Hi, I'm not sure if this is what the original report was about, but this is a problem I have in Jessie, and seems to be resolved in Stretch.
I create an armhf chroot using qemu-debootstrap. Installing postfix in it fails with the same error message. There's an existing bug report in Ubuntu about it with more details: https://bugs.launchpad.net/ubuntu/+source/postfix/+bug/1531299 It seems qemu fails to implement a certain kernel detail needed for netlink. I didn't dig deep enough down there to see why it was needed for newaliases. Reproduced in Jessie's postfix (2.11.3-1). Not reproduced with the version in Stretch (3.1.3-2). Both using the version of qemu in Stretch (qemu-user-static 1:2.7+dfsg-3). To reproduce: 0. Pre-requirements: apt install qemu-user-static deboostrap 1. create a new chroot: debootstrap --arch=armhf $DISTRO root-dir 2. install postfix in it: # for those without systemd: configure schroot. Or maybe even a plain # chroot would do: systemd-nspawn -D root-dir -- apt install postfix -- Tzafrir Cohen | tzaf...@jabber.org | VIM is http://tzafrir.org.il | | a Mutt's tzaf...@cohens.org.il | | best tzaf...@debian.org | | friend
