error on/while installing packages package libjack-jackd2-0:amd64 1.9.10+20150825git1ed50c92~dfsg-1ubuntu1 failed to install/upgrade: package libjack-jackd2-0:amd64 is already installed and configured

I had selected a variety of MIDI-related packaged in synaptic to install. I saved markings, to change apt config (for speed limit) and then reopened synaptic, and continued from there. It appears a post-install script may be recursing on some way?
