For good or bad, i was able to overcome the yum update issues using go_jesse statements above.
Thanks Jesse
Here are my steps
From the server-manger panel, using a web browser to access
http://ipaddress/server-managerGoto Software installer
Select Change software installer settings
Select all repositors except these two, CentOS-os and SME Server-updates testing
Click on the save button
Click on the Date and Time
Click on Software installer
Install any packages
If packages neeed to be installed then click on Reconfigure
The computer will reboot and reconfigure
Let the computer reboot and settle down
From a command prompt on the console or a console using a ssh program
Enter
top -l
If you do not see yum from the display after awhile, press ctrl-c to exit out of the top program
Enter
yum clean all
yum --enablerepo=smeupdates-testing install e-smith-samba
Now you should at this point get a Y to continue, enter the Y
After the updates enter
signal-event post-upgrade; sudo signal-event reboot
The computer will reboot and reconfigure.
Get back to the console of the server by whatever means you did before.
Enter
top -i
Wait to see no more yum processes running, then use ctrl-c to exit out of the top program
Enter
yum clean all
yum update
At this point you should no longer see any more updates to be installed.
Go back into the server-manager panel using a browser as you did before and into the Software installer.
Select select Change software installer settings
Select all repositors except SME Server-updates testing
Click on the save button
Click on the Date and Time
Click on Software installer
Install any packages
If packages neeed to be installed then click on Reconfigure
The computer will reboot and reconfigure
Let the computer reboot and settle down
At this point, the computer should have the updates installed
To check for more updates, get back to a console
Enter
yum clean all
yum update
You should see no more updates needed
