ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:997) what's this about? I'm not a pythonista but I'd look into that, maybe your network settings?

I’ve seen a similar error in other contexts. For example, I have a setting in my .gitconfig that disables certificate validation for one of my employer’s internal servers.

Whatever the problem, it doesn’t affect apt when it accesses other servers.

I know next to nothing about certificate validation, so I have no clue what might be broken, but I wonder if, on this version, removing snapd or Firefox might remove/break some certificate thingy.

I don’t know if it’s possible to install two WSL instances running the same distribution. If it is, I could test if the add-apt-repository works before I remove anything.
