Launching apps with Terminal=true does not work / refers to xterm

[Alex]

Trying to launch an app via the app launcher that is supposed to launch in a terminal window (Terminal=true in the corresponding .desktop file) does not work (e.g. htop, vim). An entry in journalctl alerts

sh: 1: exec: xterm: not found

which is not installed (by default).

Please run apport-collect 1873428 so that the details of your system is attached to this report.

So that we can assess which package is correct please describe what your app launcher looks like (screenshot)

The problem occurs in both the default AppMenu Widget and the Alt+F2 app launcher (which I assume both access the same launcher entries). Do you really want me to provide a screenshot of those or is it clear what I am referring to?

I have also checked the my x-terminal-emulator alternative, it seems correct and I can also open a terminal with Ctrl+Alt+t without any problems.

x-terminal-emulator -> /usr/bin/tilix.wrapper

Ok - you are referring to 20.04. The default appmenu is the grid/list view menu - not the classic budgie desktop menu.

The Alt+F2 pop-up is from budgie-desktop.

Your issue is this: https://github.com/elementary/applications-menu/issues/53#issuecomment-524092049

Its a GLIB issue - with no real resolution. Adding xterm is a workaround, but its not something we will be doing out of the box since having multiple terminal's in the menu is confusing.

We could in theory hard-code something for UB's tilix terminal for the menu but that will break other distros.

I'll add the issue to the 20.04 release notes but there isn't anything we can readily do here.

[Ubuntu budgie (ubuntu-budgie)]

Note - from the linked issue GLIB code there is a list of terminals that are supported.

You could do a wacky "workaround" to fool GLIB to assume one of them is installed

e.g.

    sudo ln -s /usr/bin/tilix /usr/bin/nxterm

Reassign to budgie-extras - maybe we can add the above workaround in the budgie-network-applet package postinst/prerm
