Last week, I attended DebConf 17 in Montr??al, returning to DebConf for the first time in 10 years (last time was DebConf 7 in Edinburgh). I gave a talk entitled ???A Debian maintainer’s guide to Flatpak???, aiming to introduce Debian developers to Flatpak, and show how Flatpak and Debian (and Debian derivatives like SteamOS) can help each other.
