same problem at my installation after upgrading to Carbonio Release 25.9.0
the mailbox.log shows the stack trace in my logs (second block that eliwap has discovered):

I reinstall packages and notting solve
SOLUTION:
install carbonio-catalog
my case:
dnf install carbonio-catalog
pending-setups -a
su - zextras
zmcontrol restart
and works again!!
@ leorodher
zmcontrol restart
Services are now handled by systemd.
Enabled systemd targets:
- carbonio-directory-server.target
- carbonio-appserver.target
- carbonio-proxy.target
- carbonio-mta.target
Please check the documentation for further details.
Exiting.
That don't work no more in version 25.9!
apt install carbonio-catalog pending-setups -a reboot
That fixed it for me. Thank you.
zmcontrol restart

That don't work no more in version 25.9!
That was the case in 25.6 already, documentation was not up-to-date about this (I have not checked 25.9 documentation).
They switched to systemd but it's not documented.
It is somewhat documented, but leaves a lot to desire though.
https://docs.zextras.com/carbonio-ce/html/troubleshooting/services.html
Installing carbonio-catalog worked, but I still get the warning "Validation error (UnknownType@/getNotifications/notifications]) : Unknown type 'TransferredOwnership'"
this fixed that problem.
chown zextras:zextras /opt/zextras/data/tmp/nginx/client
Thanks, this worked for me on numerous nodes even without ERROR in mysql_error.log. Not sure how this got broken from an upgrade.
apt install carbonio-catalog
pending-setups -a
reboot
This resolve my problem and now all fine
Thanks!
I still get the warning "Validation error (UnknownType@/getNotifications/notifications]) : Unknown type 'TransferredOwnership'"
So do I.
admin is O now, but I also have error "Validation error (UnknownType@/getNotifications/notifications]) : Unknown type 'TransferredOwnership'" on client mail check
I think this is simulare to this thread here.
It resolved mine too - please update the documentation.
i all,
Yesterday I updated to version 4.4.3-1jammy, and after several hours of troubleshooting I discovered a critical issue with the carbonio-webui package:
Get:284 removed link jammy/main amd64 carbonio-webui amd64 4.4.3-1jammy [710 B]
The package installs successfully, but it's completely empty — no frontend files are deployed. After installation, the Jetty webapps directory remains blank:
ls -al /opt/zextras/jetty_base/webapps/zimbra/
total 8
drwxr-xr-x 2 zextras zextras 4096 Aug 25 10:59 .
drwxr-xr-x 3 zextras zextras 4096 Oct 7 11:09 ..
This breaks the entire web interface. I strongly recommend not updating until the repository is fixed or a working .deb is provided.
Can someone from Zextras confirm whether this is a packaging error or an intentional change?

Hi all,
I managed to fix the issue. If you have a backup—and I assume you do before running any updates—just restore the following folders from it:
/opt/zextras/admin /opt/zextras/web
In your working environment, rename the current folders to admin.old and web.old then copy the backup versions in their place. This restores functionality on version 25.9.0 using the old frontend. While this may cause minor issues, users can send emails and continue working. As an admin, you can unlock accounts, create new ones, etc.
Until Zextras provides a general fix, this workaround should help keep things running.
Hope someone finds it useful.
Adam
