I’ve installed Tryton 5.0 with the Debian package in buster, and manually installed the web interface. I then installed the accounts module with:
apt install tryton-modules-account sudo -u tryton trytond-admin -c /etc/tryton/trytond.conf -d tryton --update-modules-list
The modules appear in the admin, and I marked it for activation. After clicking ‘Perform pending activations’, I get a message saying that the modules activated successfully and a tab opens up saying that module configuration is complete.
Then the page reloads, and nothing has changed. The modules are still marked for activation, and I can repeat the process of activating them as many times as I like, with no results. I see no errors in any of the logs, no indication that anything is failing.
