Can't install snap after removing it

Question

I'm pretty new to snaps, so I didn't know if it was a bug or if I was missing something.

I installed a Snap via "sudo snap install ubuntu-clock-app" then I removed it via "sudo snap remove ubuntu-clock-app", because the app didn't want to start, now I tried to install it again to file a bug, but it says that it is already installed (it isn't)

error: can't install "ubuntu-clock-app": snap "ubuntu-clock-app" already installed

Answer 1

Sorry you're having problems with this. Fortunately we released snapd 2.0.3 to xenial last week, so we should be able to get you back on track.

First, please update and make sure you're on 2.0.3; dpkg -l snapd should show you that version.

Next, let's clean up your snapd state, which has gotten into a mess. This deletes all snaps from your system and gets you back to an empty state: zyga's reset-state script.

This fixes all known bugs, so let us know if you manage to break it again!

Answer 2

This smells rather like a bug to me. Do you mind opening it against the snapd package? https://bugs.launchpad.net/ubuntu/+source/snapd

Answer 3

I'm one of the snappy developers. I'm sorry you are bumping into errors. I'll try to help you out.

Can you pastebin two more things for me please?

$ mount | pastebinit

And then:

$ snap list | pastebinit

Thanks

You might want to use the

snap changes

command to see what went on. Then you can look at the details of the particular change set you're interested in (ubuntu-clock-app) with snap changes $CHANGEID to find out more.

You can also learn more about snappy changes.

I believe you can also reset the state machine, but as it's a manual step and I'm not an expert on doing it, I'll leave it for the snappy developers to comment on :)
