[Help] Issue with Carbonio Tasks after Fresh Install (v25.3.1)

Hello everyone,

I'm currently trying to install Carbonio 25.3.1 as part of a migration from Zimbra. I'm following the official documentation for a single-node manual installation:

The installation process completes without errors. However, when I attempt to create a task via the WebUI, I can enter the task details, but after clicking "Save", nothing happens — the task is not created.

I checked the status of the carbonio-tasks service and found this:

● carbonio-tasks.service - Carbonio Tasks daemon

After that, the service ends up crashing (status changes to failed).

🧪 Additional Checks

I also tried the following command to inspect Consul KV entries:

consul kv get -recurse -token-file="/etc/carbonio/tasks-db/service-discover/token"

But it returns nothing, as if the necessary keys are missing.

I’ve already:

• Reinstalled from scratch 5 times

• Ensured all dependencies and prerequisites were met

• Looked through multiple forum threads, including this similar case:
  https://community.zextras.com/forum/carbonio-setup/upgrading-to-24-5-0-cannot-run-script-file-etc-carbonio-message-dispatcher-sql-scripts-migrations-6-0-0-sql/

Still, I’m stuck at the same point every time.

I've tried several thing to fix this issue but I'm unable to find... I've done the full clean install 5 times and every times I get this error.

Does anyone have an idea what could be missing or misconfigured?

Any help or guidance would be greatly appreciated.

Thanks in advance!
