Bug Description

It took about 30 minutes for me to download the packages for a distro upgrade, yet it reports it took 6 seconds.

I'm upgrading from Disco to Eoan test version, using the command

  sudo do-release-upgrade -d

Excerpt from the output:

  7 packages are going to be removed. 81 new packages are going to be
  installed. 1940 packages are going to be upgraded.

  You have to download a total of 1,964 M. This download will take
  about 4 hours with a 1Mbit DSL connection and about 3 days 4 hours
  with a 56k modem.

The last line is faulty. The actual time was maybe about 30 minutes, not 6 seconds :-D

Note that the two other values shown in the last line, namely the overall size and the average download speed seem to be correct, and dividing these two indeed gives about 30 minutes.
