This really helped. I can find an Electrum icon within the Ubuntu software. Now, I have one more question, what happens if I remove the desktop icon [ electrum.desktop ]? When I click it, it opens snippets.
I think the Icon from the desktop on Linux is just a shortcut or a link to open the Electrum. So even you delete/remove them the wallet still installed on your device.
What exactly do you want to achieve on Electrum in your Linux device?
What do you mean about snippets? Do you mean if you put the mouse cursor into the Electrum icon then it shows something like a name, date, and size?
If ever you want to get your icon back you need to create a shortcut icon again on the desktop you can follow this below,
touch ~/Desktop/electrum.desktop
nano ~/Desktop/electrum.desktop
# Paste the following code inside the editor, save and close.
[Desktop Entry]
Name=Electrum
Comment=Lightweight Bitcoin Wallet.
GenericName=Bitcoin Wallet.
Exec=/usr/local/bin/electrum
Icon=/opt/electrum/electrum-icon.png
Type=Application
# Download icon for the shortcut
cd /opt/
sudo mkdir -p electrum
cd electrum
sudo wget http://icons.iconarchive.com/icons/alecive/flatwoken/256/Apps-Electrum-icon.png
sudo mv Apps-Electrum-icon.png electrum-icon.png
# Change shortcut permission
chmod +x ~/Desktop/electrum.desktop
# Add shortcut to launcher
sudo cp ~/Desktop/electrum.desktop /usr/share/applications/
