Comment 10 for bug 115087

I can reproduce this bug, but it requires same specific set actions. After that, I get message that update manager could not parse or open /var/apt/list/sk....... (whatever).

I have a wireless network that requires web authentication. After you open the browser you are directed to login page and after you type correct login data, you get access to internet. My guess is that it works by redirecting DNS.

Anyway, if I am connected to wireless, but have not completed web authentication, and in the meantime my package managers start and updates package information, the files in /var/apt/list/sk... would hold HTML code from login page instead package information. After I close update manager and open it again, I get message that it could not parse these files.

Quick solution was to delete all files under /var/apt/list and start update manager again. It will then update package information and it will be able to work. But I guess that average user would not be able to do that.

There can be many solutions to that:
1. when doing update, check that you really have been connected to internet
2. if /var/apt/list files are corrupted that delete them and update source list again (instead of just closing update manager)
