Unknown error when trying to mount ISO with file manager

I’m on XFCE.
I’m trying to mount Proxmox VE ISO installer:

I download and verify the ISO, then right-click and “Open with iso mounter”

A ghostly icon with the ISO device appears, but when clicking it I get
“unknown file system…”
(sorry, I don’t remember the exact word)
And then I cannot get rid of the ghostly icon because since it’s not mounted I cannot unmount.
I need to reboot to get rid of the icon.

Can someone with XFCE, or even any other DE, try to mount this ISO via file manager?

Thanks.

If you have Packman enabled
Install isomaster

Mount:

sudo mkdir /mnt/proxmoxiso
sudo mount -o loop /path/to/proxmox-ve_9.0-1.iso /mnt/proxmoxiso/

Unmount:
sudo umount /mnt/proxmoxiso/

Solved.

For some reason the Proxmox ISO uses hfsplus filesystem, so I need to temporarily enable the driver:

Thanks.

The case of the ISO that wasn’t one :rofl:
