I tried to Install PostgreSql in my Ubuntu6.10 Edgy system from downloaded deb packages from <a href="http://packages.ubuntu.com">packages.ubuntu.com</a>, there was one dependancy package called postgresql-commom. when i installed that package, it was infinite time not got completed so i cancelled that process. Thereafter i am not able to install any other packages using GDebi, Synaptic or aptitude. all those components showing error like postgresql-common needs to be re-installed. I can't even install postgresql-common package too. How can i reinstall that package management system lonely or i have to re-install the whole system. Since i have no internet connection in my pc, i have downloaded those packages in a browsing center and used Gdebi installer to install them -- Regards Bose.
