Snap automatic updates can now be disabled with $ sudo snap refresh --hold
.
This can be seen in this other thread and this blog post and from the mouth of the horse itself.
My Ubuntu 22.04 is up to date but I get an error when running the command. Any idea why?
$ sudo apt update
...
All packages are up to date.
$ sudo snap refresh
All snaps up to date.
$ sudo snap refresh --hold
error: unknown flag `hold'
