Accidentally installed python twice

rated 0 times [ 1] [ 0] / answers: 1 / hits: 476 / 2 Years ago, tue, december 7, 2021, 2:16:09

Ubuntu (18.0.4) newbie here. I ran

sudo apt install python3.10

in the terminal, only to discover, that python3 was already installed (next to the standard python 2.7). If I now search this most current python3.10 installation via

apt list "python3.*",

I do not find it (only some python3.8 package and older ones). I wanted to keep this installation as clean as possible, but now I do not know where this python installation went. Can I track it and remove it? Do I have multiple versions now? How do I get rid of them?

Your system should only have one version of python (2.7) and one version of python3 (3.6) installed for Ubuntu 18. If you wish to install additional versions, you can do it outside of apt by manually downloading it and installing it in its own directory.

There are also tools like pyenv that allow you to manage this. It won't affect the other installations or software that depends on those being there. Different versions can be 'activated' in the current terminal or for specific users.
