Bug#849382: [apt] Every package on the system gets silently upgraded to backports. The result is severe system breakage, malfunctioning and data loss.
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:
