Hi,
most probably the problem is due to Conda in your PATH:
PATH: /home/pierretchamitchian/.local/bin/
PATH: /home/pierretchamitchian/miniforge3/bin/
PATH: /home/pierretchamitchian/miniforge3/condabin/
PATH: /usr/local/sbin/
PATH: /usr/local/bin/
PATH: /usr/sbin/
PATH: /usr/bin/
PATH: /sbin/
PATH: /bin/
You might find it faster to install Sage from Conda:
<
https://doc.sagemath.org/html/en/installation/conda.html>
If you still want to build it from source,
please remove the 1st 5 entries from your PATH before trying again (not only Conda, but also /usr/local)
That is, you will need to run in terminal
export PATH=/usr/sbin:/usr/bin:/sbin:/bin
before starting the building process (after a cleanup by "make distclean")
If this fails we need to look at the install.log
(in logs/).
Please post it.
Most likely you'd have hit one of several bugs in 10.6.
