Ofnuts might have some good advice.
However, I doubt if it will be as easy as that. For I example I run a (sort of) portable Gimp 2.8 in my kubuntu 18.04 which has Gimp 2.10.14 installed. Lots and lots of tracking down compatible library files to get it working.
Just out of interest, which is the 'new' version of linux are you using?
