No DNS after installing pacman

[vistalba]

First I run a ping:

[neeo@NEEO-12345f78 steady]$ sudo ping google.ch

PING google.ch (172.217.168.67) 56(84) bytes of data.
64 bytes from zrh04s15-in-f3.1e100.net (172.217.168.67): icmp_seq=1 ttl=54 time=7.99 ms

rtt min/avg/max/mdev = 7.998/7.998/7.998/0.000 ms

After issuing the command sudo pacman -S --force pacman I get this output:

[neeo@NEEO-12345f78 steady]$ sudo pacman -S --force pacman

:: Proceed with installation? [Y/n]

After pressing y and waiting that the installation finished DNS is not working anymore:

[neeo@NEEO-12345f78 steady]$ sudo ping google.ch
ping: google.ch: Name or service not known

Also a reboot does not solve this issue. When using drill I still get the correct result from my DNS:

[neeo@NEEO-12345f78 ~]$ drill google.ch

Any ideas how to fix this or why this happens?
