Uninstall a package completely(python)

coolx · 05-02-2019, 05:13 AM

Hi,
I want to uninstall python 2.7 on Redhat server but I don't now how to do it.

I run "yum list installed ""python"" command and it gives lots of package name. I uploaded the screenshot.

Which one is the kinda "root one", how can I know that?

And how can I uninstall python?

If you look at "man yum" this manual page will tell you what you need to type after "yum", being the word "erase".

You should also be paying for RHEL or use CentOS, which is almost identical.

EDIT: Forgot to say, yum itself is a python program, so it wouldn't be advisable to remove python 2.7 from your system. Why do you want to remove it?

Out of interest, why are you contemplating removing Python 2.7?

Have you confirmed that no software at all on your machine uses it?

Python 2.7 comes from official CentOS repo's, therefore it would be used by yum. So if they did remove it, then yum would be pretty well screwed. That's why I mentioned the fact yum is a python program.

It depends on which version of RHEL the OP is running, but RHEL 8 uses Platform-Python for yum and other Python system tools:

If you look at their screenshot you'll notice "anaconda", which means Python is coming from the official RHEL repo's. I can't see any package there named "platform-python". To be clear: I'm not disputing what you're saying, but I somehow doubt they are using RHEL 8 based on their screenshot - but I could be wrong about that too.

As RHEL 8 is still in BETA test phase, not released yet, I would be surprised too: you have to register as an offcial beta-tester to download it.
The latest RHEL release is 7.6

Cheers. I reckon I'll stick to commenting on Debian-derived distros.

Thanks guys,
Actually there is no special reason for uninstalling python 2,7, just trying to understand how package logic works.
