Package: postgresql-common Version: 165+deb8u2 Both postgresql-common and libpq-dev install the file /usr/bin/pg_config . That's a bug, isn't it? dpkg --install seems to think so.
This was not a problem for me before an attempted update a few days ago; Now I have broken dependencies that I cannot fix because I cannot install the current libpq-dev because of the file conflict. I don't know what changed. -- Bryan Henderson San Jose, California
