i installed a new ucs 4.3.3. After installing these APPs:
Kopano, Kopano Webapp, Z-Push, Benno-Mailarchiv, Nextcloud and the last OnlyOffice

i cant install more APPs. If i whant to install the APPs through shell, i get this:

root@sv01:~# univention-upgrade

Starting univention-upgrade. Current UCS version is 4.3-3 errata410

Checking for local repository:                          none
The connection to the repository server failed: Configuration error: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:661). Please check the repository configuration and the network connection.

I tested it with apt to:

root@sv01:~# apt update
File: /etc/apt/sources.list.d/15_ucs-online-version.list
# An error occurred during the repository check. The error message:
Paketlisten werden gelesen... Fertig
E: Problem executing scripts APT::Update::Pre-Invoke 'grep -Fqs '# An error occurred during the repository check.' /etc/apt/sources.list.d/15_ucs-online-version.list && ucr commit /etc/apt/sources.list.d/15_ucs-online-version.list ; ! grep -F '# An error occurred during the repository check.' /etc/apt/sources.list.d/15_ucs-online-version.list'
E: Sub-process returned an error code

How could i fix this?





it might be an issue with your license- have you installed your license file?

Otherwise try to re-create it manually:
ucr commit /etc/apt/sources.list.d/*




I found the Solution

type in shell


after that, the problems are gone


Same issue. Same solution. Thx
