I reinstalled the Ubuntu 18.04 server
I did not save the certificates before reinstalling
so
now I don’t have any certificate on the server in the directory /etc/letsencrypt/
I want to issue another certificate
the existing ones are for Apache2, and now I use nginx
I used the command #certbot --nginx

If you've deleted the server instances (or deleted the certificate files from them), the private keys are destroyed--you had the only copy of them. The public keys are, as the name suggests, public. They are immutably logged and cannot be changed or removed. But they can't be used without the private keys, which you've already destroyed.
