Public bug reported:

cannot force a local upgrade to cffi v2.0... i probably have to dig
deeper into replacing the old v1.

also, i cannot use a virtual environment - certbot requires direct system acces when renewing certificates. 
 

#python3 -m pip install --upgrade acme certbot certbot-dns-cloudflare

results in an error message:

the currently installed cffi is from the ubuntu packages distributed with Ubuntu Noble LTS (24.04.3 currently)

since cffi in ubuntu is imported from Debian, please try impoting the v2 cffi too
