Ubuntu TODO List - POST INSTALL
1. Go to Software Sources > Third Party Sources - select the partner repositories. When you close this, allow to the repositories to be refreshed. Note, this is also where you can add specific update repository information for many third party software packages that Ubuntu does not provide by default. Adding these will allow the Update Manager system also automatically provide updates as they become available for these programs. This is a HUGE advantage of the Ubuntu's updating system that is easily overlooked!
2. Initial update run. Go to Update Manager, click Check to have it check the repositories. Click Install Updates, there will be many updates. Install them all. This will take a while. Reboot the system when this is complete.
3. Go to Add/Remove Applications. Set it to show "All available application" from the drop down menu at the top. Search for "restricted extras". Select the package corresponding to your Ubuntu, Kubuntu, or Xubuntu distribution. Click Apply Changes and go through the install. You get the following from this package:
Commonly used restricted packages -
This package depends on some commonly used packages in the Ubuntu multiverse repository. Installing this package will pull in support for MP3 playback and decoding, support for various other audio formats (gstreamer plugins), Microsoft fonts, Java runtime environment, Flash plugin, LAME (to create compressed audio files), and DVD playback.
Please note that this does not install libdvdcss2, and will not let you play encrypted DVDs. For more information, see https://help.ubuntu.com/community/RestrictedFormats/PlayingDVDs.
4. Note that the above step said that we did not get libdvdcss2 for the playing of encrypted DVDs. For this and other goodies, we add Medibuntu to our repositories list and then install that and other desired packages. Goto https://help.ubuntu.com/community/Medibuntu and follow the directions. Read the ENTIRE page at this site, it will be worth your time. Particularly, do the step for Add Repositories and Add GPG Key first, pick the instructions appropriate for your version of the OS distribution. After you have done these two steps, you will have the Medibuntu repositories available and can add libdvdcss2 and other packages you may want from this repository. The most common packages are libdvdcss2 for playing DVDs and the non-native codecs packages (w32codecs, w64codecs, ppc-codecs) for playing non-native media formats.
5. Now, go do another Update Manager run to check for any final package updates. Reboot. You are done for now.
6. Your system will periodically notify you of updates that are available. Unless you know of a very specific reason not to do so, ALWAYS take these updates. Keeping you system up to date will ensure it has all the latest security, OS, program update and bug fix patches. You may also manually run Update Manager as often as you wish.
