Getting an Error Message In Updating Softwares

Hi,

I have recently purchased a new Lenovo Thinkpad E420 and installed Ubuntu.

I got the installer from, the look and functionality really appeal to me. 

I then installed all the necessary software needed to make it work, for example gimp, kile, adobe flash player, audacious, LinuxDc++, vlc, chrome, acrobat reader etc.

When I finished this and tried to update through the update button I get the following message:

Requires installation on untrusted packages

The action would require the installation of packages from not authenticated sources.

Requires installation of untrusted packages The action would require the installing of packages from not authenticated sources.

Libvlc5 libvlccore5 vlc vlc-data vlc-nox vlc-plugin-notify vlc-plugin-pulse

Close

Also I am having difficulty when installing software using the software center

I have assignments coming up, and I really don't want to stop using Ubuntu so please, please help me sort this out.

Hello Brian Coughlin!

I think you didn't install VLC properly. Uninstall VLC first.

 

Hello Brian Coughlin!

I think you didn't install VLC properly. Open your Terminal and type the following codes:

sudo apt-get remove vlc  (this will remove vlc from your computer)

sudo add-apt-repository ppa:/videolan/stable-daily (this will add the repository to your computer and will get vlc updates from here)

sudo apt-get update (this will get the list of latest updates of your computer including applications)

sudo apt-get install vlc (this will now install vlc to your computer)
