Installing python: who is deadsnakes and why should I trust them?
I want to install Python 3.9 on my Ubuntu 20.04, and all tutorials I can find include a step as follows:
sudo add-apt-repository ppa:deadsnakes/ppaI am concerned about security. I've looked into this question: Are PPAs safe to add to my system and what are some "red flags" to watch out for?
According to the answers, some of the main points to consider are:
- Who made the PPA
- Someone named deadsnakes, apparently, but what can I conclude from this?
- How many users have used the PPA
- Where to get this information? Someone asked this in a comment 9 years ago but it wasn't responded.
Attempts to search the internet for deadsnakes only brought me into tutorials on how to install Python, which is where I started...
Thanks!

Note: Please don't change the default version of python3. You may end up destroying Ubuntu. Instead, run python3.9 with the command python3.9.
Also, you can install python 3.9.5 in Ubuntu 20.04 even without the deadsnake PPA with the commands
sudo add-apt-repository universe
sudo apt update
sudo apt install python3.9Now let's answer your questions.
Someone named deadsnakes
