Folks, I'm having a problem with my system update... This message was shown to me at an automatic update made by apt at the system initialization... Could someone help me please?

My system is Ubuntu Hardy Heron 8.04, but I think that anyone familiar with apt update process could help me...

I'm inside a company, behind a "transparent" squid proxy (I don't need to configure it)... We also have dansguard filtering some content...


Apt Authentication Error

Problem during package list update. The package list update failed with a authentication failure. This usually happens behind a network proxy server. Please try to click on the "Run this action now" button to correct the problem or update the list manually by running Update Manager and clicking on "Check".

Bypass your proxy or build your own internal mirror, sometimes proxies can break things.
