Distributor ID: Ubuntu
Description: Ubuntu 11.10
Release: 11.10

Oneiric is no longer supported in any way. There are no more packages (hence the 404 error) and there is no community support.

I suggest you wipe Oneiric off your system and do a clean install of Trusty which is LTS and supported til April 2019.

You can restore your user data from backups.
