I have created a new list of sources from the ubuntu's source-o-matic very useful I might add.

I know my sources arent the problem and i have also downloaded and reinstalled apt

which i got from another post in this forum

what now?

Thanks

Can you please post your sources.list?

This is my original file:

deb http://gb.archive.ubuntu.com/ubuntu/ dapper main restricted
deb-src http://gb.archive.ubuntu.com/ubuntu/ dapper main restricted

I then backed up the above file and made this new one with the same problems/errors:

I have just tried to update after leaving for a day and now its working...

Will post back if it fails again. Hopefully wont need to.

Probably a problem with the British mirrors. Eventually passes.
