Title:
apt-get update segmentation fault with backports
Status in apt package in Ubuntu:
Fix Released
Bug description:
I noticed starting yesterday (2015-06-11) that "apt-get update" would
give "segmentation fault" with exit code 139. "apt-get upgrade" would
also segfault with exit code 139.
Trying various things, if I comment out in /etc/apt/sources.lst:
deb http://archive.ubuntu.com/ubuntu precise-backports main restricted
universe multiverse
... "apt-get update" then works normally and "upgrade" will upgrade new
package revisions.
If I add back the backports line and "apt-get update", the segfaults will
start happening again.
This only happens on my 12.04 LTS systems. My 14.04 LTS systems do not
have any problems with backports.
My 12.04 systems include:
minimally installed laptop
minimally installed VPS
minimally installed firewall
minimally installed virtualbox vm
remastered live CD and its chroot master
remastered ubuntu-rescue-remix live CD and its chroot master
12.04 chroot for running older programs that won't work under 14.04
Since its happening to all the 12.04 installs I have, I think this is
widespread. I'm surprised there hasn't been a bug filed on it already.
"apt-cache policy" crashed until I removed backports and did an update
again.
I consider this to be a security issue as it was blocking me from
getting recent SSL/encryption updates that my 14.04 systems could get
without problems. As a whole, it would block all updates until
backports was removed.
I did a tar.gz of anything "backports" in /var and attached it. My
guess is that some kind of malformed entry in one of the apt
description files got corrupted somehow. These files should allow for
separate bug reproduction in case backports gets changed in the mean
time.
