Warnings/Errors after upgrading 2.18-> 2.3.2

Ciao,
after upgrading from 2.1.8 to 2.3.2 I get some warnings/errors (see below), the Indico itself seems to be working ok as far as I can tell.
Any advice?
Thank you,
Michelangelo

For the ASSETS_DIR warning you can just remove that obsolete entry from your indico.conf.

Not sure where urllib3 1.22 is coming from… that’s a pretty old version. Maybe time to update some more stuff… pip install -U pip setuptools and pip install 'urllib3==1.25.11'.

How can I find the indico.conf in use? I inherited an old install and I find a number of [.]indico.conf

that did the trick, thank you !

/opt/indico/etc/indico.conf

Thank you, will check.

BTW, this is mentioned in the upgrade docs: https://docs.getindico.io/en/latest/installation/upgrade/#upgrading-from-2-x-to-2-2

Exactly, I am aware of that.
The sed oneliner deletes the ASSETS_DIR string from the configuration file in ~/etc/, where ~ is /opt/indico
I ran the oneliner when upgrading - point is the configuration file does not contain the ASSETS_DIR directive :slight_smile:
This is the nearest match:

AssetsDir = '/opt/indico/assets'

Indico.conf location is explained here , so I am wondering if the configuration file is overridden at some point.
Thanks!

Oh I see, looks like the config file is even older - we changed from camelcase to uppercase names (but normalize to uppercase) at some point between 1.9 and 2.0. I would recommend updating all the keys to the new values, because now that you reminded me of the normalization logic that’s something we’ll remove in 3.0.
