How to create APT repository

• Put .deb file somewhere
• Create an ascii armored gpg key
  • gpg --full-gen-key
  • gpg --armor --export "max.mustermann@gmail.com" > ./KEY.gpg
• mkdir -p ./dists/bullseye/main/binary-amd64
• apt-ftparchive generate ./apt-ftparchive.conf
• apt-ftparchive release -c ./apt-ftparchive.conf ./dists/bullseye/ > ./dists/bullseye/Release
• (cd ./dists/bullseye && gpg --default-key "max.mustermann@gmail.com" --armor --detach-sign --sign --output Release.gpg Release)
• (cd ./dists/bullseye && gpg --default-key "max.mustermann@gmail.com" --clearsign --output InRelease Release)

On client side:

• curl --silent --compressed "https://nqle.github.io/test_ppa/KEY.gpg" | sudo gpg --dearmor -o /usr/share/keyrings/test-archive-keyring.gpg

Misc:

• gpg --armor --export-secret-key 4FD36A1C > private.key
• gpg --armor --export "max.mustermann@gmail.com" > /tmp/home/dockerexchange/pub.key
