I have installed SageMath in Ubuntu 18.04. However I cannot launch sagemath from the applications (actually it is not even there) neither can I launch from command line.

(base) dimitris@dimitris-Inspiron-5567:~$ sudo apt-get install sagemath

(base) dimitris@dimitris-Inspiron-5567:~$ sagemath
sagemath: command not found

When I type

apt list --installed

I see sagemath in the list of applications installed.

I used to use sagemath in 16.04 without problem. Is there any problem with 18.04? Am I missing something? Thank you very much in advance.

The main Sage executable is named sage, it came from sagemath-common package.
And this package was installed as dependency of sagemath package.

So you need to give single command:

sage
