Force upgrade to any lower version to version less than or equal to 19.8.*. config.php is the only configuration file for tt-rss app the FreedomBox modifies. Comparison of config.php from 19.8 shows that there are no major changes since 18.12. Changes to the configuration file are likely to be minor and from Debian packaging. Force upgrading to all versions until 19.8.* should be okay by retaining new configuration and performing FreedomBox changes on top everything new configuration file is installed. Tests: - Install tt-rss version 18.12-1 using a test repository and custom priority. Then remove the custom priority and trigger 'apt update'. This will trigger an force upgrade of tt-rss to version 18.12-1.1. Verify that the tt-rss interface is available and functional. - Install tt-rss version 18.12-1.1 freshly. Verify that the tt-rss interface is available and functional. Signed-off-by: Sunil Mohan Adapa <sunil@medhas.org> Reviewed-by: James Valleroy <jvalleroy@mailbox.org>
