@dobey Ah ok! thanks for the tips!

@dobey i tried adding thr line to the .desktop file but it still closes on launch.

you mentioned something about a log file, i am sorry if this is a bit of a newbie question but where could i find the log file?

Hi,

You can use this app as a convenience : https://open-store.io/app/logviewer.neothethird
And you can have a look in .cache/upstart/

After adding the line to the desktop file i seem to still not be able to run the app.

i checked the .desktop file in /home/phablet/.local/share/applications

and tried running the line behind Exec=
Manually in the terminal like so:
aa-exec-click -p javatest.comlarsic_JavaTest_1.5.0 -- JavaBin/bin/java -jar main.jar
and i get the error aa-exec: ERROR: profile 'javatest.comlarsic_JavaTest_1.5.0' does not exist

Here is the .desktop file that shows in the applications folder:

[Desktop Entry]
Name=Java-test
Exec=aa-exec-click -p javatest.comlarsic_JavaTest_1.5.0 -- JavaBin/bin/java -jar main.jar
Icon=/opt/click.ubuntu.com/.click/users/phablet/javatest.comlarsic/assets/logo.svg
Terminal=false
Type=Application
X-Ubuntu-Touch=true
X-Ubuntu-XMir-Enable=true
Path=/opt/click.ubuntu.com/.click/users/phablet/javatest.comlarsic
X-Ubuntu-Old-Icon=assets/logo.svg
X-Ubuntu-Application-ID=javatest.comlarsic_JavaTest_1.5.0
X-Ubuntu-UAL-Source-Desktop=/opt/click.ubuntu.com/.click/users/phablet/javatest.comlarsic/JavaTest.desktop

what seems to be going wrong here?

@ComLarsic Try uninstalling the app, and then installing it again. Or change the version number and building a new click, and installing that.

You did edit the original .desktop file and build a new click, rather than editing the .desktop in ~/.local/share/applications/ right?

ComLarsic

@dobey no, i did not edit the .desktop in the applicion folder manually. i have tried reinstalling it and i still get the same error. i will try to rebuild it and completly remove the app using UTTweak tool

I just had a bit of a play with this and was able to get it working with just the following changes to the original repository:

Set X-Ubuntu-XMir-Enable=true in the .desktop file
Remove the policy groups from the AppArmor profile and set "template": "unconfined", instead

It seems x-mir-helper isn't able to launch confined, perhaps there should be a discussion about adding an AppArmor policy for these use cases?

If that's true, probably a good idea to open an issue about it at https://github.com/ubports/apparmor-easyprof-ubuntu

@dobey Okay, will do!
