Issue

After installing sage per the exact instructions on this page: https://doc.sagemath.org/html/en/installation/conda.html#sec-installation-conda Running sage leads to an immediate crash Python version is 3.9

Stack backtrace

Could not attach to process. If your uid matches the uid of the target process, check the setting of /proc/sys/kernel/yama/ptrace_scope, or try again as the root user. For more details, see /etc/sysctl.d/10-ptrace.conf ptrace: Inappropriate ioctl for device. No stack. Traceback (most recent call last): File "", line 25, in ModuleNotFoundError: No module named 'Cython' Error while executing Python code. warning: Inferior ID 1 is not running. Saved trace to /home/cenobyte/.sage/crash_logs/crash_l8jzlsxk.log

Unhandled SIGILL: An illegal instruction occurred. This probably occurred because a compiled module has a bug in it and is not properly wrapped with sig_on(), sig_off(). Python will now terminate.
