Also applies to "no candidate version" packages. I suspect the package list gets checked through twice instead of once.

[Matthew Woerly (nattgew)]

I can confirm this behavior in the latest Hardy.

[Daniel Hartwig (wigs)]

Due to the internal processing model of command-line actions, this applies to most warnings and status messages that can occur during install, upgrade, remove, forbid-version, etc.

Other examples:

Couldn't find any package whose name or description matched "foo"
Package foo is not upgradable, cannot forbid an upgrade
