Ubuntu: Trouble getting updates Ubuntu 12.04 [duplicate]

How can I fix a 404 Error using a PPA?

Could someone help me decipher why I am getting this issue? I've tried updating my packages several times and I always get this same message with the update manager.

Things I've already checked:

  • I am connected to the internet (as shown by my being able to post this question)
  • All other internet related things work fine, USC etc.
  • I am running Ubuntu 12.04 on a HP pavillion dv6000, not dual booting.

Here's a screenshot of my problem, have I missed a crucial update? I'd not have thought so seeing as it's been roughly a week during which I didn't turn on my laptop, but if anyone has any idea/suggestions I'd be grateful for any input.

The PPA mentioned in the error is the root cause of this error. Remove this PPA annd try to update again. Try the following in terminal:

sudo ls /etc/apt/sources.list.d  

Here you should see a file named crebs.list (or something like that). This PPA is included in your source lists. Remove it using the following command:

sudo rm /etc/apt/sources.list.d/crebs.list  


sudo add-apt-repository --remove ppa:crebs/ppa

It also gives the GUI way to fix this error.


You seem to have added a PPA whose link has since broken, see "How to remove a repository" on how to get rid of the PPA.
