Error when using Wyng with rclone

[ldeso]

In Qubes OS, the command wyng send --all fails with "CalledProcessError" if the destination is a remote filesystem mounted with rclone:

Traceback (most recent call last):rivate.img
  File "/usr/local/bin/wyng", line 4644, in <module>

subprocess.CalledProcessError: Command '[['/usr/bin/qvm-run', '--no-color-stderr', '--no-color-output', '-p', 'sys-backup', '/bin/sh /tmp/wyngrpc/tmpx4p86e2_']]' returned non-zero exit status 1.

This is because of an error when Wyng tries to execute the script /tmp/wyngrpc/tmpx4p86e2_ on the qube where the destination is mounted. This script is:

trap '' INT TERM QUIT ABRT ALRM TSTP USR1
set -e && export LC_ALL=C
 cd '/mnt/remote/qubes-rclone.backup' && mv -T Vol_8ce480/S_20230922-102839-tmp Vol_8ce480/S_20230922-102839 && mv Vol_8ce480/volinfo.tmp Vol_8ce480/volinfo && mv archive.ini.tmp archive.ini

When executing this script manually, this error happens:

mv: cannot move 'Vol_8ce480/S_20230922-102839-tmp' to 'Vol_8ce480/S_20230922-102839': File exists

For some reson, there is an empty directory on the remote with the name Vol_8ce480/S_20230922-102839 that prevents Wyng from running the command mv -T Vol_8ce480/S_20230922-102839-tmp Vol_8ce480/S_20230922-102839.

This only happens when mounting the remote filesystem with rclone, it does not happen when using e.g. davfs2.

Environment: Qubes OS 4.2.0-rc1, Wyng 0.8beta release 20230826
