I know your pain Artisto. I just went through the same thing last week. In the end I gave up and turned to AI. I used Claude ai. I asked some questions about why I could not get winboat to work. It turned out that I did ot have everything loaded.
So this is how I got things to work. In the Winboat install page it will show a list of things that must be installed besides Docker. Such as Docker container etc. Each one will have a line and need a green check mark on the left to show winboat has got it. I started by asking AI how to install the first one with the terminal.Once in I went to the next line, etc. There are4 or 5 lines that need to be run in terminal. That was it. Runs great now but did have a bump or two before settling down. That said, I could not have done it without AI.
