Is there an alternative for 'ppasearch' in newer versions of Ubuntu?

If you're looking to search for a PPA which contains a certain package, you can use the PPA search feature in Y PPA Manager (by WebUp8).

  1. Install it with these commands:

    sudo add-apt-repository ppa:webupd8team/y-ppa-manager
    sudo apt-get update
    sudo apt-get install y-ppa-manager
    
  2. Run it by searching for Y PPA Manager in the Dash.

  3. Click on the "Search in all Launchpad PPAs" button.

  4. Enter your admin password if prompted.

  5. Enter the package name you want to search for.
    Enable the "Basis search" if you want it to go faster, but with less info

  6. Click "OK". A notification will appear informing you that the search has started,
    wait for a new window with PPAs to appear.

  7. You can then choose to add a PPA and other actions.

As a side note, Y PPA Manager also includes a handy utility called update-ppa. It's like apt-get update, but only for one PPA.

Usage:

sudo -H update-ppa ppa:webupd8team/y-ppa-manager

(replace ppa:webupd8team/y-ppa-manager with the PPA, with a similar format)
