When enabling Livepatch from Canonical Livepatch Service, I followed the instructions and pasted the commands in terminal:

$sudo snap install canonical-livepatch

that was OK

$sudo canonical-livepatch enable ###my key number###

system_key.go:120: cannot determine nfs usage in generateSystemKey: cannot parse /etc/fstab: expected between 3 and 6 fields, found 8

Any easy directions on that?

What is the output of

cat /etc/fstab

(you are free to obfuscate Information that you want to keep secret, as Long as the gist of the contents stays readable)

Good call, here's the out put:

UUID=nnnfnnd-nncb-nenn-abaf-nnnnndnnnncd / ext4 defaults 0 0
/swap.img none swap sw 0 0
tmpfs /run/shm tmpfs defaults, noexec, nosuid 0 0 #edit note

I assume that the error is in the last line. There must not be space characters between the options.

edit the /etc/fstab file and change the last line into

tmpfs /run/shm tmpfs defaults,noexec,nosuid 0 0

The Canonical livepatch service isn't part of Launchpad. I think the right place to file bugs on the livepatch client is

(Having said that, Manfred is likely right - but I'd like to encourage filing things against the right project rather than against Launchpad itself.)

Dear Manfred, I assume it worked, since I got the output:
Successfully enabled device. Using machine-token: <id>

Colin, I totally agree. Since the problem is solved I will let as it is, next time I will make sure to send it to livepatch.
Thank you.
