I am trying to find out how software upgrade works in Ubuntu LTS version.
Let's say I am using Ubuntu LTS xx.xx. At the time of release, user can install PHP 5.3 and Python 2.6 (this is just an example). After 2 years, the available stable Major release of PHP and Python are 5.5 and 2.7 respectively (this is also an example only).
Let's say I run these commands in Ubuntu LTS:
apt-get update apt-get upgrade
Will it upgrade the PHP and Python version to the latest available stable Major release, i.e. 5.5 and 2.7? Or it will only upgrade to the new Minor release, e.g. 5.3.2 and 2.6.3?
