Public bug reported:
Our thumbnailer snap uses ubuntu-app-platform. With the thumbnailer snap
installed and connected, I can remove ubuntu-app-platform without any
problems whatsoever:
$ sudo snap remove ubuntu-app-platform
ubuntu-app-platform removed
$
That doesn't look like a good idea to me because I may not know that
there are other snaps that I have just broken by mistake.
I do find out that I've done something wrong once I try to run our
service:
$ thumbnailer.thumbnailer-service &
[2] 10587
michi@djembefola:~/src/thumbnailer/gstreamer-plugins$ You need to connect the
ubuntu-app-platform package with your application
to reuse shared assets, please run:
snap install ubuntu-app-platform
snap connect thumbnailer:platform ubuntu-app-platform:platform
[2]- Exit 1 thumbnailer.thumbnailer-service
That's a nice error message, and it is very clear. But, unfortunately,
it's too late. I might remove a snap and then not find out for weeks
that I've broken something else...
I think I should get an error when I try to remove a snap that other
snaps depend on. Maybe, if I want to insist on breaking things, a
--force option could be used to let me live dangerously.
But, overall, I think it would be best to have something similar to apt,
which tells me that, if I want to remove X, it'll also remove Y, Z if
they depend on X.
