With
ipa-server-certinstall -w -d fullchain.pem privkey.pem
I've got following error
The full certificate chain is not present in fullchain.pem, privkey.pem
I instead had success with
ipa-server-certinstall -w -d cert.pem privkey.pem
I'm not sure if my fullchain.pem is broken or if there have been recent changes in certbot.
