Q1Domain Verified
During a Debian Stable release upgrade, what is the primary purpose of the `dpkg --audit` command, and why is it considered a critical step for specialist maintenance?
To scan the system for outdated security vulnerabilities and suggest immediate patch installations.
To verify the integrity of downloaded package files against their checksums before installation.
To identify and report on packages that are not fully installed, are partially upgraded, or have broken dependencies, preventing potential system instability post-upgrade.
To automatically resolve dependency conflicts by selecting the most appropriate package versions from available repositories.
Q2Domain Verified
In the context of a Debian Stable release upgrade, what is the significance of the `APT::Get::Assume-Yes "true";` configuration directive when used with `aptitude` or `apt` for automated upgrades, and what potential pitfalls does a specialist need to be aware of?
It instructs the package manager to automatically answer "yes" to any configuration file prompts during package installation or upgrades, potentially overwriting custom configurations.
It automatically enables the `unattended-upgrades` service, allowing for fully automated security updates in the background.
It pre-approves the installation of all recommended packages, ensuring a comprehensive software installation without manual selection.
It bypasses all user prompts and confirmations, ensuring a rapid, non-interactive upgrade process by automatically accepting all proposed changes.
Q3Domain Verified
When performing a Debian Stable release upgrade, what is the fundamental difference between `apt upgrade` and `apt full-upgrade` (or `aptitude safe-upgrade` vs. `aptitude full-upgrade`), and why is this distinction paramount for a specialist maintaining production systems?
`apt upgrade` handles minor version updates within the same release, while `apt full-upgrade` is designed for major release upgrades between Debian versions.
`apt upgrade` will never remove packages, whereas `apt full-upgrade` may remove packages to satisfy dependencies for new versions, potentially impacting system functionality if not carefully managed.
`apt upgrade` only installs new packages and upgrades existing ones, while `apt full-upgrade` also removes obsolete packages to resolve dependencies.
`apt upgrade` prioritizes stability by refusing to install any new packages, while `apt full-upgrade` allows the installation of any package required by the upgrade.
