Cannot launch hp tools

[Jean-Baptiste Lallement]

hplip is a common set of tools to manage HP printers. The tools fail to start on unity8 and the indicator is not displayed in the top panel.

The following message is displayed on the command line:
---------
HP Linux Imaging and Printing System (ver. 3.16.11)
Printer/Fax Setup Utility ver. 9.0

[Michał Sawicz (saviq)]

This means the snap does not include the mir QPA and/or doesn't connect to mir-libs?

Not a unity8 bug.

As a separate thing, no support for application indicators was planned in unity8.

[Michał Sawicz (saviq)]

Sorry, wrong bug I commented on, however, we'll need the output from unity8.log to try and see why the app was rejected.

[Michał Sawicz (saviq)]

Are you launching it from the terminal? That's not supported, you need to run it from the app drawer or via ubuntu-app-launch.

Find the app id with:
$ ubuntu-app-launch-appids

And launch:
$ ubuntu-app-launch <app_id>

[Jean-Baptiste Lallement (jibel)]

It does not work from the app drawer either, that's the 1rst thing I tried. I'll attach more logs.

[Albert Astals Cid (aacid)]

It "starts" from the app drawer here, but you get an empty translucent window
