[Pkg-rust-maintainers] Bug#947903: rust-cbindgen: autopkgtest failure: can't create /usr/share/cargo/registry/cbindgen-0.12.1/tests/expectations/alias.compat.o: Permission denied

[Paul Gevers]

Source: rust-cbindgen
Version: 0.9.0-1
X-Debbugs-CC: debian-ci at lists.debian.org
Severity: important
User: debian-ci at lists.debian.org
Usertags: regression

Dear maintainers,

Since version 0.9.0-1 rust-cbindgen has an autopkgtest, great. However,
it fails since its introduction. I copied some of the output at the
bottom of this report.

Normally these failures are blocking the migration to testing [1],
however, I want thunderbird to finally migrate to testing, so I have
ignored this failure, but can you please investigate the situation and
fix it? In principle this bug should be "serious", but then it would
block migration again, hence I filed it as important.

Paul
