debootstrapping vivid under fakechroot fails

[Martin Pitt]

$ fakeroot fakechroot debootstrap --variant=fakechroot vivid /tmp/vivid http://archive.ubuntu.com/ubuntu/

Perhaps we can fix chfn like in https://bugs.debian.org/745082, or perhaps change systemd to use "useradd" only.

Workaround:

$ cat ~/fakechroot-touch/debootstrap.env
. /etc/fakechroot/debootstrap.env
FAKECHROOT_CMD_SUBST="$FAKECHROOT_CMD_SUBST:/usr/bin/chfn=/bin/true"

fakeroot fakechroot -c ~/fakechroot-touch/ debootstrap --variant=fakechroot vivid /tmp/vividfc http://archive.ubuntu.com/ubuntu/

I jumped the gun here. The fix either didn't make its make into Ubuntu, or it was not an adequate fix.

Jammy:

chfn: PAM: Authentication failure
adduser: `/bin/chfn -f systemd Time Synchronization systemd-timesync' returned error code 1. Exiting.
dpkg: error processing package systemd-timesyncd (--configure):
 installed systemd-timesyncd package post-installation script subprocess returned error exit status 1

Can someone please reopen this?
