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?
sudo apt-get install package
. Remove package with that plugins name. If you need to install more than one package, runsudo apt-get install package1 package 2
etc. Make sure you're connected to the internet.
