[Bug 1992844] Re: apt download retries do not start at the 'root' but the redirect

It looks like you're running Raspbian, not Ubuntu. Please open a bug
with Raspbian instead.

Title:
  apt download retries do not start at the 'root' but the redirect

Status in apt package in Ubuntu:
  Invalid

Bug description:
  I am running apt with exactly one source and with the retries=3 option
  that became standard.

  
  ~ $ cat /etc/apt/sources.list.d/raspi.list 
  deb http://raspbian.raspberrypi.org/raspbian bullseye main

  ~ $ apt --version
  apt 2.2.4 (arm64)

  $ sudo apt-get -oAcquire::ForceIPv6=true -oAcquire::Retries=3 install
  --reinstall adduser

  
  Now the host of the repo will reply with a mirror selection (i.e. http 302 redirect). It so happens that the mirror selected is a ipv4 mirror and my machine is a ipv6 only machine, so there is no possible dns resolution. (force ipv6 was a trial, has no effect on my machine which is ipv6 only)

  Apt tries again 3 times, but only at the location of the redirect.

  For my understanding it should start at the original source, so it has
  a chance of getting a _different_ 302 redirect.
