Does changing my Launchpad GPG key require any changes to my PPAs?

  • 772

I've lost my GPG key which was used to sign my PPA. So, I generated a new key and deactivated old one in Launchpad.

Now, I would like to change the key which is used to sign repository. Currently the ppa is unavailable duo to invalid GPG signature.

My PPA: https://launchpad.net/~soroush-r/+archive/geopsy-deb

launchpad

    Your GPG key with Launchpad is only used to sign the PPA uploads, NOT the generated PPA packages:

    Launchpad generates a unique key for each PPA and uses it to sign any packages built in that PPA.

    Any loss/compromise of your GPG key doesn't affect the PPA signing key, and AFAIK it's not possible to change that key even if you wanted to, without creating a new LP account.

    I was just able to successfully add your PPA:

    Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /tmp/tmp.Dwh5o34jwl --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver hkp://keyserver.ubuntu.com:80/ --recv AF89B3310ED9C8EAE449CA2694932D568ED3C834
gpg: requesting key 8ED3C834 from hkp server keyserver.ubuntu.com
gpg: key 8ED3C834: public key "Launchpad PPA for Soroush Rabiei" imported
gpg: Total number processed: 1
gpg:               imported: 1  (RSA: 1)

    To resolve any local problems you're having, simply re-add the PPA signing key with:

    sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 8ED3C834
