Package: ifupdown Version: 0.8.1 Severity: important Hello,
after upgrading to 0.8.1 the dhclient command line changed to "dhclient -v -pf /run/dhclient.eth1.pid -lf /var/lib/dhcp/dhclient.eth1.leases \ -I -D LLT -df /var/lib/dhcp/dhclient6.eth1.leases eth1" Because of the "-D LLT" argument dhclient is unable to retrieve an IP4 address, at least in my environment. When I run the exact same command omitting the "-D LLT" argument everything works fine and IP6 as well as IP4 addresses can be acquired. Also, downgrading to 0.7.54 fixes the problem, since the dhclient command line looks like this then: "dhclient -v -pf /run/dhclient.eth1.pid -lf /var/lib/dhcp/dhclient.eth1.leases eth1". I don't understand exactly what the -D option does, but it leads to an unusable system with unconfigured network interface and no nameserver in resolv.conf. Please let me know if you need additional information to track down this issue. Thanks, Andreas. ~$ cat /etc/network/interfaces auto lo iface lo inet loopback auto eth1 iface eth1 inet dhcp -- System Information: Debian Release: stretch/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 4.3.0 (SMP w/8 CPU cores) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages ifupdown depends on: ii adduser 3.113+nmu3 ii iproute2 4.3.0-1 ii libc6 2.21-1 ii lsb-base 9.20150917 Versions of packages ifupdown recommends: ii isc-dhcp-client [dhcp-client] 4.3.3-5 ii pump [dhcp-client] 0.8.24-7 Versions of packages ifupdown suggests: pn ppp <none> pn rdnssd <none> -- Configuration Files: /etc/default/networking changed: VERBOSE=yes /etc/network/if-down.d/upstart [Errno 2] Datei oder Verzeichnis nicht gefunden: u'/etc/network/if-down.d/upstart' /etc/network/if-up.d/upstart [Errno 2] Datei oder Verzeichnis nicht gefunden: u'/etc/network/if-up.d/upstart' -- no debconf information
