Concrete ML Example fails: illegal instruction (Debian Bookworm) #1093
Description
Summary
I wanted to reproduce some experiments (that worked previously on a VM) on a freshly installed dedicated server. However, I run into an error when compiling the model. To check whether the problem was coming from my code or from ConcreteML, I run the basic logistic regression example from the documentation (https://docs.zama.ai/concrete-ml/built-in-models/linear#example), and I run into the same issue:

Illegal instruction
I checked related GitHub issues #485 and #699 , but the discussions there did not help.
For example, I have checked the flags on my CPU, and I have the AES flag:
