I had a previous domain name that I don’t use anymore, and I needed to launch certbot to register a new cert for my domain. It’s been a long time that I installed it, but I already tried to apt-get remove it and reinstall it (I have it in my PPA), it did not change anything.
Thanks for the quick answer.
edit ; not sure if it’s really important, but I have two VirutalHosts on Apache.
edit 2 : I FOUND A SOLUTION o/
I just had to re-download the certbot-auto file from eff website and run it. It should have reinstalled the apache plugin, I don’t know.
Now it works normally.
