Updating ubuntu version

As you can see there are number of possible systems (and the above list is not even close to being all-inclusive).So to make the task of covering this topic less epic, I will cover the Ubuntu and Fedora systems.

updating ubuntu version-1

I will touch on both the GUI as well as the command line tools for handling system updates.

Ubuntu Linux has become one of the most popular of all the Linux distributions.

Apt is a very powerful tool that can completely manage your systems packages via command line.

Using the command line tool has one drawback - in order to check to see if you have updates, you have to run it manually.

The advantage of upgrading is that you get to keep your current configuration as is.

This is often desirable on production environments which you want to keep as stable as possible.

Instead you will know updates are available because the Update Manager will open on your desktop (see Figure 1) as soon as the updates depending upon their type: If you want to manually check for updates, you can do this by clicking the Administration sub-menu of the System menu and then selecting the Update Manager entry.

When the Update Manager opens click the Check button to see if there are updates available.

These guides assumes that the user knows his way on the terminal, as no graphical tools are used.

This said, the steps for executing all the commands are actually copy/pasteable so everyone, from beginner to advanced user running EOL releases of Ubuntu can execute the upgrade(s).

There are is a new tool in development (Ksplice)  that allow even the update of a kernel to not require a reboot.
