How To Fix ‘A Start Job is Running for the Raise Network’ Error in Ubuntu Server 16.04 LTS

In this article, we will discuss how to fix the “A start job is running for the raise network” error in Ubuntu Server 16.04 LTS. This error usually occurs during startup and can be quite frustrating. However, with the right steps, it can be resolved.

Understanding the Error

The “A start job is running for the raise network” error is typically associated with the network service in Ubuntu. It occurs when the system is unable to raise the network within a specified time limit. This can be due to various reasons such as incorrect network interface configuration or problems with the networking service itself.

Solution 1: Reduce Timeout for Networking Service

One of the easiest ways to fix this error is by reducing the timeout for the networking service. By default, the timeout is set to a high value, which can cause the system to hang if the network service is unable to start within this time limit.

Steps:

1. Open Terminal: You can do this by pressing Ctrl + Alt + T.
2. Create a new directory for systemd configuration: Systemd is the system and service manager for Linux. It is responsible for initializing the system. Use the following command to create a new directory for systemd configuration:

sudo mkdir -p /etc/systemd/system/networking.service.d/

The -p option in mkdir command is used to create parent directories as needed.

3. Create a configuration file for the networking service: Use the following command to create a new configuration file:

sudo bash -c 'echo -e "[Service]\nTimeoutStartSec=20sec" > /etc/systemd/system/networking.service.d/timeout.conf'

This command uses bash -c to run the echo command as a string. The -e option in echo enables interpretation of backslash escapes. TimeoutStartSec is a systemd directive that sets the timeout for starting the service.

4. Reload systemd configuration: After making changes to the systemd configuration, you need to reload it. Use the following command to reload the systemd configuration:

sudo systemctl daemon-reload

The systemctl command is used to control the systemd system and service manager. daemon-reload is an option that reloads the manager configuration.

Solution 2: Modify Network Interface Configuration

Another way to fix this error is by modifying the network interface configuration. This involves changing the way the network interfaces are brought up during startup.

Steps:

1. Open the network interface configuration file: Use the following command to open the network interface configuration file in a text editor:

sudo nano /etc/network/interfaces

2. Modify the configuration for the network interfaces: Change auto to allow-hotplug for the network interfaces. For example, change:

auto eno1
iface eno1 inet dhcp

to:

allow-hotplug eno1
iface eno1 inet dhcp

allow-hotplug enables the interface when a hotplug event is detected, while auto brings up the interface at boot time.

3. Save the file and exit the text editor: Press Ctrl + X to exit, then press Y to save the changes, and finally press Enter to confirm the filename.

After making these changes, reboot your system and check if the error has been resolved. If not, you can try the alternative method described in the next section.

Solution 3: Modify Network Interface Configuration (Alternative Method)

This method involves setting a specific configuration for each interface in the network interface configuration file.

Steps:

1. Open the network interface configuration file: Use the following command to open the network interface configuration file in a text editor:

sudo nano /etc/network/interfaces

2. Set the following text for each interface in the file:

auto lo
iface lo inet loopback
auto eth0
iface eth0 inet dhcp
auto wlan0
iface wlan0 inet dhcp

3. Save the file and reboot your system: Press Ctrl + X to exit, then press Y to save the changes, and finally press Enter to confirm the filename.

After rebooting your system, the error should be resolved.

Conclusion

In this article, we discussed three solutions to fix the “A start job is running for the raise network” error in Ubuntu Server 16.04 LTS. These solutions involve reducing the timeout for the networking service and modifying the network interface configuration. It’s important to note that these solutions may vary depending on your specific network setup. Always remember to backup any configuration files before making changes.
