Needrestart hangs with LXD containers

[lenucksi]

I use needrestart with a standard Ubuntu 16.04 together with LXD (basically LXC+scripting, see https://linuxcontainers.org/lxd/ ) containers using the package provided by Ubuntu.
Needrestart runs fine, however hangs after the check started by aptitude.

SET needrestart/ui-query_conts LXC container/system.slice/avahi-daemon.service, LXC container/system.slice/dbus.service

It usually suffices to CTRL-C the process, however this is a problem with unattended updates...
#26 appears to be relevant to this case too.

This ends up locking apt-databases due to hanging nightly update jobs that can not properly terminate the package manager due this bug.

Hi,

you should never see the debconf stuff (SET ...) on you TTY. It seems something breaks the pipe setup between debconf and needrestart.

You are using needrestart 2.6, didn't you? There is a bug before needrestart 2.8 which was fixed by 0131e9f breaking debconf for the container selection.

I was actually using needrestart version 2.9.

Could you give git HEAD a try? You will find a most recently build Debian package attached to #54 (comment)

Thanks, I'll report a new status once I've got a situation that should trigger the bug.

Please use the offical packages 2.11-2 from jessie-backports or stretch for further troubleshooting. Thanks!

Could you try to bring that into Ubuntu or provide a Ubuntu PPA for it too?

[liske]

I'm not using Ubuntu at all so I'm not going to provide any PPA for it. I'll close this issue, feel free to reopen it if you where able to reproduce the bug with needrestart 2.11+ so we can do further debugging.
