passwd and sudo where available but not installed. So when I ran reinstall with them it never installed them. Once I made that change everything seems to work and run as expected.

@tikicoder Thanks for your contribution! It seems odd that the packages were not there, BUT, it does not hurt to use the install method instead of the re-install anyway.
