ubuntu-app-launch dolphin fails [Could not start process Cannot talk to klauncher: The name org.kde.klauncher was not provided by any .service files.]

[fcole90]

Try installing dolphin (native, no libertine) and then launch it. The following message appears:

Could not start process Cannot talk to klauncher: The name org.kde.klauncher was not provided by any .service files.

[Stephen M. Webb (bregma)]

Are you trying to run a KDE component in a Libertine container or are you trying to run an X11 application outside of a Libertine container?

[fcole90 (fcole90)]

I'm running it outside of Libertine, with the command

ubuntu-app-launch dolphin

[Launchpad Janitor (janitor)]

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

[Ted Gould (ted)]

Sounds like dolphin requires an additional package or interface to be useful. Not an application setup issue.

klauncher5 lives in /usr/lib/x86_64-linux-gnu/libexec/kf5/klauncher and gets started automatically by kdeinit5. However, kdeinit5 seems to open an X11 display so that's probably why it doesn't work under u8.

[Lukáš Tinkl (lukas-kde)]

It might very well be that qtmir's ApplicationManager::authorizeSession is not letting kdeinit5/klauncher5 through... investigating

Solution to this is comment #8 plus we need to fix kinit: https://cgit.kde.org/kinit.git/tree/src/kdeinit/kinit.cpp#n1364

It aborts when it sees no DISPLAY envvar; which doesn't make sense, it can very well continue without.
