I have installed O A.D game using ubuntu universe repository.
But www.play0ad.com reports there are development releases(but not stable) can install using develpment repository.
So I added development repository
Then I update the system
But terminal says following error
W: Failed to fetch http://ppa.launchpad.net/wfg/0ad.dev/ubuntu/dists/precise/Release Unable to find expected entry 'precise/source/Sources' in Release file (Wrong sources.list entry or malformed file)
Please help me to resolve this problem.Thank you!
