Bug Description

Had some packages installed from my ppa. I had successfully upgraded to them and purged them in the past. Attempted ppa-purge, failed. Verified that the package versions from my ppa were installed ("wayland" in version number). Tried re-adding ppa with ppa-add, then re-running ppa-purge. Same result. Looked at /etc/apt/sources.list.d/darxus-wayland-gtk-precise.list, noticed everything was commented out. WTF? Uncommented lines, re-ran ppa-purge, worked.

What commented out the lines in /etc/apt/sources.list.d/, and why didn't they get uncommented / re-added when I re-added the ppa?

$ sudo ppa-purge ppa:darxus/wayland-gtk

ppa-purge disables them even when it fails, these changes should obviously be reverted on failure.

I wonder is it always desired that ppa-purge reverts changes to sources.list.d, if apt-get fails? What should it do to the packages that were successfully downgraded/purged in case apt-get failed due to some other packages (or is this a realistic case)?

What is ppa-add? I don't have it in Trusty. Why did first run of ppa-purge fail? Maybe the PPA was commented out before that for some reason?

If any packages fail to download apt should abort without removing any packages, so in this case yes

it should be unlikely to end up in a state were only some packages were downgraded, but if this did happen then ppa-purge is not going to be clean it up later, so in this case (if it can be distinguished from exit codes) could warn the user how to manually find and remove 'foreign' packages and leave the ppa disabled

I suspect ppa-add really meant apt-add-repository, that was in the past buggy when it came to re-enabling ppa's that had been commented out, but that should be fixed these days.

still valid for yakkety.

In theory ppa-purge revokes than to take trust away from a ppa-repro?

Flames_in_Paradise, I do not understand your question.

I have pushed ages ago a revision that should fix this and some other bugs:
http://bazaar.launchpad.net/~jarnos/ppa-purge/apt-get/revision/64

However, the commit was not accepted due to being too big for single commit.
I have been working on another commit that is slightly different and thar has been done in git by smaller steps. Hopefully I am able to push it soon.

Anyway, you could test the revision I have already pushed.
