I'm new to Ubuntu, but not new to Linux. I've installed Xubuntu 18.04 to check it out, and I'd like to mount some of my NAS shares. I've added appropriate lines to /etc/fstab, but so far I've been unsuccessful.
On other systems, nfs-common or nfs-utils is required, but so far I haven't been able to find a software manager that will install either one.
Does anyone here know what I'm missing?
