Ubuntu 18: Lost icons in top right of Classic View [SOLVED]

ASUSTeK P6-P5G41E running Ubuntu 18.04 in gnome-flashback

I thought I was removing just one icon from the top right panel but they all disappeared!
I’ve done this before (sorry!) but can’t remember how to recover them, and my web search wasn’t helpful.

I would be grateful for advice.

[EDIT] Tried dconf reset -f /org/gnome/gnome-panel/ without success.

[EDIT 2] Tried:
sudo apt-get update
killall gnome-panel
sudo apt-get install --reinstall gnome-panel gnome-applets
sudo apt-get -f install

…after this, ALL the top panels disappeared but a reboot restored them. Success!

Great stuff Keith :slight_smile:

Thank you Mark. That’s good for my ego but I can’t claim any skill here as I ought to have acknowledged the solution at [ubuntu] Desktop (gnome) missing icons and applets.
Just shows that if one keeps searching for long enough the answers are usually out there somewhere. Or more usually, here.

No matter where it comes from, understanding the problem and how to find a/the solution is a skill.
