The option to select LTS notifications should be masked in non-LTS versions

Status changed to 'Confirmed' because the bug affects multiple users.

This was discussed in #ubuntu-meeting on 20180726 and the solution presented was to have the release upgrader do the "right" thing by upgrading your system until you hit an LTS. So if you are running zesty and have "Prompt=lts" set then it would upgrade you to artful, then bionic and then stop because bionic is an LTS release.

Thanks, Brian. That sounds reasonable and would---in fact, accomplish what
I _thought_ it was supposed to do when I was setting it on end-user
installs so that I could expose features and functionality of a non-LTS
version while assuming it would pause at the next LTS.

I appreciate you feedback. Any ideas when this might be implemented? Is
there a bug I can track to be notified of the functionality changes?

This would actually need to be fixed in update-manager's UpdateManager/Core/MetaRelease.py around where the prompt checks are done.

This bug was fixed in the package update-manager - 1:18.10.4

---------------
update-manager (1:18.10.4) cosmic; urgency=medium

  [ Łukasz 'sil2100' Zemczak ]
  * Ignore Prompt=lts for non-LTS series. This way if a user is on a non-LTS
    and has Prompt=lts, he/she will be upgraded to the next supported series
    until finally reaching an LTS. (LP: #1783328)
