How do I check the version of Ubuntu I am running?

Question

How can I check my current Ubuntu version through the command-line and GUI?

Since this came up in my search first I'll post one alternative: checking `/etc/apt/sources.list` and seeing what repo it's pulling from. This was the only way I could figure out what Ubuntu image I was running inside of a `docker run -it --rm` which apparently doesn't install `lsb_release` — Bratchley, Nov 07 '17 at 16:10

As said in the official page, use:

lsb_release -a

Your version appears on the "Description" line. If you just want that line, type lsb_release -d.

If you want to check it through your desktop environment, you can check System Settings → Details, which shows the data like this:

Alternatives are:

hostnamectl
cat /etc/*ease

See a sample output of lsb_release, hostnamectl, and cat /etc/*ease calls:

$ lsb_release -a

why is it this weird command? I can't ever remember it. Why not something like `os -v`. Its sort of annoying. – Charlie Parker Dec 16 '16 at 07:07

@CharlieParker See [Linux Standard Base](https://en.wikipedia.org/wiki/Linux_Standard_Base). – Aaron D. Marasco Sep 16 '17 at 04:22

Ubuntu's official LTS Docker image (`ubuntu:xenial`) does _not_ have `lsb_release`; I had to parse `/etc/os_release` as noted in another answer. – Aaron D. Marasco Sep 16 '17 at 04:24

@CharlieParker According to `man lsb_release`, LSB stands for [Linux Standard Base](https://en.wikipedia.org/wiki/Linux_Standard_Base). – Serge Stroobandt Sep 18 '17 at 09:19
@CharlieParker Adding the following to your .bashrc: `export OS_CODE_NAME=$(lsb_release -cs); export OS_CODE_VERSION=$(lsb_release -rs)` allows you do a `env | grep OS`, which might be a bit more convenient. – spyle Nov 29 '17 at 23:05

@CharlieParker `alias os="lsb_release -a"`. I agree this should be easier by default, but the beauty of UNIX is it allows you to fix stuff like this yourself without much of a fuss. – Austin Dean Jun 13 '18 at 14:57
This does not seem to be working in Ubuntu 18. In 16 it does (and in the docs you linked, it shows 14). – wordsforthewise May 14 '19 at 03:58
`bash: lsb_release: command not found` and `E: Unable to locate package lsb_release` on Ubuntu 18 – techkuz Dec 18 '19 at 10:33
@JoãoRochadaSilva It's actually from the 2000's. – JoL Apr 17 '20 at 00:37
Code for ones which just needs short release description: `sb_release -d | grep -ioP ':\s+\K(.+?$)'` – Agnius Vasiliauskas Oct 02 '20 at 08:45

Use:

cat /etc/*release

In my case it produced the following output:

DISTRIB_ID=LinuxMint
DISTRIB_RELEASE=17.2
DISTRIB_CODENAME=rafaela
DISTRIB_DESCRIPTION="Linux Mint 17.2 Rafaela"
NAME="Ubuntu"
VERSION="14.04.3 LTS, Trusty Tahr"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 14.04.3 LTS"
VERSION_ID="14.04"
HOME_URL="http://www.ubuntu.com/"

`cat /etc/lsb-release` – Dec 06 '16 at 17:35

On current mint releases `/etc/upstream-release/lsb-release`might be of interest as well. – cheffo Apr 17 '17 at 19:26

This works everywhere I tested. lsb_release doesn't work on all versions. for example in Ubuntu 16.04 on Docker. – Jay Jun 03 '17 at 07:11

In my experience this is a more robust approach, some distributions will not have the lsb_release command – RutgerH Sep 27 '17 at 12:23

How to get just the DISTRIB_CODENAME e.g. "xenial" ? – RutgerH Apr 09 '18 at 11:43
using command to get directly `grep 'CODENAME' /etc/lsb-release | cut -d'=' -f2` – Larry Cai Oct 23 '18 at 12:16

Good answer, as Ubuntu image installed from docker does not have lsb-release installed. – Binita Bharati Feb 04 '19 at 07:08
best solution, work in most of cases. – tim Apr 01 '19 at 00:51
This one works also on WSL – Niko Föhr Feb 14 '23 at 08:20

Use this in the terminal to show the details about the installed Ubuntu "version":

lsb_release -a

This may be more verbose than you need - maybe you just wanted to see 15.4? It can be shown separately by the option -r (--release):

$ lsb_release -r
Release:        15.04

Add -s (--short) for use in a script:

$ lsb_release -r -s
15.04

See the further examples for the more useful options -c (--codename) and -d (--description), and both combined:

$ lsb_release -c
Codename:       vivid
$ lsb_release -d
Description:    Ubuntu 15.04
$ lsb_release -dc
Description:    Ubuntu 15.04
Codename:       vivid

Note you can get similar information about the currently running kernel, and the hardware by the similar command:

$ uname -a
Linux mybox 3.19.0-31-generic #36-Ubuntu SMP Wed Oct 7 15:04:02 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

`lsb_release -rs` and `lsb_release -cs` are very useful in scripts. — frozen-flame, Jun 27 '18 at 03:08

Executing this in Terminal will give you all of the information you could possibly need:

lsb_release -a

And you can access it in the GUI by going System Settings > Details:
