No. My system didn't have the "postgres" user before installation. I can reproduce this problem like this:
apt-get purge --auto-remove postgresql*; deluser postgres; apt-get install postgresql The error message is exactly the same. Invoking apt-get -f install finishes the installation properly. ** Changed in: postgresql-common (Ubuntu) Status: Invalid => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/735341 Title: package postgresql-common 106ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
