Hello ,
The following is showing on my server on /etc/apt/sources.list.d :
15_ucs-online-version.list
20_ucs-online-component.list
# An error occurred during the repository check. The error message:

Of course this files are important to do any kind updates or upgrades against your servers. Please advice on what commands to run to regenerate the sources list for both files.

repository/mirror/version/end: <empty>
If the mirroring of the repository is active (see 'repository/mirror'), this variable is set each time to the UCS version which was last retrieved from the mirror.
repository/mirror/version/start: <empty>
If the mirroring of the repository is active (see 'repository/mirror'), this variable configures the lowest UCS version which is retrieved from the mirror.
version/erratalevel: 364
Four types of UCS updates are differentiated: Major releases (released approximately every four years, may introduce bigger changes), minor releases (released approximately every 6-8 months, error corrections and new functions), patch level releases (released every 2-3 months, less changes compared to a minor release, focus on bugfixes) and errata updates (timely bugfixes for security problems and critical bugs). This variable is set automatically during updates and contains the version of the installed errata updates.
version/patchlevel: 4
Four types of Univention Configuration Registry updates are differentiated: Major releases (released approximately every four years, may introduce bigger changes), minor releases (released approximately every 6-8 months, error corrections and new functions), patch level releases (released every 2-3 months, less changes compared to a minor release, focus on bugfixes) and errata updates (timely bugfixes for security problems and critical bugs). This variable is set automatically during updates and contains the version of the installed patch level release.
version/releasename: Walle
This variable contains the codename of the UCS release.
version/version: 4.0
Four types of UCS updates are differentiated: Major releases (released approximately every four years, may introduce bigger changes), minor releases (released approximately every 6-8 months, error corrections and new functions), patch level releases (released every 2-3 months, less changes compared to a minor release, focus on bugfixes) and errata updates (timely bugfixes for security problems and critical bugs). This variable is set automatically during updates and contains the version of major and minor update.

your system is unable to contact the Univention update server and its repository. The error message is “host is unresolvable” which points to DNS. Let’s check if your system can resolve and reach the update server at all. Would you please execute the following commands and paste the output here:
even if you replace the files with a working copy from someone else chances are they’ll get overwritten again soon if the underlying problem isn’t fixed. So let’s debug this some more.
Can you please post the output of the following commands:
Additionally please run the following and attach the resulting file “/tmp/trace.txt” to this post: “strace -s 1000 -tt -f -o /tmp/trace.txt ucr commit /etc/apt/sources.list.d/15_ucs-online-version.list”
If the “strace” tool is not installed then download it manually from here, copy it to the server and install it with “dpkg -i strace*deb”.
The problem was resolved by the kind of help of Americas representative.

As for the details:
A UCS update is divided into multiple parts: A pre update script, the update
itself and a post update script.
On the server the pre update script for UCS 4.1 was already applied in parts,
but then canceled. This resulted in the server being already set to use an
encrypted connection for the update, but at the same time to a host that
didn’t support encrypted connections.
The issue could be easily resolved by setting the server to the new value and
unsetting the port:
ucr set repository/online/server=updates.software-univention.de
ucr unset repository/online/port[/quote]
according to rriley recommendation I am getting following:
File: /etc/apt/sources.list.d/15_ucs-online-version.list
# An error occurred during the repository check.
The error message: E: Problem executing scripts APT::Update::Pre-Invoke 'grep -Fqs '

E: Sub-process returned an error code
