What package are you installing?
Not all packages will create an entry in the menu.
Sometimes you have to search all the menus to find it.
Installing something on one OS does not install it on any others.
IMO synaptic is a much better package manager:
Code: Select all
sudo apt update
sudo apt install synaptic
The start icon will be in Preferences.
Unless specified otherwise my response is based on the latest and fully updated Raspbian Stretch w/ Desktop OS.
