Update your client software to continue using let's encrypt

Help
1

from the error it sounds like I have to update my certbot client, but I just want to make sure there is no other part to this I have to do.

because before doing anything, I upgraded

$ sudo apt-get update
$ sudo apt-get install --only-upgrade certbot

and got the message:

certbot is already the newest version (0.31.0-1+ubuntu16.04.1+certbot+1).
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.

Am I really finished without doing anything?

Could you show the error message and where/how you got it?

Also, can you show?:
apt list --upgradeable

the only error I got was the above error, and when I list upgradables:

$ apt list --upgradeable -a

my certbot does not appear to be the latest version. Is that the problem? I can't upgrade it.

Too soon to tell, please show where/how you get the error message.

The error comes from the following command:

$ sudo apt-get install --only-upgrade certbot

I’m confused…
Can you show a screenshot?

The title of this topic is:
“Update your client software to continue using let’s encrypt”

Where did you receive that message?

you may need to check your configuration files for each domain you are trying to renew.

the configuration file may have a setting which points to a renewal server which is using version 01

change it to version 02
