Processing triggers for postgresql-common ... debconf: DbDriver "templatedb": /var/cache/debconf/templates.dat is locked by another process: Resource temporarily unavailable dpkg: error processing postgresql-common (--unpack): subprocess installed post-installation script returned error exit status 1
This seems to be a bug in how update-manager handles debconf?
