Why are the Ubuntu-supplied keys suddenly invalid?

Asked by udippel

This is what I suddenly get:

Reading package lists... Done
W: GPG error: http://packages.medibuntu.org karmic Release: The following signatures were invalid: BADSIG 2EBC26B60C5A2783 Medibuntu Packaging Team <email address hidden>

$ sudo apt-get install medibuntu-keyring
Reading package lists... Done
Building dependency tree
Reading state information... Done
medibuntu-keyring is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

Hmm.

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

It is a disease of Ubuntu's apt-get.
The error message is misleading.
It actually is a corruption in the archives, and can be dealt with simply by
sudo rm /var/lib/apt/lists/partial/*
sudo rm /var/lib/apt/lists/*
sudo apt-get update
