I cloned the repo, changed USER_ID =1000 to USER_ID1=1001 and GROUP_ID =1000 to GROUP_ID1 =1001 , and then recompiled it. The error dispeared, but with another question.

Meanwhile, I can work with Dockerfile.unix without known issues.
I don't have much knowledge of Rust, and I'm not skilled at debugging it with LLDB right now.

Is your user part of the docker group on debian?

[rafaelfranca]

Can you also test with the new version?
