I just want to install VLC latest from 12.04 LTS to 10.04 LTS How to do it?
As of today, the latest version of VLC available now is 2.0.4, which is the same one available in Ubuntu 12.10, so if you upgrade to Ubuntu 12.10, you will have the latest version of VLC
Since you are in 10.04 release, the VLC version you can get from Synaptic is only the one in 10.04 repos.
If you want a more recent version of VLC, you can get the .deb package from the this website.
But the problem is that the dependencies of the latest VLC version may not be present in your current 10.04 repos. In that case, you would have to go manually install them and then their dependences and so on.
This defeats the purpose of having a package management system.
So, if you want to use a latest version of VLC (say available in 12.04 repos), I suggest you upgrade your system to 12.04.
One of the methods of installing a software not in the standard ubuntu repos but through apt-get is by using a Personal Package Archive (ppa). All ppa's are hosted on http://launchpad.net. On searching, i found that one of the ppa has the version of vlc that you require (vlc-2.0.4 ). https://launchpad.net/~n-muench/+archive/vlc.
This has all the dependencies vlc-2.0.4 needs.
Add this ppa to your system like so:
Then update your sources by:
Then install again:
That should do it. I tried and it works. You can install from other ppa as well but make sure it builds successfully by checking in the right hand side of the ppa's main page.
