Restore snap, and some time later try the upgrade again, downgrading openjdk/core/ldap/jetty immediately after, then reboot and Zimbra came up fine.

dnf -y downgrade zimbra-openjdk-13.0.1-1zimbra8.8b1.el8.x86_64
dnf -y downgrade zimbra-jetty-distribution-9.4.18.v20190429-2.r8.x86_64

I actually had to do this last upgrade as well because that failed, but forgot the detail of what I had to do to fix it because just fixing it. Thanks for posting. This time I'm writing it down in Confluence for 2024 it would seem...

dnf downgrade zimbra-openjdk-13.0.1-1zimbra8.8b1.el8.x86_64

This downgrades also 3.0.11-1zimbra8.8b1.el8 and 2.0.5-1zimbra8.8b1.el8 you should agree with it. 

And after that you need to downgrade one more component:

dnf downgrade zimbra-jetty-distribution-9.4.18.v20190429-2.r8.x86_64

After downgrades zimbra will start up.

Can you help solve it? Because users can not change passwords by themselves.

Many tahaks in advance. 

I'm too tired for doing this ...

This is a solution on Zimbra Forum post above ...

Can someone give us a way of doing this on Ubuntu 18.04 ??

THIS STEPS ARE FOR CENTOS 7!

Remove:
zimbra-core-components.x86_64 0:3.0.12-1zimbra8.8b1.el7
zimbra-jetty-distribution.x86_64 0:9.4.46.v20220331-2.r7
zimbra-ldap-components.x86_64 0:2.0.6-1zimbra8.8b1.el7
zimbra-openjdk.x86_64 0:17.0.2-1zimbra8.8b1.el7

Install:
zimbra-core-components.x86_64 0:3.0.11-1zimbra8.8b1.el7
zimbra-jetty-distribution.x86_64 0:9.4.18.v20190429-2.r7
zimbra-ldap-components.x86_64 0:2.0.5-1zimbra8.8b1.el7
zimbra-openjdk.x86_64 0:13.0.1-1zimbra8.8b1.el7

If I try to remove one it gives a lot of dependencies also to be removed, and maybe someone more 'fresh mind' can solve this for us, also we need to be able to fetch the packages from some old repo, since the ones are the referenced as to be removed.

Hi everyone, just to build on this reply-

I am running Centos7 and was able to restore functionality by running the following, thank you @jasgg_it for doing the leg work on the packages.  I had to do ldap before core components in order to avoid dependency issues.

yum downgrade zimbra-ldap-components.x86_64 0:2.0.5-1zimbra8.8b1.el7

yum downgrade zimbra-core-components.x86_64 0:3.0.11-1zimbra8.8b1.el7

yum downgrade zimbra-jetty-distribution.x86_64 0:9.4.18.v20190429-2.r7

yum downgrade zimbra-openjdk.x86_64 0:13.0.1-1zimbra8.8b1.el7

This seems to have me up and running again.

From a comment on this blog specifying Centos it looks like "yes" Centos is affected as well. (but no version is mentioned)

regards. (matane)

I'm using CentOS 8 Stream and two days ago I tried a clean install and got exactly the same issue.
