How can I get a list of packages installed (excluding dependencies) on an Ubuntu installation that I cannot boot into?
Something like this answer aptitude search '~i!~M' but reading packages from an external HDD on which Ubuntu 15.04 is installed.

Dependencies are packages too, sure you want them excluded? – mikewhatever Aug 20 '16 at 09:13

Yes. I will use the list to help me install software for a new 16.04 installation. – Edan Aug 20 '16 at 09:43

The answer provided by knudfl in 2010 on http://www.linuxquestions.org/questions/debian-26/getting-list-of-installed-packages-from-a-dead-system-811288/ can still help you:
- mount the disk of the dead system (e.g. on /media/disk )
grab the list of installed programs:
ls /media/disk/var/lib/dpkg/info/ | grep list
