I'm having problems with the Ubuntu Software Center, when I try to open it, after two seconds it closes. I've tried reinstalling it but I keep getting this when I try sudo apt-get update:

W: Failed to fetch  404  Not Found

W: Failed to fetch  404  Not Found

E: Some index files failed to download. They have been ignored, or old ones used instead.

Can you add the contents of /etc/apt/sources.list – Mitch Jun 9 '13 at 17:35
The contents of /etc/apt/sources.list are generally not relevant to these sorts of "problems" unless the file was edited by hand. Adding PPAs via add-apt-repository or software-sources typically adds them to a new file in /etc/apt/sources.list.d/ rather than in sources.list directly (which really should be kept pristine). – dobey Jun 9 '13 at 18:36

Those messages aren't really errors. They are simply telling you that that PPA does not support your version of Ubuntu. They are not preventing you from just running sudo apt-get install software-center which will still work.

Remove that PPA (deb raring main) from your sources. It is no longer in use. Updated versions of software-center are provided via the Ubuntu One team's PPAs:

  • ppa:ubuntuone/stable
  • ppa:ubuntuone/beta
  • ppa:ubuntuone/nightlies

These PPAs include the Ubuntu One client packages, Software Center, and any necessarily updated dependencies. However, the version of software-center in Ubuntu 13.04 is still pretty much up to date, as it was only released a couple months ago.

So, which ones do I have to remove? And, more important, how? I'm a newbie – RbeJG Jun 9 '13 at 18:02
