What SHA1 of https://github.com/kalray/build-scripts are you using?

We are building our toolchain on Ubuntu 18.04 / 20.04 and 22.04 without
issues, I don't understand why it does not work for you, although indeed
the error log you are having pops out on my search engine and seems to
be some well known issue.

If the build-script does not work for you, you can still use the
pre-built toolchains generated by the GitHub automated actions:
https://github.com/kalray/build-scripts/releases/tag/v4.11.1 ("latest"
means 22.04)

I hope it will work for you.

Regards,
