Temporary failure in name resolution Ubuntu on 20.04.1 LTS

Temporary failure in name resolution Ubuntu on 20.04.1 LTS

Temporary failure in name resolution Ubuntu on 20.04.1 LTS - Hello everyone, on this occasion, I will share my experience about the problem I faced, when my server using the Ubuntu 20.04.1 LTS linux operating system could not ping google.com.

ping google.com Temporary failure in name resolution

Issue

with the log error displayed is ping: google.com: Temporary failure in name resolution

Cause

Third party programs must not access this file directly, but only through the symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a different way, replace this symlink by a static file or a different symlink.

Resolution

I only use an easy solution, which is to backup the original file first and make a manual resolv.conf directed to the google ip.

Disable systemd-resolved

# systemctl disable systemd-resolved.service

Stop Service systemd-resolved

# systemctl stop systemd-resolved.service

Move File resolv.conf to resolv.conf.ori

# mv resolv.conf resolv.conf.ori

Make file resolv.conf manual

# vi resolv.conf

nameserver 8.8.8.8

save & quit

Trying

# ping 8.8.8.8
# ping google.com

successful ping to google.com
