Package: autopkgtest
Version: 5.2
User: debian-ci@lists.debian.org
Usertags: issue
autopkgtest doesn't fail when apt can't install recommended packages.
This is caused by APT::Install-Recommends=true, which is what
autopkgtest uses to achieve this) not forcing apt to fail. apt can't be
forced to fail with that setting on missing recommends. Also that option
is transitive. Is that really wanted?
For a more detailed example, see the e-mail below.

Some details: in

starting at 'test command3: preparing testbed' we see

The test dependencies are just '@, pkg-perl-autopkgtest' with
'Restrictions: needs-recommends', so it's supposed to install
libsearch-elasticsearch-perl and its dependencies and recommendations.
The package Recommends libjson-xs-perl, which is uninstallable without
pulling libcommon-sense-perl:amd64 3.74-2+b5 from unstable. This doesn't
happen, so we get a failure:
# Failed test '/usr/bin/perl -wc
/usr/share/perl5/Search/Elasticsearch/Serializer/JSON/XS.pm exited

Similarly in
https://ci.debian.net/data/autopkgtest/testing/amd64/libp/libppi-perl/184151/log.gz
libppi-perl Recommends: libclass-xsaccessor-perl which is only
installable from unstable but doesn't get pulled in, which leads to a
failure. In this case apt is totally silent about the uninstallability
afaics.
