also tested it on a Ubuntu Trusty (18.04) system. It does not work there yet!
Thanks for testing. Oh, that's right. For Ubuntu, I've only built release/stable KDrive packages for Jammy (20.04), Kinetic, Lunar and Mantic.
Unfortunately, X2Go Server always hard-depends upon KDrive, so any older version that will not get KDrive packages will be broken.
I can fix that (by removing KDrive support for old deb-based distro versions), but will only be able to make a new X2Go Server release next week.
On a related note, I'm pretty sure that KDrive at least compiles on 18.04, but given that 18.04 is freshly out of mainstream support, I'd rather rely on commercial support requests for providing binaries for older distros such as 18.04, if there's even any interest.
