After the recent upgrade, my FreedomBox (testing) had Shaarli and TT-RSS disabled. I was able to toggle Shaarli on from the UI, but not TT-RSS. Its systemd unit is “masked”.
Warning: The unit file, source configuration file or drop-ins of tt-rss.service changed on disk. Run 'systemctl daemon-reload' to reload units. ○ tt-rss.service Loaded: masked (Reason: Unit tt-rss.service is masked.) Drop-In: /usr/lib/systemd/system/tt-rss.service.d └─freedombox.conf Active: inactive (dead)
Update: Shaarli appears to be enabled, but accessing the app returns a 404 response (same as TT-RSS).
