Ubuntu apt-get install, error with org.freedesktop.systemd1.service

Had an issue trying to recover from a failed upgrade.  Apt would complain about dependencies, suggested running apt-get install -f.

Running apt-get install -f would still fail.  It showed a conflict with the systemd1.service, ended up renaming the file with the following command

sudo mv /usr/share/dbus-1/system-service/org.freedesktop.systemd1.service{,bak}

and reran

sudo apt-get install -f

after that I was able to rerun the upgrade and finish

sudo apt-get upgrade

Connect to WiFi network via command line

Easiest way is to use the Network Manager nmtui tool


It gives you a “command line GUI” to search and select your preferred WiFi network.

Alternate way is to use the iw tools.

Scan for available WiFi networks

iwlist scan

Connect with iwconfig, replace WiFiName with your WiFi name.  Note this only works with open networks.

iwconfig wlan0 essid WiFiName

You’ll need to get an address now, so run


Check if your DNS is working.  If not, as a “hack” manually add it to /etc/resolv.conf and restart the networking service.

sudo echo "nameserver" >> /etc/resolv.conf
sudo service networking restart

Your not supposed to manually put the nameservers in resolv.conf.  But it works in a pinch.
