Currently I have installed Debian Lenny on virtualized server provided by my local ISP. I can't upgrade it, can configure it however I want, to Squeeze but I need newest package versions provided by Squeeze repository.
If I update /etc/apt/sources.list to Squeeze and then install, say potgresql, will it work correctly or system will be broken afterwards. Troubles can be with package dependencies.
Are there any other sources that provide new versions of software (dotdeb maybe)? Or how would you solve this problem?
Asking provider to upgrade is no option, tried that. Changing provider also not an option :p
I'm new to Debian but know my way around linux pretty well.
Note: This setup is for testing only, may be used as development server later, once I install required packages.
