Dear all, To summarise what I found qua Mike's installation issues:
It seems that macOS/XCode stopped providing Pythons what are good enough to use to install Sage from source, as their networking is broken in some way which make it impossible to fetch packages for installation. The main symptome looks like an SSL cert check failure while fetching pip spkg tarball by sage_bootstrap/download/transfer.py: [pip-24.2] Attempting to download package pip-24.2-py3-none-any.whl from mirrors [pip-24.2] https://github.com/sagemath/sage/releases/download/10.6/pip-24.2-py3-none-any.whl [pip-24.2] [xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx] [pip-24.2] ERROR [transfer|run:135]: [Errno socket error] [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:992) [....] [pip-24.2] File "/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/ssl.py", line 1346, in do_handshake [pip-24.2] self._sslobj.do_handshake() [pip-24.2] ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:992) [pip-24.2] [pip-24.2] The above exception was the direct cause of the following exception: [pip-24.2] [pip-24.2] Traceback (most recent call last): [pip-24.2] File "/Users/mike/sage/build/bin/../sage_bootstrap/tarball.py", line 185, in download [pip-24.2] Download(url, destination).run() [pip-24.2] File "/Users/mike/sage/build/bin/../sage_bootstrap/download/transfer.py", line 137, in run [pip-24.2] raise error [pip-24.2] File "/Users/mike/sage/build/bin/../sage_bootstrap/download/transfer.py", line 128, in run [pip-24.2] filename, info = opener.retrieve( [pip-24.2] ^^^^^^^^^^^^^^^^ [pip-24.2] File "/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/urllib/request.py", line 1821, in retrieve [pip-24.2] fp = self.open(url, data) [pip-24.2] ^^^^^^^^^^^^^^^^^^^^ [pip-24.2] File "/Library/Frameworks/Python.framework/Versions/3.11/lib/python3.11/urllib/request.py", line 1793, in open [pip-24.2] raise OSError('socket error', msg) from msg [pip-24.2] OSError: [Errno socket error] [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:992) These capabilities are not tested by ./configure The Python I'm talking about is not to be confused with tests to use "system" Python to run sagelib, these tests are more detailed, in particular availability of Python modules sqlite3, ctypes, math, hashlib, socket, zlib, ssl, ensurepip is checked. I don't know whether a modern (Troyan horse) Python from Apple lacks some of these modules, or perhaps some of these modules are broken. ---------------------------------------------------------------------------------- To me, the right course of action is to purge from Sage its (half-broken anyway) capabilities to build Python (as on macOS there is an abundance of Pythons either from python.org or from Homebrew, and building Python is tricky do to due to SSL issues); then all this mess would not have arisen in the 1st place. And, sorry for sounding like a broken record: building and providing Python should be left to experts, are we are not experts in this.
