Package dependencies

I use this page to track custom built deb-packages that I have built as a dependency for Immich Distribution. The packages are build in clean containers targeting Ubuntu 22.04.

Repository

deb [arch=amd64 signed-by=/etc/apt/keyrings/nsg.gpg] http://apt.nsg.cc jammy main

You find the key at snap/keys/, you need to dearmor it with cat 8FA0B5E3.asc | gpg --dearmor -o /etc/apt/keyrings/nsg.gpg

Immich uses sharp for image processing. Sharp uses libvips, and libvips has imagemagick as a backend and uses it as a fallback engine if it can't handle an image format directly.
