[Bug 1728193] [NEW] Can not upgrade from 17.04 to 17.10 using software updating tool

[Scott]

Public bug reported:

I wanted to update my distro version from 17.04 to 17.10 and an error
occurs when using the software updating tool. It starts out just fine
but during the second stage it goes into error when calculating.
