Ubuntu’s default packages ship Subversion 1.6 with the 12.04 distribution. This is annoying if you want to use the newer Subversion 1.7, without upgrading your OS, and especially if you’re dealing with newer working copies:
svn: The path '.' appears to be part of a Subversion 1.7 or greater working copy. Please upgrade your Subversion client to use this working copy.
Turns out there’s an official Subversion PPA on Launchpad, so for Ubuntu 12.04 all you have to do is add the following couple lines to your
deb http://ppa.launchpad.net/svn/ppa/ubuntu precise main deb-src http://ppa.launchpad.net/svn/ppa/ubuntu precise main
And upgrade Subversion to its latest version with apt-get:
sudo apt-get update sudo apt-get install subversion
At this point you should be running the latest, and the greatest:
$ svn --version svn, version 1.7.8 (r1419691) compiled Mar 23 2013, 23:38:40
Hope this helps!
