Having a "PostUp" section in wireguard config crashes container

[wnhre2ur8cxx8]

I am not 100% sure I have this analyzed correctly. Anyway, I need to execute a script everytime my connection gets established, si I figured I would use the wireguard config for that and added a PostUp section. It seems to execute it and then do something with iptables and then crash.

ehwn I take the section out, it just runs and works.

Aha, immediately after I wrote the issue I figured it out.

python3 is not installed at this point apparently. So i need to start it properly, let it install itself and then restart it with the changed wireguard config.

I guess it makes sense to install python after the VPN connection ist established, so I dont know if there yould be a way for you to fix this..
