How to update your ESXi 6.0 host the easy way
Great news, this article has already been written by Vladan Seget, it's good to go as-is!
How do I know? Because I tested it, updating to ESXi 6.0.0 build 2715440, and recorded each and every step of the process in the short video below.
JUL 21 2015 Update - I've now tested updating to ESXi 6.0.0 build 2809209, and have updated the article below.
So if you only have a single ESXi 6.0 host to patch, especially to handle the CBT bug explained here, you'll see this can all be done without installing and configuring VMware Update Manager.

How to Install latest ESXi VMware Patch – [Guide]
by Vladan Seget on May 18 2015
Detailed step-by-step TinkerTry walk through

In this video, you'll see these 4 basic steps (on an earlier build, but the procedure is the same):
-
Enter ESXi Maintenance mode
-
Download
ESXi600-201507001.zip
, upload to ESXi using Datastore Browser - use PuTTY to SSH in and type this install command:
esxcli software vib install -d /vmfs/volumes/SSD3-256GB/patch-directory/ESXi600-201507001.zip
substituting the SSD3-256GB part with the full path to your .zip file. Tab/type-ahead is your friend!
-
reboot
- verify the new build that's seen as the system reboots. After boot, an alternative is to use the vSphere Web Client, select the host, select Summary, then select the Configuration pane.
Before the upgrade, using the March 12 initial release of vSphere 6.0 it shows:
VMware ESXi, 6.0.0, 2494585
After this patch and the reboot, it should show:
VMware ESXi, 6.0.0, 2809209

VMware Update Manager
Better suited for automating many ESXi host upgrades.
JUN 15 2015 Update
Thanks to Thomas's comment below, who mentions Andreas Peetz excellent alternative approach that is even easier (requires outbound access to the internet from the ESXi server):
