How to install python3.10 virtual environment when python3.10-venv has no installation candidate? [closed]

I had just upgraded to Ubuntu 22.04.1 LTS, which comes preinstalled with python3.10. I tried creating a virtual environment but it was unsuccessful. Trying to install the virtual env package gets an error E: Package 'python3-venv' has no installation candidate

python3 -m venv newpy310The virtual environment was not created successfully because ensurepip is notavailable.  On Debian/Ubuntu systems, you need to install the python3-venvpackage using the following command.    apt install python3.10-venvYou may need to use sudo with that command.  After installing the python3-venvpackage, recreate your virtual environment.Failing command: ['/home/user/Desktop/pyenvs/newpy310/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']

Following which i used sudo apt install python3.10-venv, and was returned with

sudo apt install python3.10-venvReading package lists... DoneBuilding dependency tree... DoneReading state information... DonePackage python3.10-venv is not available, but is referred to by another package.This may mean that the package is missing, has been obsoleted, oris only available from another sourceE: Package 'python3.10-venv' has no installation candidate

Something similar can be encountered if I used sudo apt install python3.10-virtualenv

sudo apt-get install python3.10-virtualenvReading package lists... DoneBuilding dependency tree... DoneReading state information... DoneE: Unable to locate package python3.10-virtualenvE: Couldn't find any package by glob 'python3.10-virtualenv'E: Couldn't find any package by regex 'python3.10-virtualenv'

My sudo apt-get update also looks suspicious, but i am not entirely sure if it is the culprit

I also have already added the deadsnakes ppa repos. I noticed some other questions were for python 3.6 or 3.8, which had worked in the past when i was using python 3.6 and 3.8 respectively. However, the methods described within does not work for my current setup with Ubuntu 22.04 and python3.10.

1. python3.8-venv not working with python3.8 -m venv env
2. python3.8-venv is no longer working after Pop OS upgraded to 21.04
3. Trouble Installing Python3.6 Virtual Environment on Ubuntu 22.04

These are the other links that I have consulted but did not work for me. I have also tried reinstalling python3.10 itself.
