Well, one part of it is that Flatpak pulls data over the network, and sometimes data sent over a network doesn't arrive in the exact same shape as when it left the original system, which results in that same data being sent in multiple copies - until one manages to arrive correctly.

Could also be that the HTTP server lied about the content length.

It's a protocol violation to do that, not least because it precludes connection reuse

Hence why Fedora Linux actually recently removed delta updates for DNF. Turns out it used more data in retries than just downloading a whole package again.

Interesting, didnt know that! That sounds like a fixable issue though...

[-] Hujaj@lemmynsfw.com 2 points 7 months ago

I think they have moved from trying to fix it in DNF, to using the capabilities found in BTRFS for Copy on write. Can't quite remember exactly.

  • Understand the difference between a joke and an insult.
  • Do not harrass or attack members of the community for any reason.
  • Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
  • Bigotry will not be tolerated.
  • These rules are somewhat loosened when the subject is a public figure. Still, do not attack their person or incite harrassment.
  • 3. Post Linux-related content
  • Including Unix and BSD.
  • Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of sudo in Windows.
  • No porn. Even if you watch it on a Linux machine.
  • 4. No recent reposts
  • Everybody uses Arch btw, can't quit Vim, and wants to interject for a moment. You can stop now.
