Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I have the small red cross icon in my indicator applet, and upon hovering it says that An error occurred while checking for updates. Because of this, I can't edit the selected repositories through synaptic, which refuses to open the dialog and instead just tries to update the package list.

Your output for update seems to be fine.How do you say that your repository is broken?? –  karthick87 Dec 17 '10 at 17:25
    
Well, it says that the update failed ... nvm, I'm reinstalling. –  aviraldg Dec 17 '10 at 17:43

I just had the same problem and found an updated /etc/apt/sources.list file that differed from the previous one in that it used http://76.73.4.58/ubuntu instead of us.archive.ubuntu.com/ubuntu. When I replaced the newest sources.list file with the old one, the apt-get upgrade worked.

The first step is to cut out the "middle-man" tools and work with commands that are invoked on your behalf:

 sudo apt-get check && sudo apt-get update 
 # you may need to repeat the update if it complains
 sudo apt-get upgrade

Any errors generated by these commands would be most informative when appended to your original question. If the check fails, do as it instructs or stop and post your result.

those work fine, I've tried them out already (and the output is posted above) –  aviraldg Dec 17 '10 at 16:01
