In 19.04 I had removed all of the snap applications, and installed regular code versions of these same applications.

I upgraded to 19.10 and it reinstalled all of the same snap applications! This can be seen as the various /dev/loop[1-8] devices...

Any idea why Ubuntu insists on (re)installing snap applications? Don't they delay boot times? What makes these snap applications better?

  • From what little I have read, snaps are better for the developers since one snap is good for multi versions. Don't know if they are better for us yet.

    I'm seeing three separate questions: Why do snaps get (re-)installed? Do snaps delay boot? How are snaps different from debs? Each seems worthy of a separate thread. I downvoted because each question currently seems opinioned instead of neutral. Happy to revisit.

    @user535733 thanks for coming forward, and for identifying why the down vote.

Look at the manifest. It specifies all the snaps and snap-associated packages that would be installed.

gir1.2-snapd-1:amd64    1.49-0ubuntu1
gnome-software-plugin-snap      3.30.6-2ubuntu10
libsnapd-glib1:amd64    1.49-0ubuntu1
snapd   2.41+19.10.1
snap:core       stable  7917
snap:core18     stable  1223
snap:gnome-3-28-1804    stable/ubuntu-19.10     71
snap:gnome-calculator   stable/ubuntu-19.10     501
snap:gnome-characters   stable/ubuntu-19.10     317
snap:gnome-logs stable/ubuntu-19.10     81
snap:gtk-common-themes  stable/ubuntu-19.10     1353

The fact that you deleted them in 19.04 shouldn't have affected what's installed in 19.10 but that doesn't seem to be the case.

In 19.04, if you run sudo apt purge snapd, doing so would remove, in addition to snapd, the snaps presently installed on your system. Now, if you run sudo do-release-upgrade, neither snapd nor any snaps are installed. Two users, here, and here, have verified this. I also checked, in a VM, that the upgrade from 19.04 to 19.10 didn't reinstall snaps or snapd, if sudo apt purge snapd was run before sudo apt purge snapd.

Whether this situation will persist if users eventually upgrade from 19.10 to 20.04 is unclear.

However, there's a comment over at discourse.ubuntu.com worth reading. Quoting from there:

This just sounds like a feature request in the upgrade tool. Essentially if the user has already removed a snap, and installed the deb of the application, then an upgrade happens they get a thing back that they removed.

However, I’m not sure the upgrade tools have the intelligence to know that you previously removed the snap, and don’t want it back. Further, the point of the upgrade tool is to take you to the new release. Those snaps are part of the new release. I have a feeling if you removed firefox from 19.04 and upgraded to 19.10, you’d get firefox back. Which is a similar use case that you’re describing.

That comment indicates that snaps should be reinstalled which isn't what we, who purged snapd see.

(I would also point out that before upgrading to 19.10, I purged several fonts I don't need. They too were not re-installed.)


What makes these snap applications better?

Martin Wimpress is the new Desktop Director of Ubuntu. He talks about the rationale behind snaps in this video: Future of Ubuntu & Unpacking Snaps with Martin Wimpress | Part 2 | IG Talks ep. 4.

  • I have a VM currently running 19.04. I completely removed snapd and then ran sudo do-release-upgrade. These are the packages that'll be installed/removed/updated once the upgrade starts. I can't find the reference for snapd although libraries are to be upgraded and one of them recommends snapd.

  • I haven't tried doing an actual upgrade. That was the list of packages on which some action would be taken once the upgrade starts.

  • @Kulfy - I did the upgrade, after removing all snaps and snapd, and they were not reinstalled. Maybe the key is to remove snapd. Nov 6, 2019 at 16:34
  • @ajgringo619 very interesting! Perhaps OP will mention if snapd was also removed or not. It would be worth asking via a comment to the question as well.

  • @ajgringo619 Makes sense. But there was nothing like snap:gnome-calculator in install category.
