It is possible that the compressed file(s) have become corrupted.
You can use the -tvv option to test integrity of such files.

You can use the `bzip2recover' program to attempt to recover
data from undamaged sections of corrupted files.

A problem occurred during the update. This is usually some sort of
network problem, please check your network connection and retry.

There might be a problem with your repository.

Could you try the update from central repository?
In order to enable it, go to System>Administration>Software Sources and select download from Main Server.

Then try again and report here if it succeeded or not.

pura vida.

i don't know what's wrong but i can suggest a workaround:
upgrade using the ubuntu 10.04 alternate cd:
http://releases.ubuntu.com/10.04/
download the ubuntu 10.04 alternate iso and mount it using the -o loop option.
go to the directory you have mounted the cd and doubleclick cdromupgrade.
follow the instructions. that's it.
hope this helps
