I installed Umbrello on F28 from repository, version is 2.25.3.

Program works but I would like to use it with english language, despite my OS language is finnish. UML terminology does not translate very well.

Umbrello seems to have a language choice under help-menu but is does not do anything. It allows to choose a long list of languages, says at the ok button that program needs to be restarted to take the change in effect. But after restart the UI language is still finnish. The language dialog however claims that the language is what I chose. I tried multiple languages US English, british english etc.

Any idea should this even work on Fedora, do I have to change the OS language instead? Or is it Umbrello bug or Fedora packaging issue?

I can see the change in .config/klanguageoverridesrc as
Code:
[Language]
umbrello5=@ByteArray(en_US)
