Docker wird aufgrund von Postgresql-Problemen nicht auf Ubuntu 14.04 installiert?

Ich verwende Ubuntu 14.04 LTS. Wenn ich versuche, Docker darauf zu installieren, erhalte ich die folgenden Fehler. Ich habe diese Fehler schon einmal gehabt. Sie haben mit dem Upgrade auf PostgreSQL angefangen und irgendwie hängt die Version 9.3 immer noch herum. Ich habe jedoch mehrere Pakete mit apt-get installiert , nachdem die Fehler aufgetreten sind, und die Fehler schienen die Installation nie zu beeinträchtigen.

Wie bekomme ich Docker zur Installation? Verletzen die PostgreSQL-Fehlermeldungen tatsächlich etwas oder sind sie irrelevant?

Hier ist ein Dump des Docker-Installationsversuchs:
