After spending some time on installing and reinstalling Univention 5.0 on Proxmox here is what I get.
Fresh install. Running and reachable from LAN and WAN through https:// with letsencrypt (2.0.0-1).
Trying to install Nextcloud gives me:
Installation of Nextcloud Hub We tried to do as requested but failed for nextcloud on my.dom.aine These are the error messages from the server. More information might be available on the system's logfile /var/log/univention/appcenter.log

Force Execute changes anything.
Did anyone experience the same probleme?
PS: While installing Let’s Encrypt Certificate there something not clear to as well:
3. Once the certificate has been configured, you need to restart the desired services via the "System services" module in the UMC. This is only required during setup. The automatic renewal mechanism restarts the services if needed. If you want to change the hostname in the certificate later on, just change the configuration in the App Settings and save.
Which are the desired services? -> apache2 ? Not knowing I just restarted the server. I did as well a
update-ca-certificates as root in command.
