Package: x2goclient Version: 4.1.1.1
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.
Client OS Ubuntu 18.04.3 LTS with libssh-4 0.8.0~20170825.94fa1e38-1ubuntu0.5 Server OS Ubuntu 16.04.6 LTS
Since december, 10th on Ubuntu, every time I connect to a server with either file sharing or printing enabled I have this error message : "Cannot create remote file ~ilm/.x2go/ssh/key.jdT502" - "SCP: Warning: status code 1 received: scp: ~ilm/.x2go/ssh: No such file or directory\n" But the directory does exist.
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
A similar issue is handled for Windows in SshProcess::start_cp()
As a workaround I reinstalled an old version of the libssh-4 package and the bug went away.
