Few changes to 18.04

  • Network order has been somewhat fixed, you can use the network manager to set IP address/gateway/etc
  • SDDM is now an issue (formally KDM) - it loads before ubuntu has a chance to get NIS users. Additionally, it logs out users after a couple of minutes of use - can't figure why (possible graphics issue? not being able to immediately do something with users passwd/profile?). It is definitely not a power saving problem.
    • Fix for this is to use lightdm

sudo apt-get install lightdm-gtk-greeter lightdm

  • IS had changed some gateway settings, here's the new set of addresses to use for interfaces;
auto enp*s*
iface enp*s* inet static
address 128.243.74.***
  • To get a local (lab) network working (with devices that can set their own IP and point to as the gateway), add this to interfaces;
auto enp*s*
iface enp*s* inet static
  • Restart networking using sudo systemctl restart networking
  • In some cases network doesn't work with this setting, use netplan instead: make sure /etc/netplan/01-network-manager-all.yaml is like this:
        version: 2
        renderer: networkd
                        dhcp4: no
                        addresses: [128.243.74.***/24]
                                    addresses: [,,]

                      addresses: [192.168.74.xx/24]

where enp*s*1 for internet and enp*s*2 for a local network. And run sudo netplan apply. Use space instead of tab for each line, and has to be at the exact position, or sudo netplan apply would return error.

  • Make sure you do sudo apt-get install tcsh openssh-client openssh-server before asking help from the software fairy!
  • If you can not see your home directory, do
 systemctl add-wants rpcbind.service

which simply mean rpcbind must start first.
