accessibility - Upgrading and installing packages through the Cygwin command-line?

I'm a blind computer user that uses Cygwin.

The installation program isn't very accessible: upgrading, installing, and removing specific packages is quite hard to do since you have to use simulated mouse keystrokes to click and scroll.

Is there a way to either manually install/upgrade packages or install/upgrade them through the command-line?

Answer

Install apt-cyg:

lynx -source https://raw.githubusercontent.com/transcode-open/apt-cyg/master/apt-cyg > apt-cyg
install apt-cyg /bin

After that you'll be able to install say the package "lynx" including dependencies by running:

apt-cyg install lynx
