How can I get a list of repositories apt-get is checking

Question

I want a list of repositories in sources list  plus those in sources list d   Can I get this list in a form suitable for setting up another host so it watches the same repositories  Additionally  how do I determine which repository is the source of a package  either installed or available

It s not a format suitable for blindly copying to another machine  but users who wish to work out whether they ve added a repository yet or not  like I did   you can just do  sudo apt update  When apt is updating  it outputs a list of repositories it fetches  It seems obvious  but I ve just realised what the GET URLs are that it spits out  The following awk-based expression could be used to generate a sources list file   cat  tmp apt-update txt   awk   http    gsub  quot   quot    quot   quot    3   gsub  quot   s    quot    quot main quot    3   printf  quot deb  quot    if  4    quot   a-z0-9   quot   printf  quot  arch  quot   4  quot    quot    print  2  quot   quot   3       sort   uniq  Alternatively  as other answers suggest  you could just cat all the pre-existing sources like this  cat  etc apt sources list  etc apt sources list d    Since the disabled repositories are commented out with hash  this should work as intended

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    gt  gt  current repos list  Applying the list  apt-add-repository  lt  lt  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  quot   quot   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
