Seems to be working, thanks!
In the meantime, I’ve got another one that may be a real issue, after system suspend:
Mar 13 02:40:42 host sdwdate-start-anondate-set-file-watcher[3785]: /usr/sbin/anondate: ERROR: Variable 'vstart' is empty or contains only whitespace/newlines.
Mar 13 02:40:42 host anondate[3849]: /usr/sbin/anondate: ERROR: Variable 'vstart' is empty or contains only whitespace/newlines.
full output: https://openqa.qubes-os.org/tests/132359/file/suspend-whonixcheck-sys-whonix.log
And if you’d need full jourrnal of sys-whonix, it’s in https://openqa.qubes-os.org/tests/132359/file/suspend-var_log.tar.gz (log/xen/console/guest-sys-whonix.log file)
