IMPORTANT: VMware removed the ESXi 7.0 Update 2 offline and online depots from all sites on March 12, 2021 due to an upgrade-impacting issue. Build 17867351 for ESXi 7.0 Update 2a replaces build 17630552 for ESXi 7.0 Update 2. All Components and Bulletins in the ESXi 7.0 Update 2a build are updated and replace the Components and Bulletins from the ESXi 7.0 Update 2 build.
To upgrade to a fixed version with vShere Lifecycle Manager or with an offline depot, use ESXi 7.0U2a (Build 17867351)
Note: You might have to perform "Sync Updates" in LifeCycle Manager (7.x) or "Download Now" in Update Manager (6.x) to update the Patch metadata if the 6.5 latest patch EP24 (18071574) is not showing in Updates (screenshot below).
If you are not able to update your ESXi hosts at this time, the workarounds detailed in KB 1025757and KB 76372 can be applied to all your ESXi hosts
