I am trying to install Python 3.11. To add the PPA, I do the following steps:
first : sudo add-apt-repository ppa:deadsnakes/ppa
secound : sudo apt update
I get this error:
Err:3 http://ppa.launchpad.net/deadsnakes/ppa/ubuntu focal InRelease 403 Forbidden
I restore default repositories like this link but still problem.
My OS : Ubuntu 20.04.5 LTS
