Python3.10 guide - broken pip

[jrkessl]

Hello
While following CloudBytes.dev's Python 3.10 install guide I ran into this problem in the last step, upgrading pip. I managed to install pip using the suggested method (download get-pip.py and run it) but when I run pip it crashes; looks like somewhere someone is still trying to access pip 20.0.2 which has just been uninstalled. Who's trying to reach pip 20.0.2 and how to I tell it to use pip 22 instead?

This instance: NAME="Ubuntu"
VERSION="20.04.4 LTS (Focal Fossa)"
If I run "python3 --version" it already says 3.10.4.

I'm having the same problem. Using "pip3.10" command works, though. It's what this tutorial uses: https://www.linuxcapable.com/how-to-install-python-3-10-on-ubuntu-20-04/ .

OK. Let me take a look.

Hello.
It has been fixed. A friend suggested I try: sudo curl https://bootstrap.pypa.io/get-pip.py | sudo python3 and it fixed the problem.

pip --version now answers pip 22.0.4 from /usr/local/lib/python3.8/dist-packages/pip (python 3.8) I'm not sure it should say python 3.8 but at least it does not crash.

I had initially used sudo python3.10 get-pip.py as indicated in the tutorial and shown in my history, but guess it was just not enough.
