[DRE-maint] Bug#918916: Unicorn not reporting proper version for gemfile?

[Justin Hallett]

Package: unicorn
Version: 5.4.1-1

Could not find gem 'unicorn (~> 5.1)' in any of the gem sources listed in your
Gemfile.


I tried to update the Gemfile, I even tried making the depend '>= 0’. But then dependancy have depends on it like

Processing triggers for gitlab (11.5.6+dfsg-1) ...
Bundler could not find compatible versions for gem "unicorn":
  In Gemfile:
    unicorn

    unicorn-worker-killer (~> 0.4.4) was resolved to 0.4.4, which depends on
      unicorn (< 6, >= 4)


So I rolled back to unicorn_5.4.0-1+b1_amd64.deb and it works again.  Seems something is wrong with how unicorn 5.4.1 reports its version.
