Package: apt Version: 1.0.9.8.3 Severity: important Dear Maintainer,
Running `apt list -upgradable`, as a regular user (without CAP_DAC_OVERRIDE) led to a segfault when `/etc/apt/preferences.d/unbound` wasn't world-readable. Making that file world-readable made the issue disappear. The entire configuration of the machine exhibiting the issue is available at https://github.com/hashbang/shell-etc/tree/5ce59efb07972588fa10e730b4a945b2cded44bb Best regards, Keller Fuchs -- Package-specific info: -- apt-config dump -- APT ""; APT::Architecture "amd64"; APT::Build-Essential ""; APT::Build-Essential:: "build-essential"; APT::Install-Recommends "false"; APT::Install-Suggests "false"; APT::Authentication ""; APT::Authentication::TrustCDROM "true"; APT::NeverAutoRemove ""; APT::NeverAutoRemove:: "^firmware-linux.*"; APT::NeverAutoRemove:: "^linux-firmware$"; APT::NeverAutoRemove:: "^linux-image-3\.16\.0-4-amd64$"; APT::NeverAutoRemove:: "^linux-headers-3\.16\.0-4-amd64$"; APT::NeverAutoRemove:: "^linux-image-extra-3\.16\.0-4-amd64$"; APT::NeverAutoRemove:: "^linux-signed-image-3\.16\.0-4-amd64$"; APT::NeverAutoRemove:: "^kfreebsd-image-3\.16\.0-4-amd64$"; APT::NeverAutoRemove:: "^kfreebsd-headers-3\.16\.0-4-amd64$"; APT::NeverAutoRemove:: "^gnumach-image-3\.16\.0-4-amd64$"; APT::NeverAutoRemove:: "^.*-modules-3\.16\.0-4-amd64$"; APT::NeverAutoRemove:: "^.*-kernel-3\.16\.0-4-amd64$"; APT::NeverAutoRemove:: "^linux-backports-modules-.*-3\.16\.0-4-amd64$"; APT::NeverAutoRemove:: "^linux-tools-3\.16\.0-4-amd64$"; 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::Architectures ""; APT::Architectures:: "amd64"; APT::Compressor ""; APT::Compressor::.
