    With Ubuntu 17.10 switching to using Netplan as the default network configuration method (https:/ /insights. ubuntu. com/2017/ 07/10/netplan-by-default-in-17-10/), more and more users will start migrating over to Netplan. This is good news, as Netplan is a nice abstraction. The only solution so far has been to comment out all but one wifi network (in wpa-supplicant), run ifup wlan0 and then reboot the rig. Then the person can go back in with edit-wifi and remove the hashtags for the other networks. The first person did this fix and the rig worked for a week or so before the error reappeared.
