Title:
  "File has unexpected size" error on Focal ddebs repository

Status in apt package in Ubuntu:
  Confirmed

Bug description:
  Similar to https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1975865
  but affecting Ubuntu 20.04 "Focal"

  
  Steps to reproduce:

  1. Configure the debug repositories, like how it is explained in
  https://wiki.ubuntu.com/Debug%20Symbol%20Packages

  I ran these commands on a newly created Docker container (docker run
  --pull always --rm -ti ubuntu:20.04), but a typical bare metal
  installation should present the same issue:

  apt-get update ; apt-get install --yes gnupg

  apt-key adv \
      --keyserver keyserver.ubuntu.com \
      --recv-keys F2EDC64DC5AEE1F6B9C621F0C8CAB6595FDFF622

  source /etc/lsb-release

  tee /etc/apt/sources.list.d/ddebs.list >/dev/null <<EOF
  # Official Ubuntu repos with debug packages
  deb http://ddebs.ubuntu.com ${DISTRIB_CODENAME} main restricted universe multiverse
  deb http://ddebs.ubuntu.com ${DISTRIB_CODENAME}-updates main restricted universe multiverse
  EOF


  2. Try to run `apt-get update` with the new ddebs repo added:

  apt-get update

  Result is as follows:

  Further info as per the "Ubuntu bug reporting guidelines":

  1) Output from `lsb_release -rd`:
  Ubuntu 20.04.4 LTS

  2) Output from `apt-cache policy apt`:
    Installed: 2.0.6
    Candidate: 2.0.8
    Version table:
       2.0.8 500
          500 http://archive.ubuntu.com/ubuntu focal-updates/main amd64 Packages
   *** 2.0.6 100
          100 /var/lib/dpkg/status
       2.0.2ubuntu0.2 500
          500 http://security.ubuntu.com/ubuntu focal-security/main amd64 Packages
       2.0.2 500
          500 http://archive.ubuntu.com/ubuntu focal/main amd64 Packages

  (note, upgrading to the latest 2.0.8 doesn't make any difference)

  3) What I expected to happen:
  apt-get update works after adding the "ddebs" repository.

  4) What happened instead:
  apt-get update fails with a "File has unexpected size" error after adding the "ddebs" repository.
