Maintain package verification

Always keep signature verification enabled in package managers, even in development environments, Docker containers, or when facing initialization challenges. Disabling signature verification creates a significant security vulnerability by allowing potentially compromised or malicious packages to be installed.

Why this matters: Package signature verification is a critical defense against supply chain attacks. Even temporary disabling for convenience can expose systems to compromise.

Example - Do not do this:

# Disable signature checking on pacman because we cannot initialize the keyring
RUN pacman-key --init && pacman -Sy --noconfirm --disable-download-timeout

Instead do this:

# Initialize keyring properly to maintain signature checking
RUN pacman-key --init && pacman-key --populate && pacman -Sy --noconfirm --disable-download-timeout

When facing difficulties with package signature verification, research the proper initialization method rather than disabling the security feature.
