Error while installing Rhythmbox Mozilla Plugin

  • 772

I am trying to install Rhythmbox Mozilla PLugin via Synaptic. But I am getting the following error:

rhythmbox-mozilla:
  Depends: rhythmbox (=3.4.2-1ubuntu1~ubuntu18.04) but 3.4.2-4ubuntu1 is to be installed

The command:

apt-cache policy rhythmbox-mozilla

gives the prompt:

rhythmbox-mozilla:
  Installed: (none)
  Candidate: 3.4.2-1ubuntu1~ubuntu18.04
  Version table:
     3.4.2-1ubuntu1~ubuntu18.04 500
        500 http://ppa.launchpad.net/ubuntuhandbook1/apps/ubuntu bionic/main amd64 Packages
rhythmbox mozilla 18.04

  1. We have two problems here:

    1. ppa:ubuntuhandbook1/apps PPA does not respect current version of rhythmbox package from official repository (so it won't install);

    2. Even if we install rhythmbox-mozilla package with some hacks, it will not work with modern Firefox 53+ Quantum (see quote from latest package Changelog):

      rhythmbox 3.4.2-4ubuntu1 source package in Ubuntu
      Changelog

      rhythmbox (3.4.2-4ubuntu1) bionic; urgency=medium
      ...
      * Stop building rhythmbox-plugin-mozilla since it won't work in Firefox 53+

    But if you need to play video in your browser, then you can install Mozilla SeaMonkey all-in-one internet application suite and use it with VLC-plugin:

    cat <<EOF | sudo tee /etc/apt/sources.list.d/mozilla.list
deb http://downloads.sourceforge.net/project/ubuntuzilla/mozilla/apt all main
EOF

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 2667CA5C
sudo apt-get update
sudo apt-get install browser-plugin-vlc seamonkey-mozilla-build

    I view RTSP streams this way on Ubuntu 16.04 LTS.
