apt.stack256.org

The Debian package repository for every Stack256 product. One source line, one signing key, whatever you install.

Add the repository

curl -fsSL https://apt.stack256.org/stack256-archive-keyring.gpg \
  | sudo tee /usr/share/keyrings/stack256-archive-keyring.gpg > /dev/null

echo "deb [signed-by=/usr/share/keyrings/stack256-archive-keyring.gpg] \
https://apt.stack256.org stable main" \
  | sudo tee /etc/apt/sources.list.d/stack256.list

For Paco specifically, its own installer does all of the above for you: see Stack256org/paco.
