Mount Partitions Via /etc/fstab

[agent_kith]

I have been using a M.2 SSD on my Intel NUCs for a few years now with no problems. SnakeOil will always mount a disk that Ubuntu recognises. Have you tried checking whether the SSD is working just with standard Ubuntu?

And please provide more details of the hardware that you are using. And make sure the SSD is the SATA version

What kernel are you using? If you're using the old Snakeoil custom kernels, you'll need to pick the one with nvme support.

Otherwise, you'll need to modify /etc/fstab directly to mount your nvme partition.
