I do not think the problem is on the host side. I have set a shared folder with the path and the folder name. I do not have Read-only checked and I do not have Auto-mount checked but I do have Make Permanent checked. And I think it works because when I launch the guest machine and open the file manager (called "Files"), it shows under "+ Other Locations" a list of several items under "Networks". But "VIRTUALBOX (File Sharing)" is repeated twice which suggests to me there might be something wrong that I need to fix. So, what is wrong that I need to fix?
The items listed under Files -> +Other Locations -> Networks are:
- VIRTUALBOX (File Sharing)
- Window Network
- DESKTOP-REDACTED
- READYSHARE
- VIRTUALBOX (File Sharing)
An instructional video on youtube says that in order to have a shared folder between a ubuntu guest and its host, you need to have a group called "vboxsf" that is generated automatically somehow with VirtualBox. But this does not seem to be the case:
worker@virtualbox: $ whoami
worker
worker@virtualbox: $ sudo adduser worker vboxsf
[sudo] password for worker:
adduser: The group ''vboxsf' does not exist.
