Can't launch snaps

[Robert Ancell]

[Impact]
No method of launching snaps from GNOME Software.

[Test Case]
1. Open GNOME Software
2. Search for a snap (e.g. "moon-buggy")
3. Click on snap description
4. Click install

Expected result:
Snap is installed and launch button is shown (as for .deb apps)

Observed result:
Snap is installed; no launch button shown.

[Regression potential]
Low. We now take advantage of new snapd API to make snaps launchable.

Hello Robert, or anyone else affected,

Accepted snapd into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/snapd/2.0.9 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Fwiw, the snapd part of this bug (that is now in fix-commited state) is just a prerequisite for gnome-software to implement this feature. So just to be clear. The snapd change does not add the button but with the snapd change now gnome-software has all the information to add the button.

[Robert Ancell (robert-ancell)]

I've opened bug 1595023 for the next step - determining which apps a graphical and which are terminal.

[Michael Vogt (mvo)]

Setting to verification-done (for snapd) based on the feedback from Robert that he can use it in gnome-software now.
