building docker image fails

[ZHcubGVlQHNrLmNvbSAK]

I'm trying to build CI/CD using provided Dockerfile, however, building docker image fails printing error message below. my guess is that there is something wrong with tar ball. but I'm not sure what it is.

Looks like segger materials were dropped in this commit: b528046. You can build without it.
