Maybe @uilianries could have a look to this docker issue. Thanks!

[Uilian Ries]

I don't see those errors, it works for me. Could we update Conan version + GCC version? We are running Conan 1.43.1

[James]

Yes, Conan and Gcc version in the image can be upgraded if the training is not broken

@memsharded could you please assign this one to me again. I removed myself by accident and I have no permission to sign.
