/usr/bin/easy-add: 7: /usr/bin/easy-add: Syntax error: newline unexpected

[Yaimuu]

Hello ! I'm new to Dockefiles and I'm trying to use the command you created easy-add in my Dockerfile for a project but I'm getting this error permanently and I'm pretty sure it doesn't come from my code as the error is focusing on the "line 7". In fact I think that it comes from one of your files.

I would be very glad if could help me with my issue @itzg

[itzg]

easy-add is a binary executable. Add a RUN head /usr/bin/easy-add after the RUN chmod +x /usr/bin/easy-add to see what's going on there.

I'm getting this :

I don't really know what to do with this information...

I finally spotted the error in your Dockerfile. You copied this line wrong:

https://github.com/itzg/docker-minecraft-server/blob/9c6047e3fcda7f4d7d6780e6d0e1298a0223d477/Dockerfile#L39

Thanks ! It solved the error but do you know why the line :

RUN easy-add --var os=${TARGETOS} --var arch=${TARGETARCH}${TARGETVARIANT} \
    --var version=1.2.0 --var app=restify --file {{.app}} \
    --from https://github.com/itzg/{{.app}}/releases/tag/{{.version}}/{{.app}}_{{.version}}_{{.os}}_{{.arch}}.tar.gz

returns a non-zero code ?

Nevermind, I just had to install "ca-certificates" and add "RUN update-ca-certificates" before the line ! Thanks for your help !
