list all the ppa repositories added to my system

  • 772

How can I list all the ppa repositories added to my system and save it to a .txt file, so that I don't want to spend my time in searching for ppa's for fresh installations and i can just select a ppa line in my .txt file and append to the command sudo add-apt-repository? Also is there any other ways to do this in which i dont want to give the gpg keys manually?

    From How can I get a list of all repositories and PPAs from the command line into an install script?

    Part of the answer looks to have what you are looking for:

    #! /bin/sh 
# listppa Script to get all the PPA installed on a system ready to share for reininstall
for APT in `find /etc/apt/ -name \*.list`; do
    grep -o "^deb http://ppa.launchpad.net/[a-z0-9\-]\+/[a-z0-9\-]\+" $APT | while read ENTRY ; do
        USER=`echo $ENTRY | cut -d/ -f4`
        PPA=`echo $ENTRY | cut -d/ -f5`
        echo sudo apt-add-repository ppa:$USER/$PPA
    done
done

    Save this as listppa.sh

    listppa.sh > installppa.sh

    This creates a script that you can backup somewhere, then run to add your PPAs on a fresh install by simply running:

    installppa.sh

  2. For those who just want to check the PPAs they have installed without actually doing anything with them automatically you can do:

    $ apt-cache policy

    In my system, here's a bit of what it shows:

    % apt-cache policy
Package files:
 100 /var/lib/dpkg/status
     release a=now
 500 http: ppa.launchpad.net/ubuntu-toolchain-r/test/ubuntu/ precise/main Translation-en
 500 http: ppa.launchpad.net/ubuntu-toolchain-r/test/ubuntu/ precise/main i386 Packages
     release v=12.04,o=LP-PPA-ubuntu-toolchain-r-test,a=precise,n=precise,l=Toolchain test builds,c=main
     origin ppa.launchpad.net
 500 http: ppa.launchpad.net/ubuntu-toolchain-r/test/ubuntu/ precise/main amd64 Packages
     release v=12.04,o=LP-PPA-ubuntu-toolchain-r-test,a=precise,n=precise,l=Toolchain test builds,c=main
     origin ppa.launchpad.net
 500 http: ppa.launchpad.net/rael-gc/scudcloud/ubuntu/ precise/main Translation-en
 500 http: ppa.launchpad.net/rael-gc/scudcloud/ubuntu/ precise/main i386 Packages
     release v=12.04,o=LP-PPA-rael-gc-scudcloud,a=precise,n=precise,l=ScudCloud - Linux client for Slack,c=main
     origin ppa.launchpad.net
...

    Quoted from here:

    [apt-cache policy] retrieves priorities associated with each repository resource. From its output, you can infer a list of all available repositories and PPAs.

  3. From my answer on How can I get a list of all repositories and PPAs from the command line into an install script?

    List PPAs in ppa:USER/REPO format:

    grep -E '^deb\s' /etc/apt/sources.list /etc/apt/sources.list.d/*.list |\
  cut -f2- -d: |\
  cut -f2 -d' ' |\
  sed -re 's#http://ppa\.launchpad\.net/([^/]+)/([^/]+)(.*?)$#ppa:\1/\2#g' |\
  grep '^ppa:'

    List all repositories including PPAs in ppa:USER/REPO format:

    Just remove the last grep (don't forget to remove the |\ from the previous line after thesed command).

    See my answer on the other question for full scripts you can save and use, including generating an install script.
