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.)

Edit:

Further information:

cat /etc/apt/sources.list: http://paste.ubuntu.com/786323/

sudo apt-get update: http://paste.ubuntu.com/786326/

Bisigi does not have a PPA repo for Oneiric - my suggestion is to untick this PPA in your software sources and then rerun Update Manager or for a terminal.

Find both by searching from the Dash.

sudo apt-get update && sudo apt-get upgrade

your sources.list look OK

however the sudo apt-get update list looks like you have several "karmic" PPAs - please look through your "software software" list in software sources and untick all of these PPAs.

Your sudo apt-get upgrade is probably the most worry and will explain why you haven't seen any updates for a while.

There is a useful sticky-thread on ubuntuforums describing just this issue and its resolution.

If you change the hostname in /etc/hostname, you must also fix up /etc/hosts so the new name resolves to 127.0.1.1. The safest way is to edit hosts and add the new name, then edit hostname, then o back to hosts to remove the old hostname.

My /etc/hostname and /etc/hosts file is shown - you will need to use your hostname

sudo apt-get update && sudo apt-get upgrade

in addition to performing the function of upgrade, also intelligently handles changing dependencies with new versions of packages; apt-get has a "smart" conflict resolution system, and it will attempt to upgrade the most important packages at the expense of less important ones if necessary. The /etc/apt/sources.list file contains a list of locations from which to retrieve desired package files.[13] aptitude has a smarter dist-upgrade feature called full-upgrade.

sudo apt-get dist-upgrade
