Udating to latest ubuntu version
However, if you’re currently running Ubuntu 10.04, you won’t see an option to automatically download Ubuntu 10.10.
This is because Ubuntu 10.04 was the most recent Long Term Support (LTS) edition of Ubuntu.
Ubuntu is designed to make it easy to install the latest versions of all of your software.
Effectively, this means that the LTS release comes supported with bug fixes and security updates for as long as 5 years, hence users would not have the privilege of being alerted through popups urging them to install the latest available version. While this phenomena does not affect usage of regular Ubuntu releases, those users who are tempted to access updated features and the newest of applications have the option to upgrade the existing Ubuntu LTS on their system into the next available version, as explained below.
Important: Before proceeding to upgrade, make a full backup of your data to an external device (USB stick or CD/DVD).
Remember to re-enable them once the upgrade is finished.
Once everything’s finished, you’ll be asked to reboot your system to complete the upgrade.
This means it will receive security updates for 3 years, unlike standard releases which receive updates for just 18 months.
However, if you want to always be using the latest version with the newest look and feel, you’ll likely be ok switching to standard releases and upgrading to the latest versions.
You need NOT to make any changes to this file until and unless you need extra repositories for your setup.
Type the following apt-get command: in addition to performing the function of upgrade, also intelligently handles changing dependencies with new versions of packages; apt-get has a “smart” conflict resolution system, and it will attempt to upgrade the most important packages at the expense of less important ones if necessary. The /etc/apt/file contains a list of locations from which to retrieve desired package files. It works like Microsoft or Red Hat update manager i.e.
Putting the new PPAs in after the update (hard to call some of these things "upgrades"). On Ubuntu dist-upgrade is within the same release - newer kernels usually.
I run a dist-upgrade as part of my weekly patching for 20 servers here - no chance it will migrate from LTS-to-LTS.
# lts - Check to see if a new LTS release is available.
