[Software] Gimp language German

[FR-Kuhnen]

Hi,
I've installed gimp and the language-pack-gnome-de. In the "Preferences" - "User Interface" the language is shown as "German[de]" but the language in gimp is just english.
How can I change the language to German?
Thank You in advanced for Your help.
Regards

Try:

sudo apt install language-pack-de language-pack-de-base language-pack-gnome-de

Thank you kapustin. I installed all this things but this changes nothing. :-(

I've now installed the Flatpak-version and there is no problem with the language-settings.
