• [nitpick] The error message "-control-file flag is empty." is unclear. Consider changing it to "The -control-file flag must be provided and cannot be empty."

action.Fatalf("%s", "-control-file flag is empty.")

I think we should do a better job separating extension version, Debian package version, and git tag name in both terminology and code. For example, it looks like parseVersion tries to parse everything.

Actually, let's remove all checks for default_version from that PR. We will introduce them later, once we have a better understanding of it all.

For release tags, it's not necessary to use default_version.

For PR, branch builds etc, upstream version need to start with some digit. I think using default_version for that makes sense for the time being.

The upstream_version must contain only alphanumerics 6 and the characters . + - ~ (full stop, plus, hyphen, tilde) and should start with a digit.
