Package: x2goserver
Version: 4.1.0.4
Tags: rpm-packages

Various openSUSE Tumbleweed packages for the X2Go server are built in
such a way that they require Perl 5.28.1. However, Tumbleweed no longer
distributes that version of Perl; it now distributes only Perl 5.30.1.
This means that it is impossible to install these X2Go server packages
on the most recent release of Tumbleweed, and for Tumbleweed systems
where those X2Go server packages were already installed, it is
impossible to upgrade Tumbleweed without removing the X2Go server:

Simply telling zypper to keep the obsolete packages doesn't work as
this ends up in a rabbit-hole of seemingly irresolvable dependency
issues.
