How to Tell What Version of Ubuntu You Are Running

Telling what version of Ubuntu you are running is extremely easy. You would commonly use this command to figure out if you are running Edgy after you upgraded from Dapper .

cat /etc/issue
Ubuntu edgy (development branch)

Note that the version numbers might change over time. I’m running the beta version so that’s what shows up when I run that command. Either way, it should be clear that you are running Edgy.

You can get the version on Debian (also on Ubuntu of course) with: cat /etc/version
