autopkgtest Rubygems dependency resolution: "No such file or directory - dpkg-parsechangelog"

[Georg Faerber <georg@riseup.net>]

Hi all,

Today I've worked on two packages, ruby-gpgme and ruby-sequel, and ran into the
following error for both of them during autopkgtest:

Checking Rubygems dependency resolution on ruby2.5                           │

autopkgtest [18:15:15]: @@@@@@@@@@@@@@@@@@@@ summary

Any idea where this comes from and how to fix it?

A bit clueless,
Georg
