Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. crt.sh | example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.
My domain is:localevents.online
I ran this command:sudo certbot renew
It produced this output:Traceback (most recent call last):

The version of my client is (e.g. output of certbot --version
or certbot-auto --version

It all starts with autorenew doesn't work. then found out certbot stops working.
By reinstall snapd on ubuntu20, then sudo snap install --classic certbot. certbot is back.
Now it's ok.
