose all my data, which I have saved on an external drive before, and that my Ubuntu won't work anymore afterwards), creating partitions for Windows (NTFS), personal data (FAT, since as far as I know both Ubuntu and Windows can deal with this), a Swap partition for Linux, and one partition for Ubuntu (ext4); trying to install Win XP from cd gives me a blue screen, which stops the setup and telling me to remove all recently installed drives and to run CHKDSK. So I thought, that maybe Windows doesn't like pre-partitioned drives for its installation and thus I need to re-format my hard drive in order to have a completely "new" drive, which I can then, during the Windows-installation, partition in order to create the partitions I need. Trying to do this, though, the disk-utility run from the live-CD gives me this warning: Error creating partition table: helper exited with exit code 1: In part_create_partition_table: device_file=/dev/sda, scheme=0 got it got disk committed to disk BLKRRPART ioctl failed for /dev/sda: Device or resource busy I do not understand why it tells me that the hard-drive is busy, because, as stated above, I am doing all this from a live-CD. Thus, my questions are: How can I resolve the error given by the disk utility? Does it make sense to use four partitions in the way mentioned above? And if not so, which partitions should I create? Can I, theoretically, partition my drive from an Ubuntu live-cd in order to create the partitions I want and to install first Windows and then Ubuntu? Thanks for any help, David

• alien deletes .deb automatically while converting from .rpm

  - by Andre

  I'm trying to convert .rpm to .deb using alien. alien -k libtetra-1.0.0-2.i386.rpm Alien says that: libtetra-1.0.0-2.i386.deb generated But when I check the folder - there is just original .rpm and no .deb. Also - I can see that for a split second there is a .deb file in a folder. so it looks like alien create .deb and deletes it right away. I suspect that it's maybe because I run 64 bit os and package is 32? Can somebody explain why alien deletes .deb automatically?
