Hi, Stefano.



Don't pay too much attention to the SL version number in the grub2 boot 

menu. These labels are set when the kernel is installed or updated, and 

don't necessarily reflect the SL version you're currently running. If 

you updated the kernel to the latest version (3.10.0-957.1.3.el7) before 

upgrading from 7.5 to 7.6, there would not have been any further kernel 

upgrade during the 7.6 upgrade, so no update to the grub2 menu. All 

you're choosing from the boot menu is a particular version of the 

kernel, and kernel versions are more or less independent of the SL 

release number (or at least the minor version number). Any "3.10.*.el7" 

kernel version should work with any SL 7.* release.



The more important indicator is the value in the file 

/etc/yum/vars/slreleasever. If it's 7.6 or 7x, then yum will grab the 

latest SL 7.6 updates and you should be fine. If it's gone back to 7.5 

for any reason, then you may have a problem requiring another attempt at 

upgrading to 7.6. But even so, it's highly unlikely that all the RPM 

package that got installed during the 7.6 upgrade got downgraded to the 

7.5 versions, as yum doesn't usually downgrade unless explicitly told to.
