I booted into recovery to see if there the network was working again. It is a bug of Networkmanager. Probably the username 'power' doesn't affect the connection.
Solution: sudo -H gedit /etc/NetworkManager/NetworkManager.conf At the bottom of this file, copy and paste the following: [device] wifi.scan-rand-mac-address=no Restart the networkmanager sudo service network-manager restart -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1682637 Title: during recovery mode, enable network failed due to /etc/resolv.conf not being present Status in network-manager package in Ubuntu: Confirmed Bug description: Something went wrong that required me to boot to recovery mode via grub. The important part here, is that while I got as far as the recovery screen asking to "Enable Networking" and other options fsck filesystems, drop to root shell, etc. and selected "Enable Networking": the result was: grep: /etc/resolv.conf: No such File or directory. Unknown group "power" in message bus configuration file. (Networking did not enable, leaving me stranded at root shell without network which would have made adding/removing packages to troubleshoot easier) Ubuntu: zesty 17.04 Linux: Linux Hedy 4.10.0-19-generic #21-Ubuntu SMP Thu Apr 6 17:04:57 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux network-manager: 1.4.4-1ubuntu3 ProblemType: Bug DistroRelease: Ubuntu 17.04 Package: network-manager 1.4.4-1ubuntu3 ProcVersionSignature: Ubuntu 4.10.0-19.21-generic 4.10.8 Uname: Linux 4.10.0-19-generic x86_64 ApportVersion: 2.20.4-0ubuntu4 Architecture: amd64 CurrentDesktop: XFCE Date: Thu Apr 13 16:40:19 2017 EcryptfsInUse: Yes IfupdownConfig: # interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback InstallationDate: Installed on 2014-07-09 (1009 days ago) InstallationMedia: Ubuntu-GNOME 14.10 "Utopic Unicorn" - Alpha amd64 (20140708) IpRoute: default via 192.168.250.1 dev wlan1 proto static metric 600 10.0.3.0/24 dev lxcbr0 proto kernel scope link src 10.0.3.1 linkdown 169.254.0.0/16 dev lxcbr0 scope link metric 1000 linkdown 192.168.250.0/24 dev wlan1 proto kernel scope link src 192.168.250.3 metric 600 NetworkManager.conf: [main] plugins=ifupdown,keyfile [ifupdown] managed=false NetworkManager.state: [main] NetworkingEnabled=true WirelessEnabled=true WWANEnabled=false SourcePackage: network-manager UpgradeStatus: Upgraded to zesty on 2017-04-13 (0 days ago) nmcli-dev: DEVICE TYPE STATE DBUS-PATH CONNECTION CON-UUID CON-PATH lxcbr0 bridge connected /org/freedesktop/NetworkManager/Devices/3 lxcbr0 46595dd8-757b-4d93-ade3-c066f72d9e2e /org/freedesktop/NetworkManager/ActiveConnection/0 wlan1 wifi connected /org/freedesktop/NetworkManager/Devices/2 Brisbane House 2b25e748-f9c5-4c84-9fe6-0f64071fcf0b /org/freedesktop/NetworkManager/ActiveConnection/1 eth1 ethernet unavailable /org/freedesktop/NetworkManager/Devices/1 -- -- -- lo loopback unmanaged /org/freedesktop/NetworkManager/Devices/0 -- -- -- nmcli-nm: RUNNING VERSION STATE STARTUP CONNECTIVITY NETWORKING WIFI-HW WIFI WWAN-HW WWAN running 1.4.4 connected started full enabled enabled enabled enabled disabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1682637/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
