I was able to hit this issue when U8 crashed while ubuntu-app-test was open. Leaving behind in: /run/user/1000/systemd/transient/ubuntu-app-launch-application-legacy-ubuntu-app-test-.service
Once this was stuck there even relogging seems to be causing this issue. If you remove that file then it works again. To reproduce this issue: 1) In U8 on a terminal start ubuntu-app-test with any application 2) Copy the /run/user/1000/systemd/transient/ubuntu-app-launch-application-legacy-ubuntu-app-test-.service somewhere 3) Relog into U8 4) Copy the *.service file back into /run/user/1000/systemd/transient/ 5) Try to use ubuntu-app-test again from a terminal in U8 Then you'll hit this error. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1662400 Title: ubuntu-app-test fails to launch apps at all [CRITICAL **: Unable to get PID for 'ubuntu-app-test' application] To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1662400/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
