PPAs and Repositories

           There are time many new users to Linux will find that a certain software is not available to them when they try to download it through the terminal.  The only other way to install the app would be to download the .tar files and compile them which in turn is quite a tedious job sometimes.
          Using PPAs and and repositories of other unknown or upcoming software that are not listed on the Software centre. There are many ways to add repositories but the simplest and easiest way is to use the Terminal.
 Suppose you want to add a repository for the FuseEXFAT drivers that are not available in the installation disc of ubuntu due to some patent issues with Microsoft, you will need to add the repository for the drivers manually before you can download and install them.
    To add a repository through the terminal, type the code below on your terminal and type your password when asked.

sudo add-apt-repository ppa:relan/exfat

    Whatever software repository that you are adding from, the lines below would remain the same.

sudo add-apt-repository

    The lines below would vary depending on the developer and it is not difficult to find the ppa codes, all you need to do is a little bit of googling. 

ppa:relan/exfat

 After this step, you only need to update the repository by typing

sudo apt-get update

Finally, install the app or in this case the driver using the normal sudo apt-get install command as usual. In case you want to install the drivers for EXFAT file system on windows the codes are below.

sudo apt-get install fuse-exfat
