Server Dockerfile build failure

Using Wasp 0.16.2.

Issue in .wasp/out/Dockerfile

The Dockerfile used to deploy the server docker container has a command to install the 'upx' package (Line 77) but fails.

In my GitHub actions log I'm seeing

'Unable to locate package upx'

My builds were working a few days ago, not sure why this is happening now.

I'm migrating from 0.14 which didn't have the extra 'user defined contents'.

Hi @Juan. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

----------------------
It sounds like you're experiencing an issue with the Dockerfile generated by Wasp 0.16.2 where it's trying to install the 'upx' package but failing with "Unable to locate package upx".

This appears to be related to changes in the default Dockerfile between Wasp versions. When migrating from 0.14 to 0.16.2, there have been changes to the Dockerfile structure that might be causing this issue.

Possible Solutions

Check your custom Dockerfile: If you have a custom Dockerfile in your project root, it might be appended to the default one generated by Wasp, potentially causing conflicts. As mentioned in the migration docs, when upgrading Wasp versions, you may need to update your custom Dockerfile to be compatible with the new version.
Inspect the generated Dockerfile: Run
```
wasp dockerfile
```
```
wasp dockerfile
```
to see what your project's (potentially combined) Dockerfile looks like. This will help you identify any issues or conflicts.
Add the missing package: You might need to modify your Dockerfile to ensure the correct repository is available for the 'upx' package. This could be related to the Alpine Linux version being used in the Docker image.
Customize the Dockerfile: As described in the deployment docs, you can create your own Dockerfile in the project's root directory to add extra steps or override existing ones.

Similar issues have been reported before with Docker builds in Wasp. For example, there was an issue with OpenSSL compatibility in GitHub issue #877 that was fixed in a subsequent release.

If you continue to have issues, you might want to join the Wasp Discord for more specific help with your deployment setup.

Let me know if you'd like more specific guidance on how to modify your Dockerfile to resolve this issue!

Ah duh...my mistake I did have a Dockerfile in my root for some local testing.
