Re-reading your error message:

  # psql -U pgsql -d gdt -c 'SELECT postgis_extensions_upgrade();'
  NOTICE:  Updating extension postgis 3.6.0rc1
  ERROR:  extension "postgis" has no update path from version "3.6.0rc1" to version "ANY"

If you had 3.6.0rc1 installed you also had the 3.6.0rc1--ANY file
(update path from "3.6.0rc1" to version "ANY").

That file must have been removed by your package manager upgrade procedure,
which replaced it with 3.6.0rc2--ANY, is this what happened ?

Your subsequent call to `postgis install-extensions-upgrade 3.6.0rc1`
created that missing file again.

There's no way out of including an upgrade path file for each and
every known release of PostGIS unless those packages become smarter
and decide which upgrade paths to support based on some knowledge
they have about which possible versions were ever shipped...
