Dear Easybuilders,

I am having troubles trying to install EB 5.2.0
I have installed python3.6 , and I installed EB 5.2.0 from version 5.1.1.
But after installation eb 5.2.0 complains about the python version.

So I have installed python3.11 and "activate" pip with "python3.11 -m
ensurepip --upgrade"
to be able to locate the pip version.

Then, I have followed the instructions in :
https://docs.easybuild.io/installation/#eb_as_module
After passing Step 1 successfully, I've got stacked in Step 2, trying to
install it as a module :

*Step1: *
[easybuild@na10:~/eb/git/easybuild-easyconfigs]$* export
EB_TMPDIR=/tmp/easybuild/en_tmp*
[easybuild@na10:~/eb/git/easybuild-easyconfigs]$ *python3.11 -m pip install
--ignore-installed --prefix $EB_TMPDIR easybuild*
...
Successfully installed easybuild-5.2.0 easybuild-easyblocks-5.2.0
easybuild-easyconfigs-5.2.0 easybuild-framework-5.2.0

Step2;
[easybuild@na10:~/eb/git/easybuild-easyconfigs]$ *export
PATH=$EB_TMPDIR/bin:$PATH*
[easybuild@na10:~/eb/git/easybuild-easyconfigs]$ *export
PYTHONPATH=$(/bin/ls -rtd -1 $EB_TMPDIR/lib*/python*/site-packages | tail
-1):$PYTHONPATH*
[easybuild@na10:~/eb/git/easybuild-easyconfigs]$ *export
EB_PYTHON=python3.11*
[easybuild@na10:~/eb/git/easybuild-easyconfigs]$ *eb
--install-latest-eb-release
--installpath="/software-nas/eb2024/easybuild/software/common/"*
...

Any hint on how to proceed ?

Thank you in advance !
