bug: Misleading error message when no successors available #1022
Description
I have a scenario setup with 6.0.1 installed, where I updated the spec.version to 6.0.0 with upgrade policy enforcement enabled.
I got the following error message:
message: 'error upgrading from currently installed version "6.0.1": no package
"cockroachdb" matching version "6.0.0" found'
This makes it sound like:
- there just isn't a 6.0.0 version in the catalog
- if there was a 6.0.0 version (there is), the upgrade would proceed (it doesn't, because 6.0.0 is not a successor)
A good initial improvement would be something like:
message: 'error upgrading from currently installed version "6.0.1": desired package "cockroachdb" with version range "6.0.0" does not match any successor of "6.0.1"
It would be sugar on top if we listed the best successor in both the z stream and y stream. For instance:
message: 'error upgrading from currently installed version "6.0.1": desired package "cockroachdb" with version range "6.0.0" does not match any successor of "6.0.1". Highest version successors of "6.0.1" are "6.3.11" (y-stream) and "6.0.10" (z-stream)
