I recently installed a Samsung 970 EVO NVMe M.2 drive on my Gigaybyte Z390 UD motherboard. My OS is Ubuntu 16.04.6. The drive is recognized by the BIOS and shows up (as nvme0n1) when I execute the lsblk command, but it has no mount point, and I can’t access it. I have spent too much time looking for an answer on the internet, but most proposed solutions don’t work. What can I do to correct this situation?
