How to intall Pip, Venv And upgrade Python on Linode?

Hi,
I want to run some python scripts from my Linode, and for that, I need to upgrade the python version, install python3.10-venv and python3.10-pip, but when I try to, for example, install python3.9-pip I get a lot of errors as shown below. What can I do to solve this problem, and install these components?

root@localhost:~# apt install python3-pip --fix-missing
