Comment 4 onkobu 2022-08-29 08:49:28 UTC
Emerge installed 2.4.2-r1 that complains constantly with:

Unable to encrypt connection: Unable to create server credentials.

/etc/cups/ssl exists and is filled (owner is root:lp with permission 700, inside .crt and .key files. Keys have permission 600, certs have 644.). It worked before even with FQDN in a local network. I also switched LogLevel to debug but that didn't spool out more details. USE is (and was) ssl and openssl. There is no certificate auto generation anymore on that host.

Is that related somehow?
Comment 5 onkobu 2022-08-29 09:31:56 UTC
Changing USE to not contain openssl fixes the issue and certificates are created again.
