I repeat myself: Flexibility for flexibility's sake is not a goal of Ubuntu. That you have disabled a base component of Ubuntu and the resulting system does not function as you expect is not a valid bug report against Ubuntu. If there are scenarios where it is not appropriate to run resolved, then we should absolutely evaluate those and determine how they should be supported in Ubuntu. However, they must be evaluated on their own merits, which means that the technical details must be presented for consideration. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1745463 Title: Disabling systemd-resolved breaks dhclient resolvconf integration Status in resolvconf package in Ubuntu: Expired Status in systemd package in Ubuntu: New Bug description: To reproduce, mask resolved: sudo systemctl mask systemd-resolved.service ...then disable network-manager for ifupdown interfaces: $cat /etc/NetworkManager/NetworkManager.conf [main] plugins=ifupdown,keyfile dns=default rc-manager=resolvconf [ifupdown] managed=false [device] wifi.scan-rand-mac-address=no ...and reboot. You'll note that resolvconf integration with dhclient is now broken. Interfaces listed in /etc/network/interfaces or /etc/network/interfaces.d/* will not provide DNS configuration in /etc/resolv.conf and /run/resolvconf/interfaces/. This is because /etc/dhcp/dhclient-enter-hooks.d/resolvconf defines "make_resolv_conf()" as a valid function for the BOUND case, but /etc/dhcp/dhclient-enter-hooks.d/resolved undefines it (who's nasty now, eh?) even though resolved is masked. The file existence check in the beginning of /etc/dhcp/dhclient-enter- hooks.d/resolved should be more thorough, i.e. it should ensure that resolved is enabled, rather than simply look for the existence of /lib/systemd/systemd-resolved. This works for me: -if [ -x /lib/systemd/systemd-resolved ] ; then +if [ -x /lib/systemd/systemd-resolved ] && systemctl -q is-enabled systemd-resolved ; then Arguably, /etc/dhcp/dhclient-enter-hooks.d/resolvconf should implement a similar check, looking for /run/resolvconf/enable-updates as a condition for meddling with DNS settings. If desired, I'll file a separate bug for that package.
