Running on Linux - FIREXDF/SSBUFightPlanner GitHub Wiki
I try one time to compile FightPlanner for Linux on Ubuntu it was really buggy
So you can try to use the tutorial of HedgeModManager by just replace the HMM executable by FightPlanner, Link of the tutorial : https://github.com/thesupersonic16/HedgeModManager/wiki/Running-on-Linux-(Bottles)#introduction
I can't help with that i got a Windows machine and i don't know if this will work or not.
