waveboxapp Linux APT repository serving bad header data

So this is what I've been seeing for the last week or so with the beta APT repository enabled in my sources.list.d directory:

$ sudo apt update
  …
  Ign:237 https://download.wavebox.app/beta/linux/deb amd64/ InRelease
  …
  Err:237 https://download.wavebox.app/beta/linux/deb amd64/ InRelease
  The HTTP server sent an invalid Content-Range header Bad header data [IP: 2606:4700:3030::6815:2816 443]
  …
  W: Failed to fetch https://download.wavebox.app/beta/linux/deb/amd64/InRelease  The HTTP server sent an invalid
  Content-Range header Bad header data [IP: 2606:4700:3030::6815:2816 443]

I'm rather curious to learn exactly what the nature of the invalid Content-Range value is, but if you'd rather just fix it on your end and never speak of it for as long as we both shall live, I'm totally cool with that. too. Here's what I'm able to offer towards ameliorating the situation...

The relevant IETF document is RFC 7233, specifically Section 4 which treats on instances of responding to range requests.
Since 2017, APT only parses the Content Range header field within code 206 and 416 HTTP responses.

The output of curl -6LD - "https://download.wavebox.app/beta/linux/deb/amd64/InRelease" is as follows:

And that's all I've got. Hopefully someone on your team sees what I'm not; it sure will be nice not to bump into that error in the terminal.

Same for stable repo since about yesterday:

The other ipv4 104.21.40.22 has the same issue.

Nevermind, apt clean (apt-get clean) fixed the issue.

Sometimes apt caches headers for some reason. It sounds like you ran into this. Thanks for letting me know you managed to get it working 👍
