Zimbra renewal - Problems with R3

I don't think that's the file I asked for...

none-the-less, try:
su - zimbra -c "/opt/zimbra/bin/zmcertmgr deploycrt comm cert.pem chain.pem
[again, add path as needed]

Here is the output of the deploycert:

Thank you!

did that get done?

No, I had to stop because the built-in apt update did not update the version and in Ubuntu 16.04 if I install from the source there may be incompatibilities with the system maintenance updates. So I need to investigate further before breaking anything else. Is the OpenSSL version a showstopper for the certificates deployment?

That depends, what version of OpenSSL do you have (again)?

where does it go wrong?
step #1 sudo apt update
step #2 sudo apt install libgnutls-openssl27 libgnutls30
step #3 sudo apt install ca-certificates

openssl is v.1.0.2g

Then you need to apply steps #2 and #3.

Doesn't really go wrong, it is that the new version is not available in the repo so the only option is to install it from the source, which from what I see also updates/overwrites libs that cause conflicts with regular system maintenance updates...

Which?

Thank you, I think Workaround #1 is the only viable option....

If I apply Workaround 1 and 'remove' the DST cert from the store, do I need to do anything else in Zimbra (besides restarting it)?
If I manage to update openssl, do I need to do anything else in Zimbra (besides restarting it)?
Sorry for asking what seem trivial questions.

I think you might have to redeploy the cert.
But try the reboot only thing first - it might work.

Did you manage to apply workaround 1?
Can you post some update ao the solution you found?
I have the same problem on a production server and i don't want to mess up something.

Hi @norbinus welcome to the LE community forum :slight_smile:

Please include more details in your post.
As is, only the person that matches your "I have the same problem" would understand what your problem actually is (and those that have recently read through the all 35 posts here).
Many people come to this forum and most are willing to help - help them (all) help you.
It might seem totally redundant but it really actually isn't - think SEO.

In my limited understanding, the problem relates to the expiration of the DST Root CA X3. Following the instructions found here, I blacklisted X3 and tried to verify the newly generated certs, but I got the following error:

[zimbra@mail letsencrypt]$ /opt/zimbra/bin/zmcertmgr verifycrt comm privkey.pem cert.pem chain.pem
** Verifying 'cert.pem' against 'privkey.pem'
Certificate 'cert.pem' and private key 'privkey.pem' match.
** Verifying 'cert.pem' against 'chain.pem'
ERROR: Unable to validate certificate chain: cert.pem: C = US, O = Internet Security Research Group, CN = ISRG Root X1
error 2 at 2 depth lookup:unable to get issuer certificate

I also use an old version of Open SSL: OpenSSL 1.0.2l

I have this working using the following for the chain.pem:

Be aware that chain.pem (and fullchain.pem) will be replaced on their next renewal.
If you want to continue using that shorter/alternate trust path chain, you must instruct the ACME client to do so. Which can be done with the added parameter:
--preferred-chain "ISRG Root X1"
