debian 10 VM: "Unable to init server: Could not connect: Connection refused."

[qubes...@riseup.net]

Hi,

Since today I'm unable to start any GUI application (testing with gnome-terminal and xterm) within a debian 10 based AppVM:

In Qubes Manager the VM shows the green state icon.

To collect logs I connected via 'xl console':

sudo xl console debian-10:

journalctl -f

<try to start gnome-terminal>

Log output:

qrexec-agent[599]: executed user:QUBESRPC qubes.VMShell dom0 pid 24766
qrexec-agent[24766]: pam_unix(qrexec:session): session opened for user user by (uid=0)

The last updates according to /var/log/apt/history.log within that VM:

Any help to further debug or solve this issue is greatly appreciated.
