The upgrade process appears to be attempting to download package lists from a server, when I have not yet logged into the wireless proxy. Numerous files in /var/lib/apt/lists no longer contain XML, but contain the login proxy html. (The login proxy returns the login screen for any and all web accesses) I have repaired this by getting the files manually with wget, but it happens again about every three weeks. I cannot file a bug with ubuntu-bug because it depends on the update lists to find the package information.
Using Ubuntu 11.04
I am not sure which package is attempting to update /var/lib/apt/lists
I expected the updater to check the file and reject the downloaded file if it is not good xml.
What happens is the login proxy screen html is placed in various files in /var/lib/apt/lists (about 65 of them)
