Hi all,

I recently came across an issue concerning how the d-apt-keyring package was distributing its keys. While nothing is at risk at the moment, the way the key was distributed make revoking it reliably a problem, so if it were to be compromised in the future - which we all hope won't happen, your system will become vulnerable.

The first step toward getting yourself sorted out it to upgrade the d-apt-keyring package and make sure to revoke the previous key manually using the following command:
$ sudo apt-key --keyring /etc/apt/trusted.gpg del EBCF975E5BA24D5E

I'd like to thank Jordi Sayol who maintains that repository, as he acted quickly to fix the issue and he is maintaining a very convenient repository for us all to enjoy!
