Carbonio-CE; RHEL 8 to Ubuntu 22 or 24

aurfalien — Sat, 19 Sep 2026 17:36:17 +0000

I've already performed a considerable amount of work migrating for Zimbra 10 FOSS to Carbonio-CE. I'm on RHEL 8 and would like to migrate to Ubuntu. Mt thoughts on migrating are;

1) Install a clean and matching version (same as what's on my RHEL) of Carbonio-CE on Ubuntu, either Ubuntu 22 or 24 but probably 22 as it might be more battle hardened. I'm open to thoughts on this.

2) Stop the various Zextras/Carbonio-CE services.

3) Rename the clean install; /opt/zextras to /opt/zextras.ORG as an example.

4) Rsync /opt/zextras from the RHEL server over to the Ubuntu server.

5) Rerun the installer on Ubuntu.

Is my procedure flawed or missing anything?

ARC implementation

Hi All,

While searching the forum for ARC implementation, I saw that there was a survey back in 2024 but no other relevant information about that topic.

My question: is there a plan for Carbonio to implement this at all ?

Many thanks & kind regards,

Manuel

The delegated administrator cannot set an email signature from the user record.

How to grant a user delegated administrator permissions to set email signatures from the user profile; I have tried the following:

Allow editing the user's plain-text signature
# su - zextras -c "carbonio prov grantRight domain domain_name usr user@domain set.account.zimbraPrefMailSignature"

Allow editing the user's rich-text signature
# su - zextras -c "carbonio prov grantRight domain domain_name usr user@domain set.account.zimbraPrefMailSignatureHTML"

However, it doesn't allow saving the signature or viewing the created signatures in the list; clicking the "Accept" button does nothing—it's as if the system were frozen. Please help me with this.

Problem: The meeting you are looking for does not exist - Carbonio Release 26.6.2 (CE)

Dear All

The requirements I'm using are:
Ubuntu 24.04
Carbonio Release 26.6.2 (CE)

Is this a bug or a configuration error on my part? I'm getting the error "The meeting you are looking for does not exist" when someone else joins the meeting as a guest. I've tried various methods and I'm frustrated because they haven't solved my problem. I really need your help :(

What I've done:
1. systemctl restart carbonio-message-broker (status active)
systemctl restart carbonio-message-dispatcher (status active)
systemctl restart carbonio-ws-collaboration (status active)
systemctl restart carbonio-videoserver (status active)

2. PGPASSWORD=$DB_ADM_PWD carbonio-message-dispatcher-migration carbonio_adm 127.78.0.10 20000 (result: carbonio-message-dispatcher-migration: command not found)

3. added PGPASSWORD=$DB_ADM_PWD carbonio-files-db-bootstrap carbonio_adm 127.0.0.1
PGPASSWORD=$DB_ADM_PWD carbonio-tasks-db-bootstrap carbonio_adm 127.0.0.1
PGPASSWORD=$DB_ADM_PWD carbonio-ws-collaboration-db-bootstrap carbonio_adm 127.0.0.1
PGPASSWORD=$DB_ADM_PWD carbonio-message-dispatcher-db-bootstrap carbonio_adm 127.0.0.1
