Package: apt Version: 1.0.10.2 Severity: important Dear Maintainer,
When I upgrade to apt 1.1.3 or later (tested with both that and 1.1.4), and then run 'apt-get update' or 'apt update', I get results like the following: ======== Ign:1 http://ftp.us.debian.org/debian stable InRelease Hit:2 http://ftp.us.debian.org/debian testing InRelease Err:2 http://ftp.us.debian.org/debian testing InRelease Couldn't create tempfiles for splitting up /var/lib/apt/lists/ftp.us.debian.org_debian_dists_testing_InRelease Could not execute 'apt-key' to verify signature (is gnupg installed?)

They have been ignored, or old ones used instead. ======== As the below should indicate, I do have gnupg installed. Downgrading back to apt 1.0.10.2 (which is a manual process involving multiple passes with dpkg, due to dependency problems) restores functionality. A problem which looks like the same issue has been reported by an Ubuntu user: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1524196 The configuration information below was captured from a system where the downgrade back to 1.0.10.2 had been completed. The pins against apt and aptitude-common are to prevent dist-upgrades from bringing back the broken configuration again. As far as I'm aware, nothing about my system should prevent this from working. However, I've been unable to figure out how to get meaningful information about what is failing. If there is anything I can do to help track this down, please do not hesitate to let me know. -- Package-specific info: -- apt-config dump -- APT ""; APT::Architecture "amd64"; APT::Build-Essential ""; APT::Build-Essential:: "build-essential"; APT::Install-Recommends "1"; APT::Install-Suggests "0"; APT::Authentication ""; APT::Authentication::TrustCDROM "true"; APT::NeverAutoRemove ""; APT::NeverAutoRemove:: "^firmware-linux.*"; APT::NeverAutoRemove:: "^linux-firmware$"; APT::NeverAutoRemove:: "^linux-image-4\.1\.0-2-amd64$"; APT::NeverAutoRemove:: "^linux-image-4\.2\.0-1-amd64$"; APT::NeverAutoRemove:: "^linux-headers-4\.1\.0-2-amd64$"; APT::NeverAutoRemove:: "^linux-headers-4\.2\.0-1-amd64$"; APT::NeverAutoRemove:: "^linux-image-extra-4\.1\.0-2-amd64$"; APT::NeverAutoRemove:: "^linux-image-extra-4\.2\.0-1-amd64$"; APT::NeverAutoRemove:: "^linux-signed-image-4\.1\.0-2-amd64$"; APT::NeverAutoRemove:: "^linux-signed-image-4\.2\.0-1-amd64$"; APT::NeverAutoRemove:: "^kfreebsd-image-4\.1\.0-2-amd64$"; APT::NeverAutoRemove:: "^kfreebsd-image-4\.2\.0-1-amd64$"; APT::NeverAutoRemove:: "^kfreebsd-headers-4\.1\.0-2-amd64$"; APT::NeverAutoRemove:: "^kfreebsd-headers-4\.2\.0-1-amd64$"; APT::NeverAutoRemove:: "^gnumach-image-4\.1\.0-2-amd64$"; APT::NeverAutoRemove:: "^gnumach-image-4\.2\.0-1-amd64$"; APT::NeverAutoRemove:: "^.*-modules-4\.1\.0-2-amd64$"; APT::NeverAutoRemove:: "^.*-modules-4\.2\.0-1-amd64$"; APT::NeverAutoRemove:: "^.*-kernel-4\.1\.0-2-amd64$"; APT::NeverAutoRemove:: "^.*-kernel-4\.2\.0-1-amd64$"; APT::NeverAutoRemove:: "^linux-backports-modules-.*-4\.1\.0-2-amd64$"; APT::NeverAutoRemove:: "^linux-backports-modules-.*-4\.2\.0-1-amd64$"; APT::NeverAutoRemove:: "^linux-tools-4\.1\.0-2-amd64$"; APT::NeverAutoRemove:: "^linux-tools-4\.2\.0-1-amd64$"; APT::NeverAutoRemove:: "^postgresql-"; APT::VersionedKernelPackages ""; APT::VersionedKernelPackages:: "linux-image"; APT::VersionedKernelPackages:: "linux-headers"; APT::VersionedKernelPackages:: "linux-image-extra"; APT::VersionedKernelPackages:: "linux-signed-image"; APT::VersionedKernelPackages:: "kfreebsd-image"; APT::VersionedKernelPackages:: "kfreebsd-headers"; APT::VersionedKernelPackages:: "gnumach-image"; APT::VersionedKernelPackages:: ".*-modules"; APT::VersionedKernelPackages:: ".*-kernel"; APT::VersionedKernelPackages:: "linux-backports-modules-.*"; APT::VersionedKernelPackages:: "linux-tools"; APT::Never-MarkAuto-Sections ""; APT::Never-MarkAuto-Sections:: "metapackages"; APT::Never-MarkAuto-Sections:: "restricted/metapackages"; APT::Never-MarkAuto-Sections:: "universe/metapackages"; APT::Never-MarkAuto-Sections:: "multiverse/metapackages"; APT::Never-MarkAuto-Sections:: "oldlibs"; APT::Never-MarkAuto-Sections:: "restricted/oldlibs"; APT::Never-MarkAuto-Sections:: "universe/oldlibs"; APT::Never-MarkAuto-Sections:: "multiverse/oldlibs"; APT::Clean-Installed "false"; APT::Architectures ""; APT::Architectures:: "amd64"; APT::Architectures:: "i386"; APT::Compressor ""; APT::Compressor::.
