The first option should be the name of a tag, not the name of a build target.
If you want to know the latest build in buildroots for a given build target,
then you should use the name of the build tag for that target. You can find
this value by running '%s list-targets --name=<target>'

More information on tags and build targets can be found in the documentation.
