In an Ubuntu 18.04 virtual machine in VirtualBox, I could define a Shared Folder like so: And then mount it like this: mount -t vboxsf Projects -o uid=1000,gid=1000 /home/fboender/Projects/ Or with the equivalent fstab entry like this: Projects /home/fboender/Projects/ vboxsf defaults,uid=1000,gid=1000 0 0 This fails on an Ubuntu 20.04 guest with the following error: /sbin/mount.vboxsf: [ ]

For example: install () { # Install sla # Install sla to $PREFIX (/usr/local by default). # # You can specify the prefix with an environment variable: # # $ PREFIX=/usr sla install # Set the prefix PREFIX=${PREFIX:-/usr/local} [ ]
