Description: automatically configure HTTPS using Let's Encrypt
 The objective of Certbot, Let's Encrypt, and the ACME (Automated
 Certificate Management Environment) protocol is to make it possible
 to set up an HTTPS server and have it automatically obtain a
 browser-trusted certificate, without any human intervention. This is
 accomplished by running a certificate management agent on the web
 server.
 .
 This agent is used to:
 .
   - Automatically prove to the Let's Encrypt CA that you control the website
   - Obtain a browser-trusted certificate and set it up on your web server
   - Keep track of when your certificate is going to expire, and renew it
   - Help you revoke the certificate if that ever becomes necessary.
 .
 This package contains the main application, including the standalone
 and the manual authenticators.

root@sd-118150:~# apt policy certbot
E: L'opération policy n'est pas valable

Thanks

oh well, it was probably apt-cache policy certbot

I'm beginning to think that the only way is indeed to dpkg -r certbot and python-certbot if apt refuse to do it.
All this stuff is a bit old since certbot is not packaged for jessie since a looong time (2 years?). Also possibly your local apt database is not in a good state since jessie-backports is now dead.

Hello @gpatel-fr, thanks for your reply.
So I will try dpkg -r certbot and python-certbot. I willbe in holidays a few days, so I prefer to test it when I come back. I will let you know.
An other confusion for me is that the cron name is "cerbot ", so cerbot+space. Could it be the explanation ? … Have a nice day
