I am new to odoo so forgive the question. I am trying to install this add-on and having some issues https://apps.odoo.com/apps/modules/12.0/accounting_pdf_reports/

I have done a good bit of searing on this and found instructions on copying the third party app to the /otp/odoo12/odoo-custom-addons directory then changing the owner and file permissions of the directory using the following

sudo shown -R odoo12:odoo12 odoo-custom-addons

sudo chmod -R 775 odoo-custom-addons

I then restarted my server and entered developer mode and navigated to Apps and selected Update Apps List however no new app showed up and the new reports are not avalible. I am sure I am missing something small but I can't find anything else in any of the posts. Thanks in advance for any help.

EDIT: For anyone else that finds this post here is what I have learned.

For logging to work you have to set up the file to log to and enable logging.

bash#mkdir -p /var/log/openerp/
bash#touch /var/log/openerp/openerp-server.log
bash#chown odoo12 /var/log/openerp/openerp-server.log
bash#chmod 644 /var/log/openerp/openerp-server.log

also third party apps when placed in either app folder or at least this app doesn't register as an app so when you go to the apps section you have to remove the filter to see it and install it.
