How can I fix a 404 Error using a PPA?
It seems I've run into a small issue after installing Ubuntu 11.10.
After the installation of the upgrade, everything worked fine for a while. One day I went into "UPDATE MANAGER" and checked for updates (This is due to all the recent downloads I made, so I was curious to know if they had to be updated for better use.), but after it read all the updates a error message appeared...
Failed to download repository information
Check your Internet connection.
I then clicked Details to view the problem... (This is what appeared under 'Details')
W:Failed to fetch http://ppa.launchpad.net/bisigi/ppa/ubuntu/dists/oneiric/main/source/Sources 404 Not Found
, W:Failed to fetch http://ppa.launchpad.net/bisigi/ppa/ubuntu/dists/oneiric/main/binary-i386/Packages 404 Not Found
, E:Some index files failed to download. They have been ignored, or old ones used instead.
(Please excuse me for this, and I do apologize. I'm very new at Ubuntu and I'd appreciate some assistance with this. Thanks.)
