[X2Go-User] Fedora 24 Connection failed. /usr/bin/perl: symbol lookup error: /usr/local/lib64/perl5/auto/DBI/DBI.so: undefined symbol: Perl_xs_apiversion_bootcheck

[Robert Dinse]

      For what it is worth, I just did a fresh install of Fedora 24 and a fresh
install of x2go server and a fresh install of mate.  I can not get x2go to work
so far.  It gets up to where I get the black screen and hangs.

I got a hint from this thread: http://stackoverflow.com/questions/7777252/uninstall-all-perl-modules-installed-by-cpan <http://stackoverflow.com/questions/7777252/uninstall-all-perl-modules-installed-by-cpan>

For example, I upgraded from Fedora 22 to Fedora 23 and the Perl version changed. All modules installed previously via cpanm into /usr/local/lib64/perl5did not work any more and prevented me from using cpanm.
