Ubuntu – Very slow boot time ubuntu – A start job is running for Raise network interfaces

bootnetworking

I am running ubuntu 16.04 and since few days it takes around 5 min to boot up. I looked related questions but I could not find how to troubleshoot my problem. When I run:

systemd-analyze blame

I get this utput: 

5min 2.242s networking.service
     21.128s vboxdrv.service
      5.637s NetworkManager-wait-online.service
      3.436s apt-daily.service
       592ms dev-sda1.device
       462ms lightdm.service
       442ms plymouth-quit-wait.service
       389ms libvirt-guests.service

So I guess networking.service is causing the problem. Can somebody help me to fix that? thank you

Maybe it is a workaround but I could reduce the boot up time following the answer at https://ubuntuforums.org/showthread.php?t=2323253, i.e. by editing the file:

sudo vim /etc/systemd/system/network-online.targets.wants/networking.service

And changing the following line at the end of the file:

TimeoutStartSec=5min

to:

TimeoutStartSec=30sec

I have then rebooted the system and it works fine.

If you dont want to reboot the system again, just reboot the daemon by:

sudo systemctl daemon-reload
