Hello, I was hit by this bug, trying to automate my config with Ansible.
Even setting tt-rss/self_url_path after package install, and running "dpkg-reconfigure -f noninteractive tt-rss" will fail, because it will read the old value from the existing config file, and overwrite the debconf value.
I will have to directly patch the config file, which I tried to avoid. Thanks, Nicolas
