The first time that I put my Librem 5 USA (Liberty) online, the first action I did was to open Terminal app to run:
sudo apt-get update
But the first time that I ran the command, it gave a ton of errors indicating that
Certificate verification failed: The certificate is NOT trusted. The certificate chain uses expired certificate. Could not handshake: Error in the certificate verification. [IP: 126.96.36.199 443]
Then, I ran the command a second time and it worked fine.
Is this any kind of security issue or is this expected? Was my device just slow to refresh a certificate cache?
