git.osgeo.org/gitea giving warning when pushing -upgrade pip and setuptools

[robe]

As noted on postgis

​https://trac.osgeo.org/postgis/ticket/4580

When pushing to gitea, it is now showing a warning:

It's still unclear to me why gitea's git is affected by python. I tried setting that setting in apache/etc/envvars as suggested by note and restarting apache on tracsvn-dev instance on osgeo4 which has the same issue. That did now help.

However upgrading setup tools did seem to do the trick

pip install -U setuptools

I need to confirm that's all that is needed though as I was fussing with configs.

okay I forgot that in dev I had upgraded that to trac 1.2.5, which required me to upgrade pip as well. So the new setup tools couldn't be upgraded without first upgrading pip.

So steps were:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
python get-pip.py
pip install -U setuptools

which yielded the following:
