Expected Behavior
No CPP build failures

[jhurliman]

Was this a transient error? C++ build succeeded for me in several CI runs a few minutes ago.

[achim-k]

It could be. Will confirm and close this issue if it can't be reproduced

Edit: Working now again

[adityasivarajmz]

I am getting the same error code while building CPP examples.

How do I solve this?

[adityasivarajmz]

I found the problem. Conan was updated to version 2.0.0 few days ago. It doesn't have the init command under conan config. FIX: Change line 25 in dev.Dockerfile to RUN pip --no-cache-dir install conan==1.59.0

[achim-k]

Indeed, we are currently in the process of migrating to conan 2.x. See #375
