Potentially missing shebang

[garnetgrimm]

Hey everyone. I'm fairly new to docker, so this might be my fault, but I'm fairly certain that one of the scripts here is missing the shebang and thus causes a Exec format error.

docker run --rm -it -v /home/garnet/Desktop/vsthwhost/elk/:/workdir crops/extsdk-container --url https://github.com/elk-audio/elkpi-sdk/releases/download/v0.6/elk-glibc-x86_64-elk-sika-image-dev-cortexa7t2hf-neon-vfpv4-raspberrypi3-toolchain-1.0.sh

@garnetgrimm is your host aarch64? Exec format error typically occurs when running a binary from a different architecture, such as trying to run an x86_64 container on a raspberry pi.

Hi !
I have the same issue, with the new version of the same script. The host is a x86_64. The shebang is in the script. Could it be that the script has no execution file system permission ?

[valentinlageard]

When inspecting the esdk-installer.sh, I found that it is empty suggesting that the download failed silently. Also, weirdly, when I try to execute the curl command (curl -# -o "/workdir/test.sh" github.com/elk-audio/elkpi-sdk/releases/download/0.11.0/elk-glibc-x86_64-elkpi-audio-os-image-cortexa72-raspberrypi4-64-toolchain-0.11.0.sh) manually inside the container, it gives a "permission denied"...

P.S.: whoami gives usersetup.

[valentinlageard]

Ok I think I've found the "error".

First of all, I've successfully ran the container using a predownloaded image, putting it in the volume and passing the absolute path.

Also, I've discovered that the github link uses a redirection. Curl thinks that everything went fine and downloads 0 bytes... The solution would be to add -L when curl is called in the function download_esdk. It would automatically resolve any redirections.
