Arcane process of obtaining cert from acme-client

[savchenko]

After hours of wrangling around this error:

acme-client: transfer buffer: [{ "type": "urn:acme:error:unauthorized", "detail": "No registration exists matching provided key", "status": 403 }] (120 bytes)

I have found https://www.mail-archive.com/[email protected]/msg158174.html which provided sequence of actions that allowed to obtain cert. Not sure why requested-delete-request again was necessary, but it worked.

On the sidenote, first two snippets of code provided at Install :: Let's encrypt section don't quite work:

sed -i -e "s|^$(echo -e "\t")tls|$(echo -e "\t")#tls|" \
	-e "/# (!) TLS/ s|listen on \$IP tls port https|listen on ::1 port http|" \
	/etc/httpd.conf

returns bash: !: event not found. Not a regexp guru, but it seems like ! should be escaped.

The acme-client error, in the mailing list message, was related to "agreement url". Perhaps the key format also changed at that time, I don't recall.

Remove deprecated agreement url.

rm old keys (from <=6.2 era) before running the client - remove file /etc/acme/letsencrypt-privkey.pem
