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

How can I fix this?

Best Answer

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
