[SOLVED] Problem with proxmox-backup-client in LXC contianer

I have a Debian 11 turnkey linux fileserver running as LXC container under ProxmoxVE8. I backup the data with proxmox-backup-client to a remote PBS3 datastore, which seems to work without problems.

Login to PBS and following works:
proxmox-backup-client snapshot list --ns "$PBS_NAMESPACE" storing login ticket failed: $XDG_RUNTIME_DIR must be set +========================================+=============+========================================+ | snapshot | size | files | +========================================+=============+========================================+ +----------------------------------------+-------------+----------------------------------------+ | host/ct-file-srv1/2023-10-18T04:37:01Z | 641.24 GiB | catalog.pcat1 dataroot.pxar index.json | +----------------------------------------+-------------+----------------------------------------+ | host/ct-file-srv1/2023-10-19T04:37:01Z | 641.249 GiB | catalog.pcat1 dataroot.pxar index.json | +========================================+=============+========================================+

When trying to retrieve the catalog of these backups I get erro rmessages I cannot make sense of:
proxmox-backup-client catalog dump host/ct-file-srv1/2023-10-19T04:37:01Z storing login ticket failed: $XDG_RUNTIME_DIR must be set Error: unable to read "/mnt/datastore/datastore1/host/ct-file-srv1/owner" - No such file or directory (os error 2)

I get the same message when I try to open a interactive shell:
proxmox-backup-client catalog shell host/ct-file-srv1/2023-10-19T04:37:01Z dataroot.pxar
On the PBS there is an owner file in:

Can anyone give me a hint please ?
After looking at it nicely written down, I saw that I should also add
to my other commands, which now solved it. Thanks for watching ;-)
