error in network upgrade 7.04 to 7.10

Binary package hint: yelp

During auto update (via package update) i got the following message...

Could Not Install 'libpam0g'
Due to being aborted (killed)

I didn't kill it and didn't have any programs open.

This led to many dependency issues with many other packages.

Install closed at 19 minutes remaining.

I restarted my system (ubuntu 7.10 kernel 2.6.20-16)

Half is upgraded and half is not, and runs like shit.

Help!
