I was installing PostgreSQL 9.4 and pgAdmin on my Ubuntu 12.04 and after that I needed to install Postgis extension for Postgres as well. Before the Postgis step all was fine. There I tried with compiling the source code as well as with
dpkg -i .deb method to install and both gave an error about a file missing - libpq-fe.h. I found out it's in a libpq-dev package, so did
sudo apt-get install libpq-dev. This returned me that this package is already installed. Though a folder in which the file libpq-fe.h (and others) should be was empty. So my guess was to remove libpq-dev and install it again. I tried both with
sudo apt-get remove ... and
sudo apt-get remove --purge ....
From here the package manager broke and right now any attempt to install a package (below Wine, just for example) or do a
sudo apt-get upgrade returns:
adambo@adam-pc:~/Downloads/postgis-2.2.2$ sudo apt-get install wine Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: libpq-dev : Depends: libpq5 (= 9.1.20-0ubuntu0.12.04) but 9.5.3-1.pgdg12.4+1 is to be installed postgresql-server-dev-9.4 : Depends: libpq-dev (>= 9.4~) but 9.1.20-0ubuntu0.12.04 is to be installed wine : Depends: wine1.4 but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
What I've tried:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get clean
sudo apt-get remove
sudo apt-get autoremove
sudo apt-get install -f
Some returned regular results (or nothing), but some returned same as in
I also tried to remove libpq-dev and libpq5 packages, but any attempt resulted in the
code above again.
sudo apt-get install -f gives me:

Y dpkg: dependency problems prevent configuration of libpq-dev: libpq-dev depends on libpq5 (= 9.1.20-0ubuntu0.12.04); however: Version of libpq5 on system is 9.5.3-1.pgdg12.4+1. dpkg: error processing libpq-dev (--configure): dependency problems - leaving unconfigured No apport report written because MaxReports is reached already Errors were encountered while processing: libpq-dev E: Sub-process /usr/bin/dpkg returned an error code (1)
What could I do to at least restore apt-get functionality?
