Image mounting disabled: TEST FAILED: guestmount is missing (libguestfs-tools)

I use the latest docker-image and while starting it up I get the following message:

Image mounting disabled: TEST FAILED: guestmount is missing (libguestfs-tools)

can I do anything about this or is this intentionally ?

I do not want to apt-install it by hand because with an update it’d be gone :wink:
Perhaps it’s just missing in the build ?

I get the error in

uroni/urbackup-server:latest-zfs

sha256:b2d139b48f985eb71779f1c740ebb1fe009fcccb366a2cb12f7ab834582ab513

and

uroni/urbackup-server:latest

sha256:29cf74482d2de8781e41384464b5a9884e57b881203dc14e7718f24b44e517fe

I’m deploying urbakup in truenas scale and I’m getting the same error.
@uroni is this normal? or should we report it as a potential bug?

Hello @uroni! Is it possible to fix this, add to installation? It’s in Docker container as well.

Is it possible to use alternative: qemu-nbd

@artyomtsybulkin I myself started to question if this issue (or any other issue for that matter) will ever be resolved.

I know. It’s relevant. Actually problem is that this package not included to docker images. But in addition it’s very unstable after all.
