Just wanted to share a problem I ran into and how I fixed it.
When running the upgrade installer, it hangs with an obscured error message and prompts for a port number. It is apparent that the installer was checking whether port 443 was available for use by a VMware process, and discovering a process was already using it is asking for an alternate port number.
It turned out that the installer hadn't shutdown vmware-hostd properly. The document linked below shows how to fix the problem:
Recovering from error message during Workstation upgrade on Linux host when port 443 is unavailable.
