Web searches have not been helpful for these: 1-Which of apt* returns version numbers along with package names, one line per result, when searching? (in openSUSE, versions are returned by zypper search via the -s switch (one line per package))
2-http://ftp.debian.org/debian/pool/main/f/firefox-esr/ apparently has what I want for Stretch, esr52.9 by whatever name (Firefox-ESR or IceWeasel). How can I get the cmdline package management system (apt-???) to tell me which I can choose from other than installed and latest? Searches tried (e.g. apt-show-versions; apt list -a; apt-cache madison) only show 45.x (installed) and 60.3 (available). -- Evolution as taught in public schools is religion, not science.
