no I tried to install the packages with the utility UT TWEAK TOOL.
If I do : pkcon --allow-trusted install-local Downloads/my-scope.click
I have Error like that :
Fatal error : ..... Cannot install ... Framework "FRAMEWORK" not present on system (use --force-missing-framework option to override)
Ok but how do I install this framework .. what do I miss?
if someone has an idea ... I thank him in advance!
