Control: reassign -1 x2goclient 4.1.2.1 Control: forcemerge -1 1428
SSH key fails to be copied to the remote side because the path use a tilde, so neither file sharing nor client-side printing works. [...] After using gdb I saw that ONMainWindow::exportDirs() calls SshMasterConnection::copyFile() with dst="~"+uname +"/.x2go/ssh/"+dst; which is ultimately passed to libssh. But following CVE-2019-14889 the path is now literal (quoted), see https://git.libssh.org/projects/libssh.git/log/src/scp.c for the libssh logs and https://usn.ubuntu.com/4219-1/ for the ubuntu packages
Yes, I think that this change has been intentional. I'll have to fix that in X2Go Client and I know how to do this easily to retain support for pre-patched and patched versions.
I will, however, probably not be able to provide new release versions with that fix (and others) for about a months.
I'll let you know when fixed nightly versions are available, though.
As a workaround I reinstalled an old version of the libssh-4 package and the bug went away.
Please don't do that OR recommend that. You're essentially now running without the CVE fix, which is probably worse than a broken client.
