A couple of months ago I installed Postgesql 9.1 and Postgis 2.0 on my Ubuntu 12.04 server. Now I can't do any apt-get upgrades or installs because of this installation with broken libgdal1 dependencies. I've tried sudo apt-get autoremove and sudo apt-get install -f like it suggests but it won't work and just gives me the following errors:

dpkg: dependency problems prevent configuration of postgis: postgis depends on libgdal1 (>= 1.9.0); however: Package libgdal1 is not installed. 
    postgis depends on postgresql-9.1-postgis; however: Package postgresql-9.1-postgis is not installed. 
dpkg: error processing postgis (--configure): dependency problems - leaving unconfigured 
No apport report written because MaxReports is reached already 
Errors were encountered while processing: postgis 
E: Sub-process /usr/bin/dpkg returned an error code (1)

I feel like I'll need to backup and restore my database just to get apt-get working again which is absolute craziness. These are the times when I really miss working with Windows installations. Any help/suggestions would be greatly appreciated.
