Hi,

i tried to upgrade from 2.0rc1 to 2.0rc2

systemctl stop indico-celery.service
su - indico
source ~/.venv/bin/activate
pip install -U --pre indico

I got this error message

Traceback (most recent call last):

This sounds like some (strange) problem with your virtualenv.

Is pip itself working (see if other commands like pip freeze work or fail as well)? If it does work, try try upgrading pip and setuptools first using pip install -U setuptools pip

Yes, you’re right, pip is not working.

I did

su - indico
pip install -U setuptools pip
-su: pip : commande introuvable

I does not work neiher…
I also did

indico:~$ virtualenv ~/.venv

Is there something wrong here ? Root and indico user confused on pip ?

Is this right to have python and python2 here ?

Yes, these symlinks are normal. The easiest option to hopefully fix whatever is wrong with your virtualenv is to recreate it, by running these commands as the indico user:

deactivate  # just in case your old virtualenv is still active
rm -rf ~/.venv
virtualenv ~/.venv
source ~/.venv/bin/activate
pip install -U pip setuptools
pip install --pre indico

Thank you so much, it worked !
I’m totally new to pyhton virtualenv, i was lost.
Indico is upgraded now
