Edit2: Never mind. Please ignore this. I thought it would be fun to get this working on Linux, but after trying this for a couple of hours I'm kind of over the novelty. I'm blowing away the system I'm using for this and just doing it under Windows instead. I figure that will be much easier. You can delete or ignore this post. Thank you.
Edit: Okay, I found the advice of someone else about pointing to the ISO as an archive, unchecking the four boxes and that got me past the error I had below. However, right after it says IMPORTING OPERATING SYSTEM FILES... SIT TIGHT it says INTERNAL ERROR.. please check Support Forum.
Progress is being made, but I'm not sure what I should do now.
I wanted to try the free X version first to see what I thought before buying. However, it immediately fails when I first try and run it. I am on the latest POP_OS and running PlayOnLinux. I complete the install by following the instructions on your site. However, when I first try and run it I get an error immediately. «Alias: argument line invalid or too long» This is showing up in the AROS window, so the error message looks like an error message would on an Amiga (i.e. not a Linux error).
I have the Amiga Forever ISO (ver 9). I was expecting it to ask for the ISO image to do the install. However, it fails with the above error message within a second or two of launching it. I tried going into «Configure» and down to WinUAE Properties/hardware/CD & Hard drives and select the ISO and it still gives the same error. I add a CD drive and mount the ISO and it still fails. I made a new ISO of Amiga Forever and it fails. I'm kind of frustrated. I see in images online that Amikit X normally says Welcome to AmiKit and you just select the button for Amiga Forever. It doesn't do that for me. For grins I installed Crossover and it installs Amiga Forever just fine. So, I'm obviously missing something, but I can't figure it out. Any ideas?
