Failed building wheel for annoy (Ubuntu 20.04)

Hi,
Annoy package installation fails. Where am I doing wrong? I would be glad if you help.
My computer using Ubuntu 20.04.3 LTS ( Python 3.8.10, gcc 9.3.0, g++ is not installed )

~$ pip install annoy

I'm also running into a problem installing g++. This could be the source of the problem. I would be glad if you share your thoughts on this.

~$ sudo apt install g++

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 g++ : Depends: g++-9 (>= 9.3.0-3~) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

These issues seem unrelated to Annoy? Looks like you're having issue installing GCC
