Unfortunately, that link doesn't work.
Ya know...that's about how my entire day has gone today...sigh
Try this instead:
Update arrived. That is fine! This repair a few very annoying bugs. Thank you!
But during I do the update there are a few questions:
*Doc says 'update the systen before doing the upgrade'. Why is there no hint/or question in the installer? At least a litte sentence should be there.
*No only related to GMS: Why are so differnet ways to install parts of the same product line? Most of the ex Novell-SW is based on Linux (rpm). Build a repository store and use always the same manner to install/update the software.
I updated my SLES server last night before updating GMS to 18.2.1. I noticed that the installer did do a check for some packages and stated that they were up to date so nothing needed to be done. My guess is that the installer will get the needed updates, but the docs just recommend doing it yourself prior.
