mountpoint not exists

Error message

mountpoint not exists

What it means

Guard in RetrieveMountpointByUser: a mountpoint was derived from the user's home directory (prefix before '/home/', defaulting to '/'), but FileExists reports that path does not exist on disk. The computed storage root is therefore invalid and the function returns an error instead of a bogus path.

Solutions

1. Check whether the derived mountpoint path was unmounted or deleted on the host
2. Verify filesystem mounting at boot (fstab entries) for the volume in question
3. Handle the '/' default case explicitly if the storage root is legitimately elsewhere
4. Retry after restoring the mount, since the path may reappear once mounted
