I can't reach my Linode!
After migrating my Linode to the Tokyo 2 datacenter, I'm unable to ping my Linode. I can log in through Lish and I see the following message:
[FAILED] Failed to start Raise network interfaces.
See 'systemctl status networking.service' for details.
What should I do?
Running the following commands from your Linode will give you some more information about the problem:
systemctl status networking.service -l
sudo ifdown -a && sudo ifup -a
Recently, we’ve seen a large number of these issues caused by a broken sendmail update. If you run those commands and see output similar to the following, it’s likely you’re running into this issue as well:
/etc/network/if-up.d/sendmail: 44: .: Can't open /usr/share/sendmail/dynamic
run-parts: /etc/network/if-up.d/sendmail exited with return code 2
The sendmail issue can usually be resolved by running the following two commands:
sudo mv /etc/network/if-up.d/sendmail ~
ifdown -a && ifup -a
