This has been heavily discussed over in the CentOS lists. The
dependencies for updating a RHEL server to RHEL 7 are potentially
dangerous enough that RHEL is recommending against it. They provide a
utility, but it's proven pretty fragile if you've been installing
non-standard components, as I've seen you attest to various times on
this list. And the regression testing for that kind of major, major
upgrade to systemd based service management and the re-architecture of
NetworkManager and the switch from "/bin" to a symlink to "/usr/bin"
is just plain nasty to cope with.

So bringing the published tools into Scientific Linux compatibility is
a serious, serious potential for one heck of a lot of work.

If your host is already SL 7.1, you should be able to simply use the
"scientific/7/" repos to get the updated

Those are mostly using "epel/7/", "elrepo/7/", etc., and should not be
a problem if you are already on SL 7.x.

If you;re already on SL 7.x, you should be able to mount the CD and do
"yum -y update /mnt/[whatever]/Packages/sl-release*.rpm" and get most
of the changes availabale.

7.2 update instructions [2]

[Yasha Karant]

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).

This 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:

Any assistance would be appreciated.
