GIMP language DE??

[gNeandr]

Installed GIMP 2.10 from https://www.gimp.org/downloads/index-comments.html but also from https://www.gimp24.de/gimp_download_linux.php in the hope to get the locale UI version for DE. And also using https://wiki.ubuntuusers.de/GIMP/ only gives the EN version.

Maybe it's because my operating system is

Code:

System:
  Kernel: 5.4.0-54-generic x86_64 bits: 64 Desktop: Xfce 4.14.2
  Distro: Linux Mint 20 Ulyana

 with the language setting for EN.

However, I assume there is a method to get a GIMP DE version to work, just how ?  (Without changing the base OS EN version!).
Any help is greatly appreciated, thanks
