SOLVED !
PlayOnLinux needed to be updated to latest version 4.3, then you can download WineStaging3.15 inside PlayOnLinux, and then AmiKitXE for Linux will work!
PLEASE FOLLOW THIS STEP BY STEP LINUX GUIDE FOR AMIKIT XE (by Epsilon's Amiga Blog) this is the ONLY way to make AmiKitXE for Linux work right now!!!
http://amigax1000.blogspot.com/2019/06/amikit-xe-on-windows-macos-and-linux.html(Scroll down to the Linux part of the install where it says "Last, but not least, I wanted to try out the Linux version of AmiKit XE." - and follow exactly the step by step guide!)
*AMIKIT DEVELOPER(S) PLEASE UPDATE THE OFFICIAL AMIKIT GUIDE.PDF TO INCLUDE THE HELP/STEP BY STEP FROM Epsilons Amiga Blog FOR THE PLAYONLINUX INSTALL GUIDE *
- AmiKitXE runs fantastic on Linux once you get past the install
Thanks
