Hi Team,

We are trying to upgrade our on premise instance from the below version.  
3.2.0.beta5-dev to 3.5.0.beta7

And we are seeing the below error.

/var/discourse# ./launcher rebuild app  
ERROR: Docker version 18.06.1-ce not supported, please upgrade to at least 20.10.0, or recommended 24.0.7

Please help in getting this sorted out as we need to upgrade our instance on priority to address few vulnerabilities found in the current version.

I think you need to update your Git version.

Your OS is almost certainly out of date too.

The easiest thing is to create a new VM with a new OS and a new Docker, install Discourse and restore a backup.

It’s possible that you can upgrade docker and try again, but you’ll still need to deal with the [PostgreSQL 15 update](https://meta.discourse.org/t/postgresql-15-update/349515). Moving to a new server will require little downtime and zero chance of leaving your system in a broken state.
