Everything was OK for me to upgrade to 5.2 except keycloak, I just need it for nextcloud, bur anyway,
I installed Keycloak for compatibility to upgrade to 5.2 but the install failed and I have lose the web interface, because apache2.service do not start because of a missing certificate.
I tried to generate the missing certificate with this
univention-certificate new -name ucs-sso-ng.domain.pf
Now I’m stuck
the /var/log/apache2/error.log says
[Thu Mar 06 10:05:19.805750 2025] [ssl:emerg] [pid 1356] AH02572: Failed to configure at least one certificate and key for ucs-sso-ng.domain.pf:443
