Admin notes: 

Self extracting installer. Run it under sudo and it will prompt for an install location. Target should be /usr/local/shared/ucsf-chimera/X.YY/

It will then ask:

Install desktop menu (icon has to be done by user)? yes

Install symbolic link to chimera executable for command line use in which directory?
    0 -- no link
    1 -- /usr/local/sbin
    2 -- /usr/local/bin
    3 -- /usr/sbin
    4 -- /usr/bin
    5 -- /sbin
    6 -- /bin
    7 -- /snap/bin
[hit Enter for default (0)]:

Output then includes:

To (re)install desktop menu and icon later, run:

    /usr/local/shared/ucsf-chimera/1.16//bin/xdg-setup install

If run as root, then it only installs the menu
(for all users).  Otherwise, it installs the icon
(and menu, if need be) for the current user.

In total, took less than 21m27s (some of the time was waiting at prompts). Version 1.16 still uses Python 2.7.
