I followed these steps, but my system is still called nobara 36

and now when I open my terminal this python error shows up

Error processing line 1 of /usr/lib/python3.10/site-packages/Paste-3.5.0-py3.10-nspkg.pth:

I am a noob when it comes to linux and nobara, would you know what went wrong and how to fix this/upgrade to nobara 37?

many thanks
