The default for 'buntu 18.04 is Gimp 2.8. If you also have Gimp 2.10 then most likely that is a flatpak of a snap version. Both of those are 'sandboxed' do not support QT hence gmic_gimp_qt does not work.
Alternatives.
Dump Gimp 2.8 and install a regular Gimp 2.10 from the PPA. see for hints: https://www.gimp-forum.net/Thread-Gimp-2...-18-04-LTS
and a plugin from: https://www.gimp-forum.net/Thread-gmic-g...untu-18-04
Use a portable version, an appimage from https://github.com/aferrero2707/gimp-appimage/releases/
I was never very keen on his appimages but I was trying out the latest Gimp 2.10.13 https://github.com/aferrero2707/gimp-app...4.AppImage (160 MB) and it is not bad. Comes with some plugins gmic_gimp_qt 2.7.2 / resynthesizer. Runs in parallel with what you already have installed.
