In my experience, I have found two potential issues when installing Ubuntu 18.04 using FAI.
The first is that if using FAI <= 5.5, then FAI_DEBOOTSTRAP_OPTS needs '--include gnupg'. Otherwise, the `apt-key add` in /usr/lib/fai/subroutines would fail. (At our site, we always run deboostrap instead of relying on basefiles, and we often need backwards compatibility for dirinstalls.) The second is that netplan (see https://netplan.io/examples) is the new preferred configuration format for networking; /etc/network/interfaces works only if you install the ifupdown package. I've included excerpts from our local scripts/DEBIAN/30-interface file below. It generates either /etc/netplan/*.yaml or /etc/network/interfaces.d/* or /etc/network/interfaces configuration files as appropriate. ############################################################################### netplan_yaml() { local IFNAME="$1" local METHOD="$2" echo "Generating netplan configuration for $IFNAME ($METHOD)" >&2 echo "# generated by FAI" echo "network:" echo " version: 2" ifclass SERVER || echo " renderer: NetworkManager" echo " ethernets:" echo " $IFNAME:" case "$METHOD" in dhcp) echo " dhcp4: true" ;; static) echo " addresses: [$CIDR]" echo " gateway4: $GATEWAYS_1" echo " nameservers:" echo " search: [$DOMAIN]" echo " addresses: [${DNSSRVS// /, }]" ;; esac } iface_stanza() { local IFNAME="$1" local METHOD="$2" echo "Generating interface configuration for $IFNAME ($METHOD)" >&2 echo "# generated by FAI" echo "auto $IFNAME" echo "iface $IFNAME inet $METHOD" case "$METHOD" in static) echo " address $IPADDR" echo " netmask $NETMASK" echo " broadcast $BROADCAST" echo " gateway $GATEWAYS" ;; esac } … case "$FAI_ACTION" in install|dirinstall) ifclass DHCPC && METHOD=dhcp || METHOD=static if [ -d $target/etc/netplan ]; then # Ubuntu >= 17.10 with netplan.io if [ -n "$NIC1" ]; then netplan_yaml $NIC1 $METHOD > $target/etc/netplan/01-${NIC1}.yaml fi elif [ -d $target/etc/network/interfaces.d ]; then # ifupdown >= 0.7.41 (Debian >= 8, Ubuntu >= 14.04) iface_stanza lo loopback > $target/etc/network/interfaces.d/lo if [ -n "$NIC1" ]; then iface_stanza $NIC1 $METHOD > \ $target/etc/network/interfaces.d/$NIC1 fi else ( iface_stanza lo loopback iface_stanza $NIC1 $METHOD ) > $target/etc/network/interfaces fi if ! ifclass DHCPC ; then [ -n "$NETWORK" ] && echo "localnet $NETWORK" > $target/etc/networks if [ ! -L $target/etc/resolv.conf -a -e /etc/resolv.conf ]; then cp -p /etc/resolv.conf $target/etc fi fi ;; esac ############################################################################### > On May 18, 2018, at 11:04, Thomas Lange <la...@informatik.uni-koeln.de> wrote: > > After building the basefile for Ubuntu 18.04 LTS aka Bionic, my first > tests look fine.
