movim binary package in Ubuntu Focal amd64

 Movim is a decentralised social network, written in PHP and HTML5 and
 based on the XMPP standard protocol.
 .
 Movim is a web-based Jabber (XMPP) client, which also exposes a social
 network functionality using standards-conformant PubSub functionality.
 It supports microblogging (both “private” posts, i.e. shown only to
 one’s Jabber contacts, and “public” ones, which are indeed publicly
 available, including an RSS feed and a web interface showing all public
 blog posts of a user), communities, etc.
 .
 Movim is a client, that means it still requires a Jabber/XMPP server
 to function. https://github.com/movim/movim/wiki#xmpp-servers contains
 upstream documentation on how to best configure your server to work well
 with Movim. A Movim installation (“pod”) can allow users of one or
 multiple Jabber servers to log into that pod; users of other Jabber
 servers will need to install their own Movim instance.
