- "apt-cache show package" succeeds as well if package is listed as (optional) dependency or conflict by another package, hence is not a 100% reliable measure.
- There is no command which explicitly checks which package/name can be selected by apt-get for install. An install simulation/dry-run is possible as it was before Pi-hole v5.1, or the whole package cache can be scraped, which is still the less time consuming solution.
- Allow to succeed if another package "provides" it, like "php7.3-apcu" provided by "php-apcu" or "awk" provided by "mawk" and "gawk", in which case the non-virtual package is selected automatically by apt-get.
