Hello, After the Virtualbox update from the version 5 to version 6 series: * Invoking copy/paste operations when shared clipboard is turned on causes the guest machine to immediately abort * Even with shared clipboard turned off in Virtualbox settings, guest machines generate an Abort status in Virtualbox during a normal shutdown * /var/log/messages indicates a segmentation fault in Virtualbox shclipboard application * These aborts do not occur when running Virtualbox over a ssh-X tunnel I'm wondering if this is related to the older nx-libs problem with shared clipboard submitted by mikedep333. x2go client: v 4.1.2.2 (Qt 5.15.2) running on Fedora 33 x2go server: : 4.1.0.3, nxproxy 3.5.99.26 John.
