Help for iMac G4 PPC Ubuntu Mate


I need help installing ubuntu mate on my computer iMac G4 PowerPC, I have installed os x 10.15 but I’m tired because it does not work to perfection and I get to use Linux and preferred Ubuntu Mate but it has given me problems in the installation because I downloaded the Version for ppc and all good I think because it is loading with the ubuntu mate logo but then either it throws error or it stays stuck.

I get Ubuntu mate 16.04.1
