Raspberry Pi Forums

I did the install:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install claws-mail
I cannot find the program in the desktop menu

Type in a terminal if that works then it is installed ok. Sometimes i find that a GUI reboot updates the start menu so that is worth a try. If it is installed ok but a GUI reboot doesn't work search for adding items to start menu or desktop whichever you prefer and go from there
