I confirm this bug. I got a very similar error message when running update-manager or Synaptic. Ubuntu 10.10. On inspecting the list mentioned in the error message, I found an html-page with a wireless hostspot login page. Thanks Sascha!
When I removed the contents of /var/lib/apt/lists, the error message went away! Happy as I am because the problem i solved, I of course agree that it is a bug that the HTML-files were accepted as lists. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/682753 Title: update manager prints error message at startup and closes -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
