update-manager doesn't update "last updated"

[WaltSullivan]

Even after I click "Check", and all the whirring stops without error, update-manager tells me "The package information was last updated 9 days ago". Why doesn't update-manager notice the "Check" I've just done?

Status changed to 'Confirmed' because the bug affects multiple users.

By doing "sudo apt-get update -V", I saw the error message:

W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://deb.torproject.org oneiric InRelease: The following signatures were invalid: KEYEXPIRED 1346668560 KEYEXPIRED 1346668560 KEYEXPIRED 1346668560 KEYEXPIRED 1346668560

When I #'d the torproject lines I had in /etc/apt/sources.list, _my_ problem went away. YMMV

This is NOT an update-manager problem (except for not showing the error message).
