Install Python3.10 on Ubuntu 23.04
I’ve tried to install python3.10 alongside with native python3.11, on Ubuntu 23.04, but looks like it’s not available.
mika@system:~$ sudo apt update && sudo apt install python3.10

I’ve tried to use deadsnakes, but they don’t have the Release file for current Ubuntu version. Executing sudo add-apt-repository ppa:deadsnakes/ppa confirms that.
Is it possible to install python3.10 on Ubuntu 23.04?
One way to do this is to include the repos from an old version. This may include more packages than you would like, but I’ve found it works. Generally safe, doesn’t bother other things, and fairly benign.
sudo add-apt-repository -y -s deb http://security.ubuntu.com/ubuntu jammy main universe
Then your system will see older software options, including from jammy distro.
try this instead of deadsnakes:
sudo add-apt-repository ppa:savoury1/python
sudo apt update
sudo apt-get install python3.10
