Hey Steve, Julian,
I was reading again those steps Christian shared a while ago and noticed
the current archive autopkgtest version still doesn't implement the '-a'
option.
It seems
https://code.launchpad.net/~ubuntu-release/autopkgtest/+git/development/+merge/376169
got an ack 3 years ago, is there anything blocking the merge?
I've added the notes on
https://wiki.ubuntu.com/ProposedMigration#How_do_we_debug_i386_issues
because it's not the first time I have to figure that again and it's
probably the same for others. It would be nice it things working with
the archive version of autopkgtest
Cheers,
Sebastien

Hi,
The i386 removal works great and after the dust settled it comes
mostly down to adding a few more hints in recent weeks. But sometimes
there are i386 tests that are valid to run, but fail and need debugging.
If you happen to face such a case the old common pattern won't work
anymore:
$ sudo autopkgtest-buildvm-ubuntu-cloud -a i386 -r bionic -s 15G
$ sudo ~/work/autopkgtest/autopkgtest/runner/autopkgtest <YOUR>.dsc \
-- qemu ~/work/autopkgtest-focal-amd64.img
The above was fine in the past, but with Focal you that won't work due to:
$ sudo autopkgtest-buildvm-ubuntu-cloud -a i386 -r focal -s 15G

No image exists for this release/architecture
Steve was so kind to help me with the case I was facing and after a
bit I learned how to locally run my i386 tests in a VM and wanted to
share that with you.
First of all, you probably need a more recent autopkgtest to get the
features you need.
So you need to clone git and run it from there.
$ git clone
git+ssh://pael...@git.launchpad.net/~ubuntu-release/autopkgtest/+git/development
<http://pael...@git.launchpad.net/~ubuntu-release/autopkgtest/+git/development>
[for me that is in ~/work/autopkgtest/autopkgtest]
And then - since you only have amd64 images - to run it you have to add
# to select the architecture for the test
-a i386
# to get the arch available in the test env before the testing starts
--setup-commands="dpkg --add-architecture i386; apt-get update"
Overall for me it then worked like:
$ sudo ~/work/autopkgtest/autopkgtest/runner/autopkgtest <YOUR>.dsc \
--setup-commands="dpkg --add-architecture i386; apt-get update" -a
i386 \
-- qemu ~/work/autopkgtest-focal-amd64.img
I hope this helps some other people as well.
And if anyone knows more tweaks to get this local i386 test to run
even better please reply and let us all know.
P.S. of course my commandline never is that simple, the above is just
for illustration.
In reality it was more like:
$ sudo ~/work/autopkgtest/autopkgtest/runner/autopkgtest
--no-built-binaries --apt-upgrade --apt-pocket=proposed=src:re2c
--setup-commands="dpkg --add-architecture i386; apt-get update"
--shell-fail -a i386 re2c_1.3-1.dsc -- qemu --qemu-options='-cpu host'
--ram-size=2048 --cpus 2 ~/work/autopkgtest-focal-amd64.img
