Failed to download package files error

My software center was working when I first downloaded with the new and clean installation of the OS, but now its not working now.

I have tried the sudo apt-get update also with no luck. I would like to download some things from the software center but its asking me to check my internet connection, then it gives me a error code of things it needs to download software from a untrusted source and I have the source list ticked.

I need to know what to do on my end so that I can get it working again or is this something I need to wait for a fix?

  • Please open a terminal, put in sudo apt-get update && sudo apt-get upgrade and post the output here in code tags. That way it provides a more exact description of your problem. – Nitin Venkatesh Oct 19 '11 at 14:09

  • Requires installation of untrusted packages The action would require the installation of packages from not authenticated sources. thats what the box tells me what do i do to get it back running properly and i took a screen shot but dont know how to upload it – Yahmorah Oct 19 '11 at 14:23

I had the same problem, iv tried instead of sudo apt-get update i typed in gksudo apt-get update, it will prompt for ur password, will fetch and download stuff, at the end i got:

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

Then I re-ran the update software it worked ( i have the souce code in the settings ticked)

dont ask me how or why its been 1 month since iv been using ubuntu :P just got lucky!
