If I press the calculator button in my keyboard, the gnome calculator app doesn't appear. I have double checked that the shortcut is ok in the settings app keyboard bindings config pane.

I found that installing the calculator app via apt instead of snap (the default in 18.04) fixed this issue:

sudo snap remove gnome-calculator
sudo apt install gnome-calculator

This has the added benefit of making the calculator launch instantaneously again.

The cause of the problem is a bug in the gnome-settings-daemon package, which has been fixed in Ubuntu 18.10 and above. The workaround above remains necessary in 18.04, however.

    Great! It also solved the complete transparency window by having enabled Communitheme! – razor7 May 7 '18 at 11:50

    How could they possible break the Calculator ? Of all things that may be broken this one should always work on any OS, no matter what... Imagine being a new person to (Ubuntu) Linux and finding that your calculator simply does not work with no error. – Flatron Sep 10 '18 at 7:44
  • @Flatron: there are even more basic things that they broke in Ubuntu 18. – Dan Dascalescu Jan 2 '19 at 6:43

    Working like a charm, with my Micorsoft keyboard! – Lizozom Feb 16 '19 at 11:33

You can remove the default shortcut for "Launch Calculator"...

Remove default Calculator shortcut

and instead add a custom shortcut to run gnome-calculator, and assign the Calculator key to it:

Custom Calculator shortcut

  • In my case shortcut button doesn't respond when I press calculator button. This doesn't also respond when I try to bind already defined shortcut – Herrgott Sep 3 '19 at 9:31
