I just installed Linux Mint 5 x86_64 earlier today. Even though it's not officially ubuntu, since it is based off of Hardy, I thought I could get some help here.

Tried to update the the packages, and synaptic failed. Been doing a few things on my own, cleared the downloaded packages, retrying. Didn't help.

Code:
sdellysse@uuber ~ $ sudo apt-get update && sudo apt-get upgrade
