 This reveals that you should consider studying some guide to using /and
administrating/ a Linux system -- though to simplify things: focus on
Debian based distributions -- you are probably not running a red-hat
distribution which uses a whole different package manager...

 Possibly because they consider it a specialized administration tool,
and hence don't list it in the common user applications. (I don't have time
to connect my RPi-3 to the upstairs TV in order to get to the desktop -- I
normally SSH in from my Windows machine and use the resulting command
line).

 If you don't want to take the time to study tutorials for each of the
major ones, that is just as reasonable a choice as any other.

 I'd likely base it upon what documentation I could find and study, map
the widget set to what I feel I need (things like an expandable tree
display may not be part of a framework and would require the user to write
there own "macro widget" and all event handling for it), consider how
difficult it is to do background processing (work routine that only runs
when the rest of the event loop is empty -- and has to be written to only
do a few steps with a saved environment before returning to check for
events... vs being able to spawn a thread with a means for the thread to
communication back to the event loop as needed; pretty much all of the
frameworks are not happy if a thread attempts to process events in parallel
with the running "app" object).


>I wish I could.  I just tried to "sudo apt-get --download-only install

Didn't you say you don't know what a package manager is?

"apt" is the Debian-based command line package manager. (and graphical ones
tend to have "apt" somewhere in their name -- but you may have to first
install them )

 And what else did the command display? Problems with repositories?
Network connection glitch?

 I've never used the "download-only" option so don't know what type of
effects that could have.

 Also, did you do an "apt-get update" first to make sure the package
list is up-to-date?
