The mythexport package should be fine on any 16.04 Ubuntu based
system.  It is a bit of pain installing using dpkg as the dependencies
are not automatically installed, as you found out.  But what you have
done is correct - the dependencies need to be installed using apt, so
their dependencies will also be installed.  On other distros, the
package files would need to be extracted and put where that distro
wants them, and integrated into Apache, and any dependencies installed
manually.

The mythimport program is different - it is just a single file Python
program.  It needs MythTV and Python 2 and the MythTV Python bindings,
but will tell you what else it needs if it does not find it, and does
not need installing as such - it can be run from anywhere.  I normally
put a copy of it on the media I am using to transport the exported
files and often run it from there.

I have considered creating a mythexport Python program that works like
mythimport does - just a single file Python program.  It would be
given some SQL to use to look up the database and identify recordings
to be exported, then do the export process when the user said it had
found the right recordings.  That would make it much easier to use on
non-Ubuntu systems.  But the GUI would not be available, so it would
not be as easy to use.  If anyone wants such a mythexport program,
please let me know.  It should not be too difficult to write.
