Updating fedora using yum

The yum (Yellowdog Updater Modified) utility is included with RHEL/Fedora/Cent OS for the management of software.It is an interactive, automated system for maintaining systems using RPM.As typical with new versions of shared libraries where there are differences or additions in symbol versioning between the newer and older libraries (for example, between the newer, standard 5.6 shared client libraries and some older—prior or variant—versions of the shared libraries shipped natively by the Linux distributions' software repositories, or from some other sources), any applications compiled using the updated, newer shared libraries will require those updated libraries on systems where the applications are deployed.And, as expected, if those libraries are not in place, the applications requiring the shared libraries will fail.The GUI front-end remains (pretty much) the same—it’s all still point-and-click goodness.If, however, you are a fan of installing software from the command line, you will notice a quick flash of new text when you go to issue the command: Instead of seeing a list of dependencies, you’ll first get a friendly warning (Figure 1) and then the package will install per normal.

In some cases, this can lead to bugs or unexpected behaviors that vary from the original unpatched versions.

This happened to me when I discovered that my Fedora 18 OS was obsolete (very old indeed) and I tried to upgrade it to the Fedora 20 version.

Fedora 18 doesn’t support the automatic OS upgrade so I had to spend some hours to find information on Internet and create the right DIY solution for my case. ) research I discovered that I was able not only able to upgrade the PC to Fedora 20 but I also found a good “trick” to upgrade to the latest Fedora 21 following in just a couple of steps with the help of fedup and some other escamotages. First, you have to open a Terminal and type: but you will immediately leave the Fedora GUI and so it’s better if you write the below commands on an -old style, paper notepad- to be sure to have all the right information in you hands and correctly manage the upgrade from Fedora 18 to Fedora 20 If you have problems with one or more of your “old” repositories don’t forget to deconfigure them.

A new release of Fedora is out again so it is time to check out the upgrade. The upgrade from Fedora 8 to Fedora 9 is almost exactly like the upgrade to Fedora 8.

Here are the steps you need to do the upgrade from Fedora 8 to Fedora 9: As someone points out in the comments there is a new facility to do upgrades that you can install.
