Certificate verification failed The repository does not have a Release file

Hi, there

I’ve met issue during installation v4, one week ago I didn’t face such problem.

The repository ‘Index of /packages/4.x/deb/ stable Release’ does not have a Release file

I suppose something might be wrong with certificate “Err:4 Index of /packages/4.x/deb/ stable Release
Certificate verification failed: The certificate is NOT trusted. The certificate chain uses expired certificate. Could not handshake: Error in the certificate verification. [IP: 443]”

Same problem recently noticed with v3 installation on focal too (as dicussed here: Chirpstack network server installation - #7 by robk).

I’ve just tried updating both v3 and v4 on focal without issues…
