Currently running server 2.3.8 on Debian 10 with libguestfs 1.34.6-2 with ZFS storage and urbackup running as root.
All of the images fail when you first click the mount button with an error “Guestmount”. However, if you click back and then select the same image again, the file list will appear and you can select files to download.
On one specific image, whenever I click mount I get the following error:
ERROR: Image mounting failed: Guestmount...
libguestfs: error: mount_options: /dev/sda on / (options: 'ro'): Failed to read last sector (5859106814): Invalid argument
HINTS: Either the volume is a RAID/LDM but it wasn't setup yet,
or it was not setup correctly (e.g. by not using mdadm --build ...),
or a wrong device is tried to be mounted,
or the partition table is corrupt (partition is smaller than NTFS),
or the NTFS boot sector is corrupt (NTFS size is not valid).
Failed to mount '/dev/sda': Invalid argument
The device '/dev/sda' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
guestmount: '/dev/sda' could not be mounted.
guestmount: Did you mean to mount one of these filesystems?
guestmount: /dev/sda (ntfs)
Guestmount with dev /dev/sda

Mounting via the cli works fine with urbackup_mount_helper.
