Looking for an RSS reader

Can anyone recommend an #RSS reader that can be synced using NextCloud’s file sync? (I know there is NextCloud News but this doesn’t work on my NextCloud which i get from disroot)

I’d like some application where i can save the state to files located in my NextCloud files directory. (I could export and then import but i don't want to have to do this when i start or exit my RSS reader, instead i'd like the process to happen automatically)

Wishlist:
* Works on Ubuntu
* Free software

Grateful for help with this!
