I receive this same error running on Debian (with no gnome or kde desktop, only openbox).

I also am having the same problem. My Linux is up to date. I was following this to install PyCharm community on Chromebook Linux. after installing menulibre, the first time executing I get this issue. https://www.linuxmadesimple.info/2020/11/how-to-install-pycharm-on-chromebook.html

In both crostini and wsl2 menulibre does not work because it needs an active linux desktop-environment.

In wsl2 I can start Xephyr and then run xfce4 in its own window In that widnow I can then start menulibre and add *.sh, *.jar and extracted tarballs as programs which can then run/be started from windows.

But in crostini I cannot get that to work.
