After upgrade of system's Python to 3.9; sage no longer starts

[Emmanuel Charpentier]

Setup :

- Debian testing, amd64, 16 GB RAM

- Sage 9.3.beta2 compiled from `develop` git branch, configured to use as much system packages as possible.

A recent system update upgraded system’s python to3.9.rc1. Result :

charpent@zen-book-flip:~$ sage Traceback (most recent call last): File "/usr/local/sage-9/src/bin/sage-ipython", line 9, in <module> from sage.misc.banner import banner ModuleNotFoundError: No module named 'sage'

Suggestions ?

upgrading the python on which sage is built definitely needs a rebuild of all python/cython modules.

The plot thickens : I tried to upgrade to 9.3.beta3. ./configure orked (ith the usual claimfor system packages already installed…), but make fails :

***************************************************************
Error building Sage.

The following package(s) may have failed to build (not necessarily
during this run of 'make all-start'):

* package:         sage_conf-none
  last build time: 7 déc. 10:10
  log file:        /usr/local/sage-9/logs/pkgs/sage_conf-none.log

It is safe to delete any log files and build directories, but they
contain information that is helpful for debugging build problems.
WARNING: If you now run 'make' again, the build directory of the
same version of the package will, by default, be deleted. Set the
environment variable SAGE_KEEP_BUILT_SPKGS=yes to prevent this.

Suggestions ?

make: *** [Makefile:13 : all] Erreur 2

real    0m0,814s
user    0m1,144s
sys    0m0,206s

This also happens after re-running ./bootstrap…

Suggestions ?

Time for make distclean && make, I suppose…

Thanks !
