I will use bash, no worries I am not religiously bound to csh and
friends.

Ok, makes sense

That is what confused me

Aeh, I forgot to delete  these lines, sorry ignore them, in fact I was
not in the correct directory.

Good, at least something useful will come out from my intents. ;-)


When you say kallithea user, do you mean me, or do you mean that I shall
create a user (and group) named kallithea?

Well I tried to do this, but it failed again.

Here is what I did, using bash

 sudo mkdir /srv/kallithea
 sudo chown -R oub /srv/kallithea
 sudo chgrp -R oub /srv/kallithea
 cd $HOME/src/kallithea
python3 -m venv /srv/kallithea/venv
. /srv/kallithea/venv/bin/activate
pip install --upgrade pip setuptools
pip install --upgrade kallithea
