Bug description:
Thank you @jbicha for the original bug report!
[ Impact ]
Currently ppa-purge fails to purge packages on distribution using the deb822 source format. Currently mantic and noble make use of this format and are affected by this issue.
When running ppa-purge to remove a custom PPA, ppa-purge fails to disable the custom PPA since it cannot disable deb822 sources and leads to apt still querying the ppa when running:
$ apt update
In older versions of ubuntu, PPAs used the ".list" format which could be disabled by simply commenting out the "deb" line with a "#". This was the method that ppa-purge used to disable PPAs.
This new patch allows ppa-purge to detect and disable deb822 source files by adding an "Enabled: no" field in each component section of the deb822 file. It also removes any line that starts with "Enabled:"
to make sure the resulting file is clean.
[ Test Plan ]
The changes were tested on both mantic and noble in a lxc container using the oibaf mesa PPA (https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers) as the test PPA.
The following steps were recorded in a noble lxc container.
- First make sure that mesa-utils is installed in your environment:
$ sudo apt update && sudo apt install mesa-utils
- Add the oibaf PPA to your system using the following command:
$ sudo add-apt-repository ppa:oibaf/graphics-drivers
- Make sure that the mesa-utils packages were upgraded after adding the PPA:
$ sudo apt update && sudo apt upgrade
$ dpkg - l | grep mesa
- output should be similar to the following:

- Install and run ppa-purge:
$ sudo apt install ppa-purge
$ sudo ppa-purge ppa:oibaf/graphics-drivers
- ppa-purge will report at the end that none of the oibaf packages
need to be downgraded/removed:

All packages are up to date.
[ Where problems could occur ]
- Patch could fail to disable the PPA if an "Enabled: yes" entry was not detected and removed or if no Components line was found. This would cause ppa-purge to fails again in the same manner it is currently failing.
- The patch could also fail to detect the file in its entirety if the file name does not end with ".sources" or if its name does not follow the pattern $PPAOWNER/$PPANAME
[Original Description]
Test Case
---------
From Ubuntu 23.10:
sudo apt install hello
sudo add-apt-repository ppa:jbicha/temp
sudo apt upgrade
apt policy hello
sudo ppa-purge ppa:jbicha/temp
apt policy hello
reveals that the PPA version of hello is still installed
Also /etc/apt/sources.list.d/jbicha-ubuntu-temp-mantic.sources
is still present and active
What Should Happen
------------------
ppa-purge should disable the PPA and reinstall any PPA packages with the version apt currently sees.
Background
----------
add-apt-repository creates deb822 sources lists, starting in Ubuntu 23.10
https://discourse.ubuntu.com/t/spec-apt-deb822-sources-by-
default/29333
Other Info
----------
add-apt-repository has a --remove option
But it does not do the reinstall part which is important
Honestly, that feature is so important, I suggest that add-apt-repository take over the functionality of ppa-purge so that we always get the ppa-purge behavior
