Bug#953260: E: Could not perform immediate configuration on 'libgcc1:amd64'.

[Johannes 'josch' Schauer <josch@debian.org>]

Package: apt
Version: 1.9.10
Severity: normal

Hi,

recently mmdebstrap gained a new feature called --simulate which will
call apt with -oAPT::Get::Simulate=true. While this works fine in Debian
stable, it fails in current testing and unstable. To reproduce the
problem consider the Packages file at the end of this mail and the
following mmdebstrap command:

./mmdebstrap --verbose --dry-run --variant=essential . debian.tar "deb [trusted=yes] copy://$(pwd)/repo/ main ."

E: Could not configure 'libc6:amd64'. 
E: Could not perform immediate configuration on 'libgcc1:amd64'. Please see man 5 apt.conf under APT::Immediate-Configure for details. (2)


The apt command executed by mmdebstrap is essentialy:

APT_CONFIG=foo apt-get --yes -oApt::Get::Download-Only=true -oAPT::Get::Simulate=true install libc-bin

And where foo contains stuff along the lines of:

Apt::Architecture "amd64";
Apt::Architectures "amd64";
Dir "/tmp/mmdebstrap.Dt_RUrBC0g";
Dir::State::Status "/tmp/mmdebstrap.Dt_RUrBC0g/var/lib/dpkg/status";
Dir::Etc::Trusted "/etc/apt/trusted.gpg";
Dir::Etc::TrustedParts "/etc/apt/trusted.gpg.d/";
pkgCacheGen::ForceEssential ",";

I don't even know whether you care about this but the dependency
situation seems trivial so maybe this is actually an important bug?

Thanks!

cheers, josch
