osmo-upf fails to start since https://gerrit.osmocom.org/c/osmo-upf/+/31165 was merged in the Osmocom-repo-install-debian11 and Osmocom-repo-install-centos8 jobs:

The kernels versions are 4.18.0-425.3.1.el8.x86_64 (CentOS 8 / AlmaLinux 8) and 5.10.0-9 (Debian 11). It does work on my Ubuntu 22.04 install with a 5.15 kernel. So my guess is, that it's related to the kernel.

I suspected that maybe it works if changing osmo-upf to osmo_upf in the table name (reading the man page it seems the minus character is not allowed as identifier?). But that did not help it.

I'll disable checking this service until this is fixed (or maybe we don't care about older kernels?), so we see when the tests fail for other reasons.
