To be completed by the original poster:
# CMS Version 3.3.3
# Installation Method
Docker
# Operating System
Ubuntu
# Issue
After trying an upgrade without luck, I tried to rollback.
After restoring the old files and trying to start the installation, it gives me “Fatal Error - sorry this shouldn’t happen.
SQLSTATE[HY000] [2002] php\_network\_getaddresses: getaddrinfo failed: Try again” in my browser.
When I check the logs, I see the following:
cms-web\_1 | Configuring Database Settings
cms-web\_1 | ERROR 2005 (HY000): Unknown MySQL server host ‘mysql’ (-3)
I found a topic that also has this problem, but it’s on windows. [Xibo CMS unable accessing mysql docker instance](https://community.xibo.org.uk/t/xibo-cms-unable-accessing-mysql-docker-instance/25027)
Can anyone help me with this? Or at least point me in the right direction?
Thank you so much!
Kind regards
— UPDATE
I found some more post regarding this problem. I am now trying the solution given here:
> [@Unknown MySQL server host 'mysql'](https://community.xibo.org.uk/t/unknown-mysql-server-host-mysql/31013/5):
>
> OK - I found the solution. I edit the docker-compose.yml file and add a aliases flag for the cms-db service. Now the cms-db Container is linked in the cms-web Container again with “mysql” and everything is working as before. And the reason it took so long for me to find the solution was: I didn’t understand how to access the default network, because the examples I found always mention a concrete docker network. So I missed the keyword “default” and my tries failed. cms-db: image: …
If anyone still has a better idea, please let me know!
Thanks!

The solution I tried did not work. Does anyone else have a solution for me?

Sorry, I’m not a regular user of this forum and missed your question.
Actually I also just did an update again and it works perfect with this changes. I hope they do update the docker config sometimes
