For any given version or installation of Linux Mint, how would I find out which version of Ubuntu it is based on? I'm sure it must be in documentation somewhere right?

  • Is there a file with release in its name in /etc/, something like /etc/*release*? Maybe there is something useful in it. – mnille Mar 16 '16 at 14:10

You'll find Ubuntu version in the /etc/upstream-release/lsb-release file:

$ cat /etc/upstream-release/lsb-release

To figure out which subrelease you are using, you need to know what kernel you are running, e.g. here kernel 3.19:

$ uname -r

Then you compare it with the 14.04.x Ubuntu Kernel Support schedule which says that in my case, the 3.19 kernel matches 14.04.3.

  • Awesome! I was hoping to find out about something just like this! – still_dreaming_1 Mar 16 '16 at 14:43
  • How specific is this information? I am trying to install a driver that says it was designed for 14.04.2 LTS, but my lsb-release file says I am on 14.04. There is also a DISTRIB_DESCRIPTION line that says "Ubuntu 14.04 LTS". Does that mean I have a version just before 14.04.2, or is it just not specific enough to show the last decimal point version number? – still_dreaming_1 Mar 16 '16 at 14:48
  • Answer updated with a method to verify it. – jlliagre Mar 16 '16 at 15:02
