Docker Container Issues

I've been trying to build a docker container for a while and I'm not sure what I'm doing wrong. No matter what I do I get something like this on the install mojo command. Any ideas?

Here is the file I was attempting to build

And building the container with this docker build --tag ark-guardian . docker run --env-file .env -p 8080:8080 ark-guardian I am running this from apple silicon though, could that be why? I thought now that it worked for apple silicon it should work in a docker container too Oh yep looks like that was the error, seems like mojo on ubuntu docker container is not friendly to apple silicon

Please consider editing your message to remove your Modular auth key -- these can be used to impersonate you.

Oh I thought I removed that, thanks. Good catch
