Based on the information in your logs, the Airbyte bootloader is unable to connect to the PostgreSQL database, even though the database logs indicate it is ready and listening on port 5432. This is a common issue reported by other Airbyte users, and it can be caused by several factors related to permissions, networking, or Docker/Kubernetes setup. Here are some troubleshooting steps and considerations based on the knowledge sources: 1. Database Permissions and Ownership - Several users have encountered issues where the PostgreSQL data directory has incorrect permissions or ownership, preventing the database from starting or accepting connections. Even if the logs say "ready for start up," permission issues can still cause connectivity problems for other pods. - One workaround that has helped users is to manually set the ownership of the Airbyte database volume to the

postgres

user (UID 70). For example:

bash      sudo chown -R 70:70 ~/.airbyte/abctl/data/airbyte-volume-db

This should be run on the host machine where Airbyte is installed. After changing the ownership, try running

abctl local install

again. This solution is referenced by users who faced similar issues on both Ubuntu and cloud VMs [see here](https://github.com/airbytehq/airbyte/issues/62093). 2. Docker Installation Method - If you installed Docker using Snap, it can cause permission and networking issues due to AppArmor restrictions. Removing the Snap version and installing Docker via

apt

has resolved similar issues for other users. Make sure Docker and Docker Compose are installed using the recommended method for your OS [see here](https://discuss.airbyte.io/t/2305). 3. Port Conflicts - Ensure that no other PostgreSQL instance is running on port 5432 on your host, as this can cause binding issues or conflicts inside the Airbyte containers. You can check for running PostgreSQL processes and stop them if necessary. 4. Kubernetes/Kind Networking - Sometimes, the internal networking between pods in the kind cluster can fail. Restarting the installation after ensuring all previous Airbyte resources are cleaned up (

abctl local uninstall

and then

abctl local install

) can help. 5. Verbose Logs - Run the install command with

--verbose

to get more detailed logs, which might provide additional clues:

bash      abctl local install --verbose

If you have already checked the above and the issue persists, please provide any additional error messages from the bootloader or database logs after applying these steps. Summary: The most common and effective fix reported is to ensure the Airbyte database volume directory is owned by UID 70 (

postgres

). If you are using Snap for Docker, switch to the apt version. Also, check for port conflicts and try a clean uninstall/reinstall cycle. These steps have resolved similar issues for other users on Ubuntu and cloud VMs. If these steps do not resolve your issue, the knowledge sources do not provide a more specific solution for your exact scenario, and you may need to open a new issue with detailed logs for further assistance. --- References integrated from: - [Permission issue while installing Airbyte with abctl](https://github.com/airbytehq/airbyte/issues/62093) - [Docker Won't Start PostgreSQL on Ubuntu 22.04](https://discuss.airbyte.io/t/2305)
