For nm.debian.org, at 2025-08-20: For the past 30 or so months, I have worked with Vladimir Petko on the Ubuntu Foundations team at Canonical. For this past work, Vladimir Petko sent mails using the email address vladimir.petko@canonical.com which is the one they're using on nm.debian.org, and they signed their work and email using a GPG key with fingerprint 8B40 1BEF E41B 434C 9048 432C F63B 668A 969B 07C0. I've made sure that they are able to decrypt encrypted messages sent to this key and that they're able to sign messages with the same key. Due to the long-term interactions we had, I'm convinced that Vladimir Petko as they present themselves on nm.debian.org is the rightful owner of both email vladimir.petko@canonical.com and GPG key 8B40 1BEF E41B 434C 9048 432C F63B 668A 969B 07C0.
