Hello,
I'm new on Odoo.
I installed Odoo 11.0 Community on a VM under Debion 9.5
I would like to install module Letsencrypt (https://www.odoo.com/apps/modules/11.0/letsencrypt/).
I downloaded ZIP file and uploaded uncompressed files to /usr/lib/python3/dist-packages/odoo/addons on my server.
After restart Odoo server, I cannot see the module in the list to install it.
Thanks in advance for your help.
Every time you add a new module you need to restart odoo and update app list like Niyas said. Hope you installed all the linux packages that are in the instructions. Letsencrypt also won't work if the domain you want to create SSL doesn't point to your server.
