Attacks against GPG signed APT repositories - Packagecloud Blog

It is a common misconception that simply signing your packages and repository metadata with GPG is enough to create a secure APT repository. This is false. Many of the attacks outlined in the paper and this blog post are effective against GPG-signed APT repositories. GPG signing Debian packages themselves does nothing, as explained below. The easiest way to prevent the attacks covered below is to always serve your APT repository over TLS; no exceptions.


This is excellent research. My faith in GPG sigs on packages is well shaken.

Announcing Snappy Ubuntu
Awesome! I was completely unaware this was coming down the pipeline.
A new, transactionally updated Ubuntu for the cloud. Ubuntu Core is a new rendition of Ubuntu for the cloud with transactional updates. Ubuntu Core is a minimal server image with the same libraries as today’s Ubuntu, but applications are provided through a simpler mechanism. The snappy approach is faster, more reliable, and lets us provide stronger security guarantees for apps and users — that’s why we call them “snappy” applications.

Snappy apps and Ubuntu Core itself can be upgraded atomically and rolled back if needed — a bulletproof approach to systems management that is perfect for container deployments. It’s called “transactional” or “image-based” systems management, and we’re delighted to make it available on every Ubuntu certified cloud.
