Package: apt Version: 1.0.9.8.4 Severity: critical
--- Please enter the report below this line. --- I use Debian 8 64bit with GNOME installed with standard install procedure from netinstall and using tasksel. This occured to me the second time. First time was a year ago, I reinstalled Debian then and a year after this happens again. Both occurences were on Debian 8, stable at the time. They were installed from the stable repo, I have logs of that. I did not make any changes to my system lately and I generally do not tinker. The only new packages that I installed during recent month were mktorrent, mediainfo Backports repo was pinned to 100 according to apt-cache policy after system installation and now too, after the bug occured. I did not change pinning settings ever on this machine nor any other. # TLDR Every package on system gets updated to the version from backports silently (yes, I did click the upgrade button without checking if the right versions are installed of each package) even though backports repo is pinned to 100. This results in slow breakage of everything, max few days to make the machine useless to do work as usual. # Description of what happened Few days ago (it's worth noting that the machine was on for perhaps a week and package upgrades were performed) I noticed that hibernation stopped working on my system for no apparent reason. Every time after I hibernated the machine, upon booting it restarted and then at the next boot ext4 was performing fs check and repairing lots of errors. The next thing I noticed was that disk IO became extremely slow. It's the most stable consumer SSD available at the moment, Intel 730. It performed no problem before, but now if I move 100 or even 50 files, bunch of kilobytes in size (together 1MB) the operation can take a minute or even more. No noticeable disk problems with playing 1080p videos or browsing the web. Another system on this machine (Windows) doesn't seem to exhibit similar issues. Next thing is a message asking if software upgrades should be installed when I click the power off button in GNOME. Next boot it installs them, but system crashes. Then when I boot again, ext4 check and repair and lots of errors. BTW While writing this, I clicked that GNOME power button and canceled, clicked again, window didn't appear and the system turned itself off. Evolution email client started showing folders I disabled and some errors about cache (missing or something). Firefox signed me out from every single website. I became worried about what's happening with my machine, tried apt-get update and upgrade manually (I normally use apt-config-auto-update), that's what upgrade says "The following packages have been kept back: linux-image-amd64". So it occured to me that it may be the same bug that killed my machine a year ago, I runned "dpkg -l |awk '/^ii/ && $3 ~ /bpo[6-8]/ {print $2}'" to see what backports are installed, and yes, every package that has a backport version available was switched to that version silently and apt-cache policy still says backports are pinned to 100! This is exactly what happened a year ago. The only sane fix for this machine now is a complete reinstall. Worth noting that a year ago this made dpkg unusable, ie. no package could be installed or upgraded because of dependency breakage. # List of backports installed. Before that the only backports I had on my system were: apt-config-auto-update (installed it with apt-get -t jessie-backports install), python-idna (automatically installed with torbrowser-launcher), python-axolotl (installed with apt-get install python-axolotl). Now "dpkg -l |awk '/^ii/ && $3 ~ /bpo[6-8]/ {print $2}'" shows this: apt-config-auto-update autopoint calibre calibre-bin dh-python dmidecode e2fslibs:amd64 e2fsprogs exfat-fuse exfat-utils ffmpeg firmware-realtek fonts-opensymbol geoip-database gettext gettext-base gir1.2-gdata-0.0:amd64 hexchat hexchat-common hoichess i965-va-driver:amd64 ifupdown inkscape libapparmor1:amd64 libasprintf-dev:amd64 libasprintf0c2:amd64 libav-tools libavcodec57:amd64 libavdevice57:amd64 libavfilter6:amd64 libavformat57:amd64 libavresample3:amd64 libavutil55:amd64 libbluray1:amd64 libbrlapi0.6:amd64 libchromaprint1:amd64 libcomerr2:amd64 libcomerr2:i386 libdrm-amdgpu1:amd64 libdrm-amdgpu1:i386 libdrm-intel1:amd64 libdrm-intel1:i386 libdrm-nouveau2:amd64 libdrm-nouveau2:i386 libdrm-radeon1:amd64 libdrm-radeon1:i386 libdrm2:amd64 libdrm2:i386 libegl1-mesa:amd64 libfastjson4:amd64 libgbm1:amd64 libgdata-common libgdata22:amd64 libgeoip1:amd64 libgettextpo-dev:amd64 libgettextpo0:amd64 libgl1-mesa-dri:amd64 libgl1-mesa-dri:i386 libgl1-mesa-glx:amd64 libgl1-mesa-glx:i386 libglapi-mesa:amd64 libglapi-mesa:i386 libgles1-mesa:amd64 libgles2-mesa:amd64 libglib2.0-0:amd64 libglib2.0-bin libglib2.0-data libgphoto2-6:amd64 libgphoto2-l10n libgphoto2-port12:amd64 libjs-sphinxdoc libllvm3.8:amd64 libllvm3.8:i386 liblognorm5:amd64 libmediaart-2.0-0:amd64 libmtp-common libmtp-runtime libmtp9:amd64 libmysqlclient18:amd64 libnet-dbus-perl libnss-myhostname:amd64 libpam-systemd:amd64 libpcap0.8:amd64 libpostproc54:amd64 libpulse-mainloop-glib0:amd64 libpulse0:amd64 libpulsedsp:amd64 libreoffice libreoffice-avmedia-backend-gstreamer libreoffice-base libreoffice-base-core libreoffice-base-drivers libreoffice-calc libreoffice-common libreoffice-core libreoffice-draw libreoffice-evolution libreoffice-gnome libreoffice-help-en-us libreoffice-impress libreoffice-java-common libreoffice-math libreoffice-report-builder-bin libreoffice-sdbc-hsqldb libreoffice-style-galaxy libreoffice-style-tango libreoffice-writer librygel-core-2.6-2 librygel-renderer-2.6-2 librygel-renderer-gst-2.6-2 librygel-server-2.6-2 libseccomp2:amd64 libss2:amd64 libssl1.0.0:amd64 libswresample2:amd64 libswscale4:amd64 libsystemd0:amd64 libudev1:amd64 libudev1:i386 libva-drm1:amd64 libva-x11-1:amd64 libva1:amd64 libvdpau1:amd64 libwayland-egl1-mesa:amd64 libwine:amd64 libx265-87:amd64 libxapian22:amd64 libxatracker2:amd64 libxnvctrl0:amd64 linux-base linux-image-4.7.0-0.bpo.1-amd64 linux-image-amd64 linux-libc-dev:amd64 manpages manpages-dev mysql-common openssl pinentry-gtk2 pulseaudio pulseaudio-module-x11 pulseaudio-utils python-axolotl python-axolotl-curve25519 python-cffi-backend python-cryptography python-dateutil python-debianbts python-dnspython python-idna python-ipaddress python-openssl python-pil:amd64 python-pkg-resources python-psutil python-pyasn1 python-pygments python-pysimplesoap python-routes python-serial python-setuptools python-six python-twisted python-twisted-bin python-twisted-core python-webob python3-brlapi python3-pkg-resources python3-six python3-uno rsyslog rygel rygel-playbin rygel-tracker shared-mime-info systemd systemd-sysv tar tor tor-geoipdb torbrowser-launcher torsocks udev uno-libs3 unoconv ure usb-modeswitch usb-modeswitch-data va-driver-all:amd64 vdpau-va-driver:amd64 wine wine64 xbrlapi xserver-xorg-video-intel --- System information. --- Architecture: amd64 Kernel: Linux 4.7.0-0.bpo.1-amd64 Debian Release: 8.6 500 unstable ftp.gajim.org 500 unstable download.jitsi.org 500 stable-updates ftp.pl.debian.org 500 stable security.debian.org 500 stable ftp.pl.debian.org 100 jessie-backports ftp.pl.debian.org --- Package information. --- Depends (Version) | Installed =========================================-+-=============== libapt-pkg4.12 (>= 1.0.9.8.2) | 1.0.9.8.4 libc6 (>= 2.15) | libgcc1 (>= 1:4.1.1) | libstdc++6 (>= 4.9) | debian-archive-keyring | gnupg | Package's Recommends field is empty.
