Bug Description

Removing and readding a PPA can cause invalid repository lines. This doesn't seem to be the case with all repositories, but I've reproduced it consistently with the below steps.

Steps to reproduce.
1) apt-add-repository ppa:mythbuntu/0.25
2) apt-add-repository --remove ppa:mythbuntu/0.25
3) apt-add-repository ppa:mythbuntu/0.25

Expected result: repository .list file contains
deb http://ppa.launchpad.net/mythbuntu/0.25/ubuntu oneiric main
deb-src http://ppa.launchpad.net/mythbuntu/0.25/ubuntu oneiric main

Actual result: repository .list file contains
deb-src http://ppa.launchpad.net/mythbuntu/0.25/ubuntu oneiric main
src http://ppa.launchpad.net/mythbuntu/0.25/ubuntu oneiric main

This causes apt to fail with an invalid line error.

Although it doesn't happen on all repos, so there is likely a deeper issue, this could probably be resolved by also resolving bug #889406.

Thanks for your report - I managed to reproduce the bug.

However, you mentioned that the bug does not occur on all repos; could you please specify a repository for which removing and readding it does not cause problems? Thanks!

It didn't seem to occur when I was testing our 0.24 repo

I tried using the "ppa:mythbuntu/0.24" and the bug still occurred.

However, I think enough information has been collected and is ready to be worked on by an Ubuntu developer. Thus, I'm asking for this bug to be marked as Triaged and let them handle it from here. Thanks for taking the time to make Ubuntu better!

[Note to developers: as Thomas suggested in comment #2, bug #889406 is probably closely related to this. I'm asking that to be marked Triaged as well].
