On 18.04 I have the backports enabled in /etc/apt/soures.list. My questions are:
- How can I find out which packages are installed from backports? The tips from https://serverfault.com/questions/109442/how-can-i-list-all-installed-packages-from-lenny-backports for Debian Lenny do not work.
- I want to go from backports to the normal repository. How can I do it without a lot of commands? By doing this I can compare the versions and decide if there would be configuration/downgrading issues.
