I did a fresh installation of Carbonio today. After a lot of trial and error, I identified the main issue.

Key Issue

The following command:

PGPASSWORD=$DB_ADM_PWD carbonio-message-dispatcher-migration carbonio_adm 127.0.0.1

is related to the migration of the old chat UI. It updates the version column in the database that Carbonio uses to track updates.

⚠️ Important:
The migration services — ws, tasks, docs, message-dispatcher — do not actually perform any changes on PostgreSQL. Everything else seems up-to-date because the system reads the version column and assumes the updates were applied.

Verifying PostgreSQL Users and Databases

Connect to your PostgreSQL instance:

psql -h 127.0.0.1 -U carbonio_adm

Check users:

\du

Check databases:

\l

Verify the users and tables for each database:

• carbonio-ws-collaboration-db

• carbonio-tasks-db

• carbonio-message-dispatcher-db

• carbonio-docs-db

Each service has its own user and database, following the pattern:

⚠️ Note: If anything is missing, it indicates a problem. In my case, it was a fresh install — I deleted everything and restarted the installation.

Recommended workflow (in a fresh install; adapt for previous installations):

1. Run all pending setups except carbonio-message-dispatcher.

2. After these, populate the databases:

PGPASSWORD=$DB_ADM_PWD carbonio-message-dispatcher-db-bootstrap carbonio_adm 127.0.0.1
PGPASSWORD=$DB_ADM_PWD carbonio-docs-connector-db-bootstrap carbonio_adm 127.0.0.1
PGPASSWORD=$DB_ADM_PWD carbonio-tasks-db-bootstrap carbonio_adm 127.0.0.1
PGPASSWORD=$DB_ADM_PWD carbonio-ws-collaboration-db-bootstrap carbonio_adm 127.0.0.1

3. After these runs, execute the PostgreSQL verification commands (\du and \l) to ensure all users and databases exist.

4. Then return to pending setups and run carbonio-message-dispatcher.

5. Finally, run the infamous last migration:

PGPASSWORD=$DB_ADM_PWD carbonio-message-dispatcher-migration carbonio_adm 127.0.0.1

⚠️ Warning: Running the last migration too early will break PostgreSQL. Always follow this sequence.

Completely shutdown Carbonio and Start again.

Chat not working as per above message.

Stop and start the following services:

carbonio-message-dispatcher.service
carbonio-ws-collaboration.service
carbonio-tasks.service

Not so sure but, I think stop/start all three services made it work.

Will I have to do restart of all three services again and again? Don't know, time will tell.

PS. That is a fresh installation of 25.3.1

/var/log/carbonio/ws-collaboration# ws-collaboration.log

Same error as user: hidigoudi

I am on Carbonio CE 25.3.1

Unexpected MUCLightAdminMutation resolver crash

Please help to resolve it.

I have a similar issue with chat and video server features. Chat isn't working. When I try to send a message to someone the message stays as "Pending" state and I got this error in logs :

25-03-2025 15:56:38.126 ERROR c.z.c.c.c.logging.ChatsLogger  : An error occurred on /rooms 
 at com.zextras.carbonio.chats.core.infrastructure.messaging.impl.xmpp.MessageDispatcherMongooseImpl.createRoom  
 Error while creating a room: [{"path":,"message":"Unexpected MUCLightAdminMutation resolver crash","extensions":{"code":"resolver_crash"}}]

Same issue when I try to create a virtual room.

When I reboot the server, I also have a service error "carbonio.service" in failed state. I need to restart the service to make it working.

:~# su - zextras -c "zmcontrol -v"
Carbonio Release 25.3.0

Could you please help me ?

Thanks.

I executed:

su - zextras -c "carbonio prov mc default carbonioFeatureWscEnabled TRUE"

I restarted the services:

su - zextras -c 'zmcontrol restart'
systemctl restart carbonio-tasks
systemctl restart carbonio-message-broker
systemctl restart carbonio-message-dispatcher
systemctl restart carbonio-ws-collaboration
systemctl restart carbonio-videoserver

and I already have the Chat working without any problem, my question is the following since I did not know this command, su - zextras -c "carbonio prov mc default carbonioFeatureWscEnabled TRUE" is something new in this version?

I ask because as I mentioned before, in my Carbonio version 24 this also returns FALSE and I still have the Chat working.

@sharif Thanks for the help

This is the result of the previous command:

# name default
carbonioFeatureWscEnabled: FALSE

I also have a Carbonio CE 24.x with the Chat working without problems, the command shows the same result.

The problem is that it does not appear in the web client

Could you please check followings:

su - zextras -c "carbonio prov gc default carbonioFeatureWscEnabled"

curl -v http://127.78.0.4:10000/health | jq

I can see that everything is correct and enabled, but it doesn't appear in Webmail.

I performed a fresh, clean install of 25.3, and the result is the same: there's no Chat.
I noticed that when I run:

systemctl list-units "carbonio*"

I see that carbonio.service isn't running:

carbonio.service loaded failed failed LSB: Carbonio Services

But all services are working correctly: mail, tasks, files.
Any help? Is this something general?
