I want to create a deb string for my APT repository. Now it looks like deb http://sitename $(lsb_release -cs) main

Ubuntu derivatives display their own distribution name in lsb_release -cs (like sarah on Mint). Is there a universal way to get upstream Ubuntu version on Ubuntu itself and its derivatives?

  • cat /etc/version or cat /proc/version might get you what you want. – Android Dev Aug 26 '16 at 23:05

    I need an Ubuntu distribution codename, not kernel version string. – Alexander Shishenko Aug 26 '16 at 23:08

    Oh. Well in any case, I suggest you edit the title. Your question already has 2 close votes for being off topic. – Android Dev Aug 26 '16 at 23:09

Ubuntu doesn't define any standard way to do this. A derivative may or may not include the name of its upstream release somewhere in a file.

The best way is probably to use some package versions to guess the upstream version. The package libc6 would be a good candidate for that, coreutils may be another one.
