Hello. After some installation difficulties, I eventually got letsencrpyt installed. I’m using Redhat EHEL6. I know it’s old. I’m getting segmentation faults right away. I don’t know how to troubleshoot this. If I run letsencrypt-auto, I get,
./letsencrypt-auto --verbose
Updating letsencrypt and virtual environment dependencies…
./letsencrypt-auto: line 200: 9208 Segmentation fault (core dumped) $VENV_BIN/pip install -U setuptools
Segmentation faults usually indicate either broken binaries or hardware failures. If you’re using the distribution’s included pip, it’s likely bad hardware.
I found the reason for this Segmentation fault. It is the new gcc compiler version 5.3.1.
With gcc 5.2.1 the cffi package can be compiled and is usable.
You can try it: remove the file _cffi_backend.so and you will see, that all is o.k until
this file will be recreated.
