First of all, thank you for sharing the Dockerfile. I edited your post so the code is formatted properly. Please, use </> button when you write your message to highlight codes. If you don’t do that, the markdown filter can totally ruin your code so we don’t understand it.
Seeing your code I realized where your current “adventure” started so I leave it here for others before they ask why you copy binaries from the host, although I wouldn’t do that either and it can cause issues if you don’t do it right.
So if I understand well, you solved everything. That’s great
