Thank you for identifying the offending commit. The error you are
seeing could be caused by the second assignment in:
our $ARCHITECTURE = safe_qx(qw(dpkg-architecture -qDEB_HOST_ARCH));
...
$data->{architecture} = $ARCHITECTURE;
which happened in this commit:
https://salsa.debian.org/lintian/lintian/commit/8d1f6a0a6c3617b168f36cd1389b5ae2b3470d1e#c126e8eff5e7366571c744785275b8864017724f_1068_1067
What is the output of 'dpkg-architecture -qDEB_HOST_ARCH', please, on
the machines the failed architectures were building on? If the value
is 'amd64', you may be able to triage with:
$data->{architecture} = 'any'; (Please don't try 'all', as in the
commit; it won't work.)
Thank you!
Kind regards,
Felix Lechner
