the regression seems to indicate a coreutils installation issue

Timing and artifacts indicates an lxc regression:

liblxc-common 3.0.0~beta2-0ubuntu2 BAD
liblxc-common 3.0.0~beta1-0ubuntu3 GOOD

[Christian Brauner (cbrauner)]

Can we get some logs for the LXC containers that created and fail? Otherwise this is very much a black box.

I was unable to recreate this failure when testing apport with the following command:

autopkgtest --shell-fail -U apport_2.20.8-0ubuntu10.dsc -- qemu /mnt/sec-machines/autopkgtest-bionic-amd64.img

I also just created the .img file via:

autopkgtest-buildvm-ubuntu-cloud -a amd64 -r bionic -o /mnt/sec-machines/ -m http://192.168.10.7/ubuntu

I see the latest apport test ran successfully, maybe the bug solved by unrelated changes, lets auto-close this bug in 59 days unless it happens again (I retried the failed tests a few seconds ago)

[Gianfranco Costamagna (costamagnagianfranco)]

I retried and the succeeded, closing
