knoppix was possibly the first linux distro I found 'easy' to use back in the early 2000's. The latest does use Gimp 2.10.8 which is a bit on the old side, but strange that it does not have python 2 as a dependency. Many of the latest debian based distros, ubuntu20, mint20 have dropped python 2 as a default in favour of python 3. Usually you can install python 2 from the distro repository but then it depends on if the gimp-python package is there. For resynthesizer the binary plugins show in the Gimp Filters -> Map section. Not affected by the lack of python
For more mainstream distros, some information here: https://www.gimp-forum.net/Thread-Heal-S...4#pid18354
With a live version of linux running from a DVD adding 'extras' such as the .debs in the above link or maybe a Gimp flatpak version could be a problem. You might get away with a Gimp appimage which is (almost) self contained. Try this one a Gimp 2.10.22

Download, make executable, run. It also contains the resynth/heal plugins already installed. Worth a try.
