Bar at the bottom

[dmraven]

I am 100% sure. It goes from "Appearance" to "Apps"

Not sure if this helps or matters, but I did have extensions turned on and because of the bar at the bottom which suddenly popped up I had to turn them off.
Now I am trying to get that bar removed so I can turn the extensions back on.
On the log-in screen I see the following desktop options:
GNOME
GNOME Classic (selected)
GNOME on Xorg
Plasma (X11)
Ubuntu
Ubuntu on Xorg

Do you have Extension Manager (package name: gnome-shell-extension-manager) installed? If so, does it show the extension Ubuntu Dock?

[dmraven]

Yes that package is installed, but it is turned off.
Yes it does show the Ubuntu Dock Extension.

On the log-in screen I see the following desktop options:...

You might try GNOME.

I think that's what I'm using:

$ echo $XDG_CURRENT_DESKTOP
ubuntu:GNOME

Do you want the whole bar to go away?
Then toggle "window list" to off in Extensions or Extensions manager if installed.
The Extensions app should be installed.

For what it's worth I think you might want a better alternative like gnome-flashback/gnome-panel,
gnome classic is weird.
This should still work: https://help.ubuntu.com/community/GNOMESessionFlashback

In Settings I still do not have the Ubuntu Desktop option, but the bar at the bottom of the screen is gone now...

Changing from GNOME-Classic to GNOME seems to have resolved the issue for now.
Thanks everyone!
I am grateful for all the help and advice!
