How can I get a list of repositories 'apt-get' is checking? [closed]

It seems the closest is:

apt-cache policy

As far as I know, you can't ask apt for what their current sources are. However, you can do what you want using shell tools.

Getting a list of repositories:

grep -h ^deb /etc/apt/sources.list /etc/apt/sources.list.d/* >> current.repos.list

Applying the list:

apt-add-repository << current.repos.list

Regarding getting the repository from a package (installed or available), this will do the trick:

apt-cache policy package_name | grep -m1 http | awk '{ print $2 " " $3 }'

However, that will show you the repository of the latest version available of that package, and you may have more repositories for the same package with older versions. Remove all the grep/awk stuff if you want to see the full list.

Try this:

cat /etc/apt/sources.list
