I proceeded with the reinstall even though the remove of cache files above did
not work.

$ sudo snap install canonical-livepatch
canonical-livepatch 10.5.4 from Canonical? installed

$ sudo pro enable livepatch
One moment, checking your subscription first
Canonical livepatch enabled.

So I chcecked again:

sudo ls -la /home/bosse/snap/canonical-livepatch
ls: cannot access '/home/bosse/snap/canonical-livepatch': No such file or
directory

and

$ sudo ls -la /home/bosse/snap/
total 12
drwx------  3 bosse bosse 4096 Apr 18 07:58 .
drwxr-xr-x 26 bosse bosse 4096 Apr 18 08:16 ..
drwxr-xr-x  4 bosse bosse 4096 Jan  8 18:13 lxd

So here is no directory canonical-livepatch at all...
And therefore no files or links therein either...
There's just the dir "lxd"
