proxmox-backup-client mount not work on centos 7

[marwen]

Hey guys.

I try to mount a snapshot/backup

proxmox-backup-client mount host/backuppc/2021-03-12T06:26:16Z root.pxar /mnt/mountpoint --repository filebackup@pbs@10.124.0.195:8007:QNAP-PBS-NFS

on debian 10 it works perfect (fuse-lib 3.4.1)

on centos 7 i get an error message with the same command.

proxmox-backup-client mount host/backuppc/2021-03-12T06:26:16Z root.pxar /mnt/mountpoint --repository filebackup@pbs@10.124.0.195:8007:QNAP-PBS-NFS

any idea to fix that ?

Hi,
this is probably not related to the fuse library as I have an ArchLinux system with Fuse 3.10.2 and proxmox-backup-client 1.0.10 and mounts are working just fine.
This seems more like a bug of the outdated version of the proxmox-backup-client in the github repo.
The error is related to the tokio runtime. You could try to build a newer version of the client, have a look at the AUR package in order to understand what steps need to be taken to compile the client by yourself.
