How can I list all packages I've installed from a particular PPA?

Question

How can I list all packages I've installed from a particular PPA? Command-line answers preferred.

Related question: how can I list all installed packages that are not available from the main Ubuntu archives, and also see which repositories they came from? (If I knew the answer to this question, I could grep that list for a particular PPA name to find out the answer to my first question.)

Answer 1

Simply expand the "Installed Software" item in Ubuntu Software Center. You'll see a list of all the different repositories that you've enabled. Clicking on the repo will show you the packages you've installed from each.

Answer 2

Open Synaptic Package Manager and click the "Origin" button on the left sidebar. It will list your sources. Select a source to see the available/installed packages.

Answer 3

There seems to be no record of the origin of an installed package.

If you are fine with getting the location from whence a package of the same name would be downloaded from, this is available through apt-cache policy. The following (rather ugly) script does the trick for me:

LC_ALL=C dpkg-query --showformat='${Package}:${Status}\n' -W '*' \
  | fgrep ':install ok installed' \
  | cut -d: -f1 \
  | (while read pkg; do 
       inst_version=$(apt-cache policy $pkg \
                                | fgrep Installed: \
                                | cut -d: -f2-); 
       origin=$(apt-cache policy "$pkg" \
                          | fgrep " *** ${inst_version}" -C1 \
                          | tail -n 1 \
                          | cut -c12-); 
       echo $pkg $origin; 
     done)

Note that it's quite fragile, as it makes assumptions about the output of apt-cache policy, which might change across versions...

Under Quantal (12.10), the space in the origin line needs to be removed.

LC_ALL=C dpkg-query --showformat='${Package}:${Status}\n' -W '*' \
 | fgrep ':install ok installed' \
 | cut -d: -f1 \
 | (while read pkg; do 
   inst_version=$(apt-cache policy $pkg \
                            | fgrep Installed: \
                            | cut -d: -f2-); 
   origin=$(apt-cache policy "$pkg" \
                      | fgrep " ***${inst_version}" -C1 \
                      | tail -n 1 \
                      | cut -c12-); 
   echo $pkg $origin; 
 done)
