I occasionally dabble in Ubuntu and do it primarily through a virtualbox VM running on my main Win10 system. I've been using the same image for a couple of years now with only minor updates for new patches to Virtualbox and recommended updates within Ubuntu.
Last night I went to do something that involved accessing a shared drive from the host system mapped into Ubuntu and it wasn't working. Further investigation revealed that while Virtualbox could still see the shared drive, it wasn't showing up in Ubuntu. Tried removing and recreating the shared mapping to no avail. Any ideas what might have caused this? It literally just stopped working between one day and the next and I don't recall installing any patches or updates to Virtualbox or Ubuntu. --------- Brian
