ImportError: cannot import name 'decodestring' from 'base64' (/usr/lib64/python3.9/base64.py)

Hey, can you help me to fix bug that says

ImportError: cannot import name ‘decodestring’ from ‘base64’ (/usr/lib64/python3.9/base64.py)

when I’m trying to install app?

You’ll need to be a bit more specific. What application are you trying to install? What command did you run to receive that error? What distribution are you running on?
