| Issue | Solution | |-------|----------| | pip not found for new Python | Run python3.12 -m ensurepip | | SSL module missing | Install libssl-dev / openssl-devel and recompile | | make fails with _ctypes | Install libffi-dev and recompile | | altinstall still overwrites python3 ? | Manually check /usr/bin/python3 – should still point to system version | upgrade python linux
