From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Disabling a systemd service won't prevent it from starting. For example, if another service depends on it then it will start anyway.
You have to mask the service which redirects the service files to
/dev/nullso that the service effectively has zero directives.systemctl mask --now snapdIt also means that anything which depends on snapd will likely fail. That is absolutely an improvement since we obviously don't want anything that depends on snaps.
What’s wrong with just removing snap? When ever I am forced to install Ubuntu I will remove snap and the “advantage-tools” (the part trying to sell you support)
First I’ll
snap remove —purgeall snap packages Thenapt purge —auotoremove snapd ubuntu-advantage-toolsLeaves behind a bunch of stuff. You have to manually remove each Snap individually, plus the snapshots they take and then hide, and then use Snap to remove itself (it doesn't let you), then you can apt purge snapd.
There's several levels of "we know better than you so we'll just keep this here for when you inevitably change your mind" and it is exhausting.
I don't even know if the above would also clean up all the dev/loop cruft. It was an unpleasant surprise to discover that apt remove alone didn't at least disable all the systemd .mount units.
There’s like one directory left after my uninstall - I don’t do this by hand though so I’ll have to look up the playbook.
My first line was the snap remove
Might need an
autoremove —purgeat the end to clean up.
