Public bug reported:

This happens for me with version 5.28ubuntu1 of autopkgtest on my Lunar system. The failure happens as follows:
The script downloads the file, reaches 100% download capacity and then exits with the message "Download failed!", shown below:
```
andersson123@duckstation7:~/canonical/code/autopkgtest/tools$ sudo ./autopkgtest-buildvm-ubuntu-cloud -a amd64 -r mantic -s 10G
[sudo] password for andersson123: 
WARNING: cannot determine development release, falling back to latest stable
Downloading https://cloud-images.ubuntu.com/mantic/current/mantic-server-cloudimg-amd64.img...

Download failed!
```
Upon further inspection, I discovered the conditional statement responsible for this is here:
https://salsa.debian.org/ci-team/autopkgtest/-/blob/master/tools/autopkgtest-buildvm-ubuntu-cloud#L204

I added a print statement to show the http header, and the fields the if statement were searching for weren't in it:
```

```

I then commented out this if statement, ran the script again and it
succeeded to build the image without any problems, so I question the
necessity of this if statement, although I haven't dug much deeper into
the code to understand it.

I then tried the same console command on my jammy system, with
autopkgtest version 5.20ubuntu1. It succeeded without the same error. I
then installed version 5.28ubuntu0.22.04.0 from jammy-proposed on my
jammy system, ran the same command and then got the same error as on my
lunar system.

I tried the command with different releases, i.e. building a jammy,
kinetic, lunar and mantic .img file, but it failed for all of these,
which leads me to believe it'd fail for all releases.
