PPA /Personal package archieve

Using PPA we can distribute our own software package to other Ubuntu users, similarly like we download software packages from ubuntu resource. It means ubuntu users can install your software package in the same way as they install standard ubuntu software packages and also receive updates when you make updation to your package.

Package published by you will remain in your PPA untill and unless you remove your package.  Size limit for PPA is 2GB.
1> Firstly you should activate whether your PPA is individual or team PPA. For this you have to do some sort of login in your profile page.
2>After this launchpad generate a key, which is used for package.


** How to install software from PPA ?
1> Visit PPA overview launchpad page and look for heading " Adding this ppa to your system" . Make a note about location which looks like ppa: user/ppa-name.
let us say " ppa: gwibber-daily/ppa
write on terminal : sudo add-apt-repository ppa: gwibber-daily/ppa

2> Your system will now fetch the PPA key.
3> sudo apt-get update
Now you are ready to run sudo apt-get install <sp> (from ppa).


NOTE : Package you are installing from PPA is your own trust towards the publisher.
