I want to launch an EC2 instance on AWS. I want to install Ubuntu Xenial distribution. How do I know which one of these is Xenial?  I see a lot of options like:   Ubuntu Server 18.04 LTS (HVM), SSD Volume Type - ami-0b76c3b150c6b1423 Ubuntu Server 14.04 LTS (HVM), SSD Volume Type - ami-001dae151248753a2 Deep Learning AMI (Ubuntu) Version 23.0 - ami-0726ab58f406b644f Deep Learning Base AMI (Ubuntu) Version 18.0 - ami-00c2ec90e50ed2f33 Ubuntu Server 16.04 LTS (HVM) with SQL Server 2017 Standard - ami-f13ff693 Ubuntu Server 14.04 LTS (HVM), SSD Volume Type - ami-0d21bd76bdbb39f53   Update  The reason I want Xenial is that Galera cluster is already built for xenial:

Is there a list of Ubuntu versions with default corresponding Linux kernel versions somewhere?  I would specifically like to know the most recent version of Ubuntu that still used Linux Kernel 2.x.

I am running Xenial 16.04 and looking to install packages to an external drive - my computer has a 32gb SSD so it would be very useful to me to be able to use an external drive.  In a quick search I found a framework called  which seems to be designed to package all dependencies for a program (chromium, GIMP, some python packages, etc), but haven't had time to look into it.   seems to be looking for the same solution I am.   Thanks, Chris

I know this is probably a question this is asked over and over again but I'm not finding anything close to an answer that I need.  I am installing Ubuntu 13.04 on my Lenovo x130e netbook .  It has been a long time since I have used Ubuntu (Hardy Heron) so I'm not exactly sure on how to go about this.  Here's my system specs:  CPU: AMD e450 apu dual 1.65Ghz RAM: 8Gb DDR3 Corsair Vengence 1066mhz SSD: Crucial M4 128Gb SSD Vid: Radeon HD6320 384Mb  Now here's my questions:   Since I am running a single SSD and have plenty of RAM, should I use a swap file?  If so how large of a swap? I am going to use .ext4 filesystem but is there any specific way I should partition my drive?  (1 partition for /home, another for boot, etc...) I am planning to upgrade to 13.10 when it releases, is there anything I should keep in mind until then?   I have never really used a forum before so I figured that this would be the best time to start.  I have decided that I am tired of having to deal with Microsoft and want to break free of their bloated software.  I have read through your forums many times before and found that this is probably the best place to begin the process of reacquainting myself with Ubuntu.  Thanks for your time!

Not sure if there is a better communication mechanism for asking this question. Ubuntu 12 is EOL April 2017. Do corporations have any option to extend support on 12?  Thanks

As my fedora repos are way behind and still on blender 2.69, I've gone and compiled the latest myself. Everything seems to work and is quite recent. I can even bake CPU SSS, which is great. However I still get the error "Volumes/SSS not supported on GPU". Have I missed a flag or library (eg OSL support) in CMAKE or is this still on the todo list? If its just not finished yet, I don't mean to rush the devs but definitely looking forward to its release.

On Ubuntu, the string returned by uname -r is always of the form x.y.0-z-generic (i.e., 3.19.0-21-generic). Compiling Ubuntu's kernel ends up with a string that is of the form x.y.z (i.e., 3.19.8), the actual version of the kernel that is used. What does the z represent in the first case? Is that the EXTRAVERSION parameter or is it something else? How do I get the version string of my build of Ubuntu to match the official one?

My system:  $lsb_release -a No LSB modules are available.

It's a missing feature or a bug. I found a reference here with a patch:   And looks like that in other distros like debian, there is already a testing build of Xvfb with support:   I am trying to run a program throught Xvfb, and it returns the following error:  Xlib:  extension "RANDR" missing on display ":99".   The program works if I run it via ssh/command line. The problem appears to be the the lack of support for "RANDR" in xvfb.  My question is: what is the easiest way to get xvfb with "RANDR" support in my system?

I have a Red Hat Enterprise Linux server (7.5 x86_64). I have OpenSSH version 7.4. I was asked to upgrade it to a later version for security reasons: Nessus states that . However the Red Hat software and downloads does not have the latest package RPM.  I found some clues on where to get the latest package for OpenSSH. I found , however, I do not know on how to upgrade it and trust this website. I do not want the SSH and other configuration to be modified by the ugrade.  I did find links but however they are not useful, for example .  I would like to know how to upgrade OpenSSH without using yum.

I've read various questions/answers such as this one:        However I have an ext3 partition I need to extend that isn't part of a LVM group and never will be.  What steps do I need to take to achieve this without losing data?  I'm running CentOS 6.4 x64 (text only, no GUI/X etc) on XenServer. I've already resized the XenServer virtual disk that the partition (/dev/xvdb1) resides on (it's the only partition).

The title itself is more than self explanatory. I simply need a way to install Oracle's 11g R2 in the latest version of Ubuntu, I'm using a 32-bit OS, and I need to know how to install the x86 version. I also have a 64 bit desktop and I need the install the x86_64 version. Can anyone help me?

I want to know where I can find updated information about all the stable and in-development versions of Ubuntu, where I can find this information?     This question is meant to be a canonical question. It expects to answer the following questions:         Is X version stable yet?   Is X version in beta?   Is X version still supported?   What versions are still supported?   What are the versions in Beta/Alpha?   Until where X version will be supported?   Have X version ceased support?   When will be X version released?   Where I can download any release?   When will the next LTS version of Ubuntu be released?         The list is not exhaustive.

This doubt is hitting me since 2-3 days, so I decided to test it myself. What I did is I installed Ubuntu 16.04.4 in VMWare and edited /etc/apt/sources.list and replaced xenial with bionic using:  sudo sed -i 's/xenial/bionic/g' /etc/apt/sources.list   Then I ran  sudo apt-get update &amp;&amp; sudo apt-get upgrade    I was able to upgrade to 18.04, confirmed by using lsb_release -a. However, I encountered some problems like:   apt does not have a stable CLI interface. Use with caution in scripts. unmet dependency of  python3-aptdaemon.pkcompat Release 'bionic-backports' for 'appstream' not found Broken Unity   I solved all the errors and installed gnome and gdm3.   So, I just want to know is it a good idea to edit sources.list? I know that my system might broke but is there any other specific reason not to use this.  Note: I tested this on Ubuntu 16.04 in VMWare to clear my doubts only.

I built myself a computer a couple of years ago and run it now with Ubuntu 9.04 under Xen 3.0. I'm not a hardware expert by any means, but I managed to make it all work. However, due to the lack of support for Xen by Ubuntu, I can't easily upgrade to more recent versions of the operating system. I have therefore decided to switch from Xen to KVM, which is supported by Ubuntu.  My current CPU, an Intel Pentium 4 Processor 640, is not KVM-compatible (i.e. does not provide VT-x or AMD-V). My motherboard is an ASUS P5LD2. I have looked for other processors which work with the ASUS P5LD2 motherboard, implement VT-x or AMD-V, and are available in shops near me.  The Intel E6700 seems to fit the bill.  If I switch off my computer, replace the Intel 640 with an Intel E6700, update the BIOS for the E6700, and switch it back on again: will it still work with the existing installed software (Xen 3.0, Ubuntu 9.04 etc.)? Or do I have to reinstall everything from scratch?  Steve
