10.2 freebsd-update returns cannot open files/.gz: No such file or directory

[Rob Rati]

I'm trying to upgrade my 10.4p13 server to 11.2, and I'm getting a weird set of errors from freebsd-update.  After updating to latest set of patches for 10.4, I run the usual:

freebsd-update upgrade -r 11.2-RELEASE

It goes through its process, downloads patches, etc but I get some errors I'm not sure about:

The following file will be removed, as it no longer exists in
FreeBSD 11.2-RELEASE: /etc/autofs/include_nis
Does this look reasonable (y/n)? n

I'm not sure what is causing those no such file or directory errors though.  I tried cleaning everything out of /var/db/freebsd-update, but they didn't solve it.  There's plenty of disk space in /var as well.

Does anyone know what is causing those errors and how to resolve it?  Where does freebsd-update get the .gz files it could be looking for?
