ubuntu-ui-toolkit-examples has unsatisfiable qtdeclarative5-ubuntu-ui-toolkit-plugin dependency (conflicts with -gles)

[Nicholas Skaggs]

Running adt for click testing fails when using the x86 emulator. Both r/o and r/w mode fail in the same way. During the installation of depends, dpkg configure fails and the test is aborted.

Status changed to 'Confirmed' because the bug affects multiple users.

ubuntu-ui-toolkit-examples is uninstallable in that environment indeed: It depends on qtdeclarative5-ubuntu-ui-toolkit-plugin (= 0.1.49+14.10.20140715-0ubuntu1), i. e. a versioned dependency. This won't be satisfied by the "Provides: qtdeclarative5-ubuntu-ui-toolkit-plugin" of qtdeclarative5-ubuntu-ui-toolkit-plugin-gles, but this is installed by default.

So ubuntu-ui-toolkit-examples either needs to drop the strict versioned dependency (so that the Provides: gets effective), or grow an alternative dependency to qtdeclarative5-ubuntu-ui-toolkit-plugin-gles.

I created a MP for this.
