after the issue #808 i try to generate using X1 but i dont know or i dont understand what means that, i xplicid use the CN X1 but the resulting one is R3 :

process i used:

serveruno:/etc/cron.monthly# /usr/bin/dehydrated -x --cron --challenge http-01  --accept-terms --preferred-chain "ISRG Root X1"
# INFO: Using main config file /etc/dehydrated/config

 + Creating combined.pem (a combined privkey.pem + cert.pem)
 + Removing unused combined certificate file: combined-1668534558.pem
 + Done!

i get sure to changed the cert file :

cp -aLf /var/lib/dehydrated/certs/xxxxxxx.net/combined.pem /etc/ssl/certs/xxxxxxx.net.pem
chown root:www-data /etc/ssl/certs/xxxxxx.net.pem
chmod 640 /etc/ssl/certs/xxxxxx.net.pem
(test -x /etc/init.d/lighttpd && /usr/sbin/service lighttpd restart) || exit 0

then i tested the result but certfiel still marks R3, tested in edge crap so nobody can said is the browser:

R3 is the most recent signing certificate used by Let's Encrypt to sign all end-user certificates (along with E1) right now. ISRG Root X1 is the root certificate which in turn signs R3. I recommend you familiarize yourself with the certificate chains: https://letsencrypt.org/certificates/

thanks @AgentOak i was posting cos in many of my clients reported as untrusted and the only difference i found was the issuer, after a investigatino just minutes before you posted found the same info in the debian changelog.. the ISRG_Root_X1 is present in my linux, linked as lrwxrwxrwx 1 root root 51 oct 3 2020 /etc/ssl/certs/ISRG_Root_X1.pem -> /usr/share/ca-certificates/mozilla/ISRG_Root_X1.crt and R3 is the new ones , i'll close for now..
