Arch Linux

Description:

After pacman update, the network of my Odroid U2 stopped working.
The reason is that systemd-networkd cannot get an ip address from my DHCP server.

However, the ip address can be obtained if run dhcpcd eth0 manually,
but still cannot solve the domain names, e.g. ping wwww.google.com is not working

Additional info:

* package version(s):
last update is done around 2020-Mar-11 3:00am US Estern Time

* config and/or log files etc.
