I have newly install edubuntu 14.04 LTS OS in my hp laptop. Now installing all the required software. But while playing mp3 files, it is informed that some plug in will be installed. But while try to install the same errors may occurs . I tried several times , but problem is same.
No mp3 file play with Rhythmbox. How is it minimized?
Open a shell terminal window and run this supercommand:
sudo apt-get update && sudo apt-get check && sudo apt-get install ubuntu-restricted-extras ubuntu-restricted-addons librhythmbox-core8 libmad0 libmpg123-0 --reinstall -y && sudo apt-get autoremove -y
...then restart your computer and try again. If Rhythmbox still can't play MP3, install Audacious and VLC Media Player:
sudo apt-get install audacious vlc
...then try playing MP3 with VLC or Audacious. They're both excelent media players: Audacious plays audio tracks, VLC plays audio, video and even images.
