I have found the following: http://unix.stackexchange.com/questions/249330/centos-7-2-now-to-update
CentOS 7 (through and including 7.1) offered the |Applications | System Tools | Software Update| applet. This applet allowed users to update CentOS 7. Where is the applet in 7.2 v1511? I do not see that anymore.Yes, I know of |yum -y update|. I executed the |yum -y update| command, which is how I got from CentOS 7 to CentOS 7 (7.2 v1511).
1 AnswerThis is a bug in the Upstream(Redhat) which has been reported: https://bugzilla.redhat.com/show_bug.cgi?id=1290868
You can solve this issue by installing the |gnome-packagekit-updater| package with this command.
|sudo yum install gnome-packagekit-updater |Once this package is installed you will find the ICON where it used to be. i.e: Applications | System Tools | Software Update
You can also start the GUI Updater from command line once it is installed by invoking this command:
|sudo gpk-update-viewer | End quote.I understand that the above applies to CentOS 7.2, but SL 7.2 and all other RHEL re-distributions, not binaries licensed from Red Hat for fee, now must go through the "Red Hat subsidiary" CentOS for the source from which to build a distro (e.g., SL 7.2) . Thus, the same procedure should work if one knows how to point the upgrade path to a local DVD. Note that I use MATE, not Gnome, as my primary GUI system. Must I use Gnome for the above correctly to function, or will an invocation from a command line in a MATE terminal GUI application suffice?
Has anyone done the above, and, if so, what cautions (warnings, "gotchas") are needed?
Note that I have attempted to install the above gnome-packagekit-updater with the following error diagnostics and failure:

Error Summary ------------- [root@jb344 ykarant]# Any assistance would be appreciated. Yasha Karant On 02/16/2016 11:15 PM, Yasha Karant wrote:
I have burned the current production SL 7.2 4 Gbyte install DVD. The DVD boots but does not seem to have an upgrade option, only an install option. Note that I plan to overwrite all files/partitions used by the system (but not /home , /opt , /usr/local that is a separate partition from /usr, and the like).Currently, a number of add-on repositories (e.g., elrepo) for 7.1 are searched by the software installer. Will these be saved and used for 7.2 or must these manually either be saved or reinstalled after the 7.2 update?Are there instructions (URL?) for the upgrade, or is there a mechanism to invoke the DVD-based installer to do the update? I do not want to use an Internet update because of the latency -- I want to do the upgrade from local (DVD) media. Is this possible?Yasha Karant
