Debian, Devuan + Security >
Problem: Keep an air gapped (airwalled) computer updated via a sneakernet.
This project focuses specifically on Devuan, though it ought to apply any Linux distribution based on Debian.
See also: APT, the package management tool/system for Debian.
Problem: On Devuan-1.0.0-jessie-i386-DVD,
avconv crashes while building a video from an image and audio. It worked until a recent update.
According to old notes,
6:11.9-1~deb8u1 worked. However, I do not know if a more recent version worked before I noticed this problem.
