Trouble installing postgresql

[Dave De Graff]

I get the following error when trying to install postgresql. The packages listed as required dependencies are all available. Does anyone know why apt is not simply installing these along with postgresql?   Thanks,   Dave De Graff   root@host:~# apt-get install postgresql Reading Package Lists... Done Building Dependency Tree... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.   Since you only requested a single operation it is extremely likely that the package is simply not installable and a bug report against that package should be filed. The following information may help to resolve the situation:   Sorry, but the following packages have unmet dependencies:   postgresql: Depends: libkrb5-17-heimdal (>= 0.4e-23) but it is not going to be installed               Depends: postgresql-client but it is not going to be installed               Depends: libpq3 (>= 7.3.1) but it is not going to be installed E: Sorry, broken packages root@host:~#
