[Pkg-rust-maintainers] Bug#1091267: rust-libphosh-sys: FTBFS on armhf: build-dependency not installable: phosh-dev (= 0.43.0-3)

[Lucas Nussbaum]

Source: rust-libphosh-sys
Version: 0.0.3-2
Severity: serious
Justification: FTBFS

Hi,

During a rebuild of all packages in sid, this package failed to build
on armhf.

This package currently has binary packages on armhf, so this is a regression.
Also, there are no known issues on amd64 or arm64 according to recent (a couple
days ago) rebuilds.

The rebuild was done using an armhf chroot on an AWS "m6g" instance (Graviton2
CPU).

Relevant part (hopefully):
