Curl Downloads tar.gz file as ASCII

Question

I'm trying to download a tar.gz file from a github repo with curl, but it's evidently downloading plain ASCII and so I can't unzip or untar the file (as evidenced by the file command - see the third line of my stack trace below).

One other important detail is that this is running inside an AWS CodeBuild instance. However, I can download this with curl just fine on my mac and it is a proper tar.gz file.

Here's the command I'm running:

curl -Lk0s https://github.com/gohugoio/hugo/releases/download/v0.49/hugo_0.49_Linux-64bit.tar.gz -o /tmp/hugo.tar.gz

The full stack trace is:

What am I doing wrong here?

Answer 1

-L works for me:

curl -L https://github.com/gohugoio/hugo/releases/download/v0.49/hugo_0.49_Linux-64bit.tar.gz -o /tmp/hugo.tar.gz

I tried it without any flags first and it downloaded the redirection page.

Added -L to follow redirects and the result was a well-formed, complete .tar.gz file that decompressed perfectly. The result was a folder with a few files in it:

$ ls -l
total 41704
-rw-r--r--  1 xxxxxxxxxxx  staff     11357 Sep 24 05:54 LICENSE
-rw-r--r--  1 xxxxxxxxxxx  staff      6414 Sep 24 05:54 README.md
-rwxr-xr-x  1 xxxxxxxxxxx  staff  21328256 Sep 24 06:03 hugo

UPDATE: I didn't at first try your set of params (-Lk0s) assuming it wouldn't work for me either. But I just now tried it and it works for me. I get the same .tar.gz that I got with -L and it decompresses accurately. Please cat the contents of the text file that gets downloaded and show at least some of it here. It's probably an error of some sort being sent back as plain text or html.
