Snap is not working(cannot determine nfs usage in generateSystemKey: cannot parse /etc/fstab: expected at least 3 fields, found 1)

Ogra asked for the output of snap change 13 and snap change 15; this would show output about what happened in those changes and what failed, perhaps why.

Also, formatting;

when I ask for snap change 13 I get an error message: cannot find change wit id “13”

dilyn · July 16, 2025, 1:15pm

Ah. Because it fell of the list. snap change 16 and snap change 17 would be fine enough.

Does my /etc/fstab still contain errors or not?

ogra · July 19, 2025, 9:59am

Hard to tell since you didn’t post all of it, the “right side” is cut off, so we can not see the rest of the lines for your root filesystem (first “UUID” entry) or the swapfile line and wether it has the correct number of arguments…

Do you still get any fstab related errors? Else it is something else…

Lambert57 · July 19, 2025, 11:43am

‘’'# /etc/fstab: static file system information.

Use ‘blkid’ to print the universally unique identifier for a

device; this may be used with UUID= as a more robust way to name devices

that works even if disks are added and removed. See fstab(5).

Both lines are still cut off (as you can see by the > sign that indicates the line is continued if you scroll sideways) … try to use the cat command to output the file before copy/paste, that should print everything …

I also note that you are using three single quotes ‘’’ instead of three backticks ``` in your paste, that will not fix the formatting, please use backticks (if you do not know where to find them on your keyboard, just copy/paste them from my post )…

regarding the core22 error, try to run

sudo snap disable core22

and

sudo snap enable core22

seems the original fstab issue somewhat confused the whole snapd database, perhaps disabling and enabling the snap makes it found …
