System information

OS & Version: Linux Ubuntu 16.04

I get this Error on my geth...

And spamming very much time... how can i fix it?
I find a tutorial for windows but not for Ubuntu with only terminal

You can use timedatectl set-ntp true to enable NTP on Ubuntu.

[Marow]

I tried timedatectl set-ntp true but there is doing nothing...

if i check timedatectlagain

Network time on: yes
NTP synchronized: no
RTC in local TZ: no

[karalabe]

If you open up the "Time and Date" settings app (just search for it from the start menu), there will be a radio button to set the time Automatically from the Internet. That should do it.

[Marow]

I have only Terminal Ubuntu Server.

In theory, the NTP synchronized: no should change to yes after a while. If that doesn't happen something is wrong with NTP on the machine.

I have the same issue. The node has been running for several months and stopped with the message several days ago. I had the same issue when I first ran the node but I didn't remember what was the solution.

[dannywillems]

sudo apt-get update
sudo apt-get install ntp
sudo service ntp start

seems to resolve the issue.

[karalabe]

Sweet :) Closing then.

[dannywillems]

@karalabe I don't know if it fixes @Marow issue... Maybe it's not the same solution.

[karalabe]

Aaah, didn't see that there are two different people with this issue :D

[apa7]

Ubuntu12 can't fix it

[sourav1547]

sudo apt-get update
sudo apt-get install ntp
sudo service ntp start

I followed the above and it worked in few machines. The approach in the following link worked for all.

Seems to be solved, closing again
