I have not upgraded to version 5 yet as I have spent a lot of time customizing what I have.

I search Lite software in Control panel and Synaptic was not there.  I did a file search for Synaptic and it was not there.

I cannot use CLI to install it due to same stated reason.

If you search for Synaptic you won't find it, Linux is case sensitive and the pkg is currently called synaptic  all lowercase. Open a terminal and type

Code:

apt policy synaptic

you should get something similar to this

Code:

synaptic:
Installed: (none)
Canditate: some_number_version
version table:
some_details_on_pkg

then install it by typing

Code:

sudo apt-get install synaptic

hit enter, type your passwd when asked and hit enter again, wait for synaptic to be installed, once it is, click on menu and start typing synap ... it should appear, click on it or hit enter to lauch it, once it's started you can browse categories or use the search fuction to find a pkg.

Apt offers many options to search and find pkgs which are available in its database, a very useful one is:

Code:

apt-cache

For example you could

Code:

apt-cache showpkg synaptic

which will show some details about synaptic pkg such as dependencies. Another useful apt's command is

Code:

apt show pkg_name

which as its name suggests, shows details of said pkg. The terminal is a very powerful tool and any Linux user will profit greatly  by learning how to use it at this very basic level. It might look a bit challenging but once you grasps the basics you'll start to feel more comfortable at using it. Read this post for more info
