Let's Encrypt new chain of trust is now the following:
- ISRG Root X1: C = US, O = Internet Security Research Group, CN = ISRG Root X1
  (was previsouly also cross signed by DST Root CA X3: O = Digital Signature Trust Co., CN = DST Root CA X3)
- R3: C = US, O = Let's Encrypt, CN = R3
- your server cert

You mention that the cross-signed root certificate was removed with ipa-cacert-manage, but did you also run ipa-certupdate before trying ipa-server-certinstall? This step is mandatory in order to update the NSS databases, as specified in the man page ipa-cacert-manage(1).

Hi! I've been using FreeIPA (installed without CA --no-pkinit) with letsencrypt certificate. Whenever the certificate gets renewed I install it with
ipa-server-certinstall for both the LDAP and web server and that has been working just fine. Recently the root certificate (DST Root CA X3)
expired as mentioned here https://letsencrypt.org/docs/dst-root-ca-x3-expiration-september-2021/

Now when I try to install the new certificate I get this error:
CA certificate CN=DST Root CA X3,O=Digital Signature Trust Co. in /etc/letsencrypt/live/XXX/cert.pem, /etc/letsencrypt/live/XXX/privkey.pem is not valid: certutil: certificate is invalid: The certificate issuer's certificate has expired. Check your system date and time.

The ipa-server-certinstall command failed.
I don't understand this error message at all since the `cert.pem` file does not contain any reference to the X3 CA, so I suppose it must come from somewhere else. Does someone have an idea how to fix this?

I've already removed the root certificate with ipa-cacert-manage and added the self-signed X1 root cert, yet the same error message above keeps showing up.
