For anyone getting the error: 'Unable to locate package python-openssl' - you can run the following command in your terminal:

sudo apt install python3-openssl

Thank you for this excellent guide and thank you to everyone who contributed to Pyenv. I just overcame a problem with a set-up script that is really picky about the python version used. Naturally, I encountered this problem while I'm in a hurry, so Pyenv really saved my bacon.

To be honest first time dealing with Linux one the things that frustrated me was the installation of python globally that I almost went back to windows but this tutorial did ti right you deserve more recognition

My system's apt is not able to find python-openssl ('Unable to locate package python-openssl').
I went ahead and skipped the package, would there be problems related to this?

I'm getting an error in ubuntu 22 "E: Unable to locate package python-openssl"

I have already downloaded python3-openssl but its not working.

when I use python -V to check the version after setting the global or local version to the one I installed it still shows version 2.7.17

Thanks for the video ! Btw you can just ‘source ~/.bashrc’ instead of closing and reopening a terminal.
