Bug Description
[impact]
Currently there are different versions of awk installed on a Ubuntu system based on the flavor the user is running.
For ubuntu server images, the awk interpreter being used is gawk (GNU awk) while on desktop images, mawk is the default interpreter installed.
ppa-purge on ubuntu versions that use the deb822 source format (Noble and Mantic) uses the -i option in awk which is only available in gawk and is missing in mawk. This results in the following error:
awk: not an option: -i
A proposed fix would be to replace awk with sed.
[Reproducer]
1- install a desktop version of Noble or Mantic. In this case Noble is used as an example
2- add a ppa: $ sudo add-apt-repository ppa:oibaf/
3- upgrade to the version of the packages included in the ppa: $ sudo apt update && sudo apt upgrade
4- install ppa-purge: $ sudo apt install ppa-purge
5- ppa-purge version: $ dpkg -l| grep ppa-purge
ii ppa-purge 0.2.8+bzr63-
6- run ppa-purge: $ sudo ppa-purge ppa:oibaf/
7- you will see the following output with an awk related failure (only a sample of the output is shown below):

8- this results in the packages not being downgraded since the .sources file was not disabled.
[cause]
This was caused in a patch that tried to fix LP:2036761
Although this patch was successful in fixing Ubuntu server installs, it does not work for Ubuntu desktop installs where gawk is not installed by default.
[workaround]
Manually install gawk: $ sudo apt install gawk
[solution]
I have written a patch that replaces the awk command with the sed command.
Below is the test plan showing the fix
[Test Plan]
1- Install the new ppa-purge version:

We can see that gawk is being pulled in as a dependency
2- verify the ppa-purge verison:
ghadi@ghadi-
ii ppa-purge 0.2.8+bzr63-
3- verify that gawk is also installed: dpkg -l | grep gawkii
gawk 1:5.2.1-2build3
4- run ppa-purge again on the ppa installed in the [reproducer] section:

5- we can see that packages were successfully reverted.
[Where problems could occur]
- the sed command might fail to disable the ppa causing ppa-purge to not downgrade the packages
