[Bug 1970449] Re: GPG keys are not shown in Software and Updates

[Heiko Hösch]

Here is a working version of the AptAuth.py for Ubuntu 22.04.

The testing version of Ubuntu might have another software-properties-
version.

I just changed the subprocess.run to subprocess.Popen and added a p.close to end the subprocess
where it reads the keys. I left the rest as it is. I did not want to change more than necessary.

Other methods of this class use subprocess.run, there you don't need to end the subprocess, I would
say. The subprocess.run ends the subprocess automatically, I would say, but the subprocess.Popen
seemingly needs a manual closing of the subprocess.
