Debian Sid has updated its Python version to 3.13. In trying to build sage 10.5 from source, I get:
[sagelib-10.5] [spkg-install] error: command '/usr/bin/g++' failed with exit code 1

[sagelib-10.5] Instead, the following commands setup all environment variables
[sagelib-10.5] correctly and load a subshell for you to debug the error:
[sagelib-10.5] (cd '/home/finotti/src/sage-10.5/local/var/lib/sage/venv-python3.12.5/var/tmp/sage/build/sagelib-10.5' && '/home/finotti/src/sage-10.5/sage' --buildsh)
[sagelib-10.5] When you are done debugging, you can type "exit" to leave the subshell.
