Package: apt Version: 1.0.9.3 Followup-For: Bug #756162 I suspect this is the same underlying cause as the segfault that I was about to report. When running apt update without a network connection (such as right after suspend before wireless has come back on line), apt update segfaults at the end of processing:
mithrandir:/root# apt update Err http://linux.dropbox.com sid InRelease Err http://ftp.us.debian.org experimental InRelease Err http://ftp.us.debian.org unstable InRelease Err http://ftp.us.debian.org experimental Release.gpg Temporary failure resolving 'ftp.us.debian.org' Err http://linux.dropbox.com sid Release.gpg Temporary failure resolving 'linux.dropbox.com' Err http://archives.eyrie.org unstable InRelease Err http://ftp.us.debian.org unstable Release.gpg Temporary failure resolving 'ftp.us.debian.org' Err http://archives.eyrie.org unstable Release.gpg Temporary failure resolving 'archives.eyrie.org' Reading package lists... Done Segmentation fault (core dumped) This happens reliably every time I run apt update without a network connection. My guess is that this is triggering the same case of a reference to an underlying distribution that doesn't exist in any package list (since downloading all package lists failed). Sadly, the stack trace is not horribly useful: #0 0x00007f2cd1525980 in DoUpdate(CommandLine&) () from /usr/lib/x86_64-linux-gnu/libapt-private.so.0.0 #1 0x00007f2cd186efa6 in CommandLine::DispatchArg(CommandLine::Dispatch*, bool) () from /usr/lib/x86_64-linux-gnu/libapt-pkg.so.4.12 #2 0x00007f2cd1ccafce in ?? () #3 0x00007f2cd0954b45 in __libc_start_main (main=0x7f2cd1ccac90, argc=2, argv=0x7fff5e043998, init=<optimized out>, fini=<optimized out>, rtld_fini=<optimized out>, stack_end=0x7fff5e043988) at libc-start.c:287 #4 0x00007f2cd1ccb137 in ?? () It's trivial to reproduce this by just turning off all networking and then running apt update. -- Package-specific info: -- apt-config dump -- APT ""; APT::Architecture "amd64"; APT::Build-Essential ""; APT::Build-Essential:: "build-essential"; APT::Install-Recommends "0"; APT::Install-Suggests "0"; APT::Authentication ""; APT::Authentication::TrustCDROM "true"; APT::NeverAutoRemove ""; APT::NeverAutoRemove:: "^firmware-linux.*"; APT::NeverAutoRemove:: "^linux-firmware$"; APT::NeverAutoRemove:: "^linux-image-3\.16-3-amd64$"; APT::NeverAutoRemove:: "^linux-image-3\.16\.0-4-amd64$"; APT::NeverAutoRemove:: "^linux-headers-3\.16-3-amd64$"; APT::NeverAutoRemove:: "^linux-headers-3\.16\.0-4-amd64$"; APT::NeverAutoRemove:: "^linux-image-extra-3\.16-3-amd64$"; APT::NeverAutoRemove:: "^linux-image-extra-3\.16\.0-4-amd64$"; APT::NeverAutoRemove:: "^linux-signed-image-3\.16-3-amd64$"; APT::NeverAutoRemove:: "^linux-signed-image-3\.16\.0-4-amd64$"; APT::NeverAutoRemove:: "^kfreebsd-image-3\.16-3-amd64$"; APT::NeverAutoRemove:: "^kfreebsd-image-3\.16\.0-4-amd64$"; APT::NeverAutoRemove:: "^kfreebsd-headers-3\.16-3-amd64$"; APT::NeverAutoRemove:: "^kfreebsd-headers-3\.16\.0-4-amd64$"; APT::NeverAutoRemove:: "^gnumach-image-3\.16-3-amd64$"; APT::NeverAutoRemove:: "^gnumach-image-3\.16\.0-4-amd64$"; APT::NeverAutoRemove:: "^.*-modules-3\.16-3-amd64$"; APT::NeverAutoRemove:: "^.*-modules-3\.16\.0-4-amd64$"; APT::NeverAutoRemove:: "^.*-kernel-3\.16-3-amd64$"; APT::NeverAutoRemove:: "^.*-kernel-3\.16\.0-4-amd64$"; APT::NeverAutoRemove:: "^linux-backports-modules-.*-3\.16-3-amd64$"; APT::NeverAutoRemove:: "^linux-backports-modules-.*-3\.16\.0-4-amd64$"; APT::NeverAutoRemove:: "^linux-tools-3\.16-3-amd64$"; 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::Default-Release "unstable"; APT::Architectures ""; APT::Architectures:: "amd64"; APT::Compressor ""; APT::Compressor::.
