APT tries to configure PostgreSQL each time I try to install a package

  • 772

I'm getting some strange errors lately whenever trying to apt-get install anything. Here's an example from trying to install fluidsynth.

$ sudo apt-get install libfluidsynth1

I'm running 12.04. What's causing this and how do I address it? It happens for installing lots of things, and seems to suggest I need to initialize postgresql or something. I don't recall having fiddled with postgres, so I'm not sure why this suddenly became problematic.

  1. Best Answer

    Remove/purge postgresql-9.1 and reinstall them:

    sudo apt-get --purge autoremove postgresql-9.1 postgresql

    If you really use postgresql, or another package depends of it, you can install it again

    sudo apt-get install postgresql the-other-program-that-got-removed

    BTW, libfluidsynth1 is already installed, you don't need to install it again.

  2. There's an even easier solution: Postgresql requires the "snakeoil" certificate to exist in order to run: /etc/ssl/private/ssl-cert-snakeoil.key If this was somehow deleted from your system, you can generate a new one with

    # make-ssl-cert generate-default-snakeoil
