Missing Calculator icon in Ubuntu 18.04 with vanilla GNOME

I have installed vanilla GNOME shell in Ubuntu 18.04 and the icon of Calculator is missing.

How can I fix this?

Solution 1:

The pre-installed (GNOME) Calculator application on Ubuntu 18.04 is a snap application, it doesn't have .desktop launcher(s) for the application at traditional place(s), e.g. /usr/share/applications/. Check the /var/lib/snapd/desktop/applications/ directory instead.

Alternatively, you may consider creating a custom .desktop launcher for the application by hand. To do so, follow the steps below.

1. Create a new file, say calculator.desktop in your ~/.local/share/applications/ directory. You can do that by running the following in Terminal

   touch ~/.local/share/applications/calculator.desktop
   

2. Open this file with a text-editor, for example by running

   gedit ~/.local/share/applications/calculator.desktop
   

3. Add the following lines to this file and save the file.

   [Desktop Entry]
   Name=Calculator
   Comment=Perform arithmetic, scientific or financial calculations
   Exec=/snap/bin/gnome-calculator
   Type=Application
   Icon=accessories-calculator
   Terminal=false
   NoDisplay=false
   

You may also remove the snap version by running

snap remove gnome-calculator

and install the traditional apt versions by running

sudo apt install gnome-calculator
