So I was attempting to write a bash script to take a screen shot and send an email with the screenshot. I had found this SO answer and followed the commands. In the end I could not get mail to work for me and wanted to restart, so being a novice I decided to run

sudo apt-get remove postfix mailutils libsasl2-2 ca-certificates libsasl2-modules

And this resulted in

enter image description here

and just judging on the names of a few of the packages, I think I made a big mistake. I mean, I'm pretty sure it removed gnome-terminal even...

I am still logged on to the machine with the same terminal open and should be able to keep it open indefinitely. I assume, again from the name of the packages removed, I won't be able to boot back into the computer or open a terminal..

I know this is a really terrible question/form, but I'm not sure what else to ask or what other information to give. How do I fix this?

    Try sudo apt install ubuntu-desktop. If you really don't have a GUI Terminal application anymore, then use CTRL+ALT+F3 to get a TTY login and CTRL+ALT+F7 (CTRL+ALT+F2 in 17.10/Wayland) to return to the GUI. – user535733 Jan 23 '18 at 03:44
  • I do have the same terminal I ran the command in, but I can't open a new one. – KDecker Jan 23 '18 at 03:55
