Poor handling of broken sources.list files

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

I made this the master for bug 108601 and all its duplicates:

  Update-manager needs help info when terminating on wrong repositories and generally deal better with incorrect sources.list data

since that bug has a lot of garbage comments, making it hard to read. The first couple comments are articulate, though. Also, the launchpad questions related to that bug don't show up here. Just a lot of evidence that users are running into problems with update-manager blowing up on sources.list entries.

Perhaps that bug could be seen as having a slightly larger scope, but I think the basic needs are the same. Thanks.

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

I'm going to work on a detailed design for this, but here's what I'm thinking so far:

If Software Updater does an automatic check, OR you launch it manually, OR you launch Ubuntu Software Center, when sources.list is invalid, then:

a. aptdaemon puts up a dialog explaining the problem and illustrating how it can fix it for you

b. if you choose to fix it, an error tracker dialog appears giving you the option to report the error

c. the program launches as normal.

Perhaps (a) and (b) should be around the other way. Or perhaps they can be merged by introducing a new variation of the RecoverableError dialog.

Thank you so much for using time on this issue.
I`m today using Mac, but I will by a new machine to connect to Linuxprograms as soon as I have time and energy to follow up.
Br,
Svein

Hi , is there a corresponding bug on debian side ?

We try to list bugs that would definitely avoid using command line for users when apt cannot update.

software-center task is no longer valid as that package isn't included in any currently supported release of Ubuntu.
