I tried installing the additions from the official media, as suggested, rather than the distribution dependent packages.
The installation succeeded, but had no effect on my problem.
I reviewed the logs for the systemctl unit associated with the fstab entry, and discovered the following message:
Code: Select all
/sbin/mount.vboxsf: shared folder 'home' was not found (check VM settings / spelling)
I can mount the share using the mount command, even without the share name, which proves that the fstab entry is valid, but some problem occurs in the systemctl unit responsible for mounting the share.
It is quite frustrating, because I attempted changing this name, deleting the entry in the VM and re-adding it, rearranging the order of entries in fstab, and similar variations. The effect is always the same. The other shares mount, but this one does not. I can think of nothing exceptional about it.
I tried looking in the VM definition file (.vbox) but saw no entries for the shared folders. I was hoping to find some strange serialization for the options, which might affect the operation of the VM, but now I am simply wondering where these entries are saved. Somehow they are persisted, but not in the natural location.
