The same problem occurs when the hdd is automatically decrypted with clevis and a tang server. The script /usr/share/initramfs- tools/scripts/local-bottom/clevis tries to deactivate the network interface again after it got the secret to decrypt the disk from the tang server:
... for iface in /sys/class/net/*; do if [ -e "$iface" ]; then iface=$(basename "$iface") ip link set dev "$iface" down ip addr flush dev "$iface" ip route flush dev "$iface" fi done The presence of /run/net-*.conf and /run/netplan/*.yaml leads to the interface beeing managed by systemd-networkd instad of NetworkManager here, too. Instead of implementing removal of the files in dropbear an clevis, maybe there is a single place to serve both, dropbear and clevis? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1813394 Title: DROPBEAR_IFDOWN=* takes interface down but leaves netplan config To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/clevis/+bug/1813394/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
