[Bug 1510841] Re: "Could not calculate the upgrade" due to multiple metapackages being installed

[Derek Roberts]

Following the instructions in this thread
https://ubuntuforums.org/showthread.php?t=2382832 to point
/etc/apt/sources.list to the moved zesty sources allows the process to
resume.

Surely the upgrade script could be modified to check if the current rev
sources have been move to "old" and re-point the apt sources there?
Otherwise if you don't know to upgrade within set time you get hosed
into mysterious upgrade fail hell
