• Operating System / Platform: Ubuntu 20.04.2 LTS
• mandelbulber2 => continuous (v2.26-dev)
• Compiler => :grey_question:

Detailed description

I tried building a container from the provided Dockerfile but ran into issues in the final stage.

1. COPY Fails

• Copying the tar file from a previous builder stage fails.

It appears at some point the archive changed from being .tar.xz to .tar.zst.

2. Problems with User

When passing user $(id) as the USER_UID it's still not enough to run mandelbulber.

Steps to reproduce

1. COPY Fails

$ git clone git@github.com:buddhi1980/mandelbulber2.git
...
$ cd mandelbulber2/
$ git checkout b7685c2
...
$ docker build -t buddhi1980/mandelbulber2 .

2. Problems with User
