Python error when registering new apache domain

Help
1

I am unable to register my domain when running certbot --apache.

My domain is: dcaudio.dk

I ran this command: sudo certbot --apache -d dcaudio.dk -d www.dcaudio.dk

It produced this output:

That's really old. How did you install it?

You should use snap or pip, not the apt package that comes with Debian 10. (Or another acme client)

Okay. I had previsouly installed using sudo apt install python3-certbot-apache. I have tried again installing with snap and now have certbot 1.23.0 but see a different python error:

It's the same error. I think somewhere in your Apache directory there's a malformed filename or directory, which contains a null byte.
