Updating fedora 8 to fedora 9
Now some updates may require either you to log out of your desktop and log back in, or to reboot the machine.
There are is a new tool in development (Ksplice)¬† that allow even the update of a kernel to not require a reboot.
For some new users this left their machines outdated or without applications they needed. Now Linux is exponentially more user friendly - to the point where so much is automatic and ¬†that today's Linux hardly resembles yesterday's Linux.
Of course, at the time, most everyone trying their hand at Linux knew they were getting into something that would require some work. But even though Linux has evolved into the user-friendly operating system it is, there are still some systems that are fundamentally different than their Windows counterparts.
In fact, some distributions are distinctly different down to the type of file types they use for package management.
As you can see there are number of possible systems (and the above list is not even close to being all-inclusive).
There is one thing to understand about updating Linux: Not every distribution handles this process in the same fashion.
If you installed Docker using the convenience script, you should upgrade Docker using your package manager directly.
There is no advantage to re-running the convenience script, and it can cause issues if it attempts to re-add repositories which have already been added to the host machine.
When the Update Manager opens click the Check button to see if there are updates available.
The updates will proceed and you can continue on with¬† your work.
