Understanding the Error Message
When you see “A start job is running for Raise network interfaces,” it means there’s a delay in turning on the network interfaces during startup4. This delay can happen for many reasons, like wrong setup files or missing parts. It’s key to find out why to fix the problem.
At times, the error comes from old commands still being used. Before Ubuntu 18.04, ifup/ifdown were outdated, but they’re still in Ubuntu 20.04’s networking files4. Updating your network settings to newer methods is a good idea.
To fix this error, it’s vital to know if it’s a DNS or network issue. Try using the ping command to check if you can connect to both local and public IPs4. If you can ping, your network card is likely working fine, helping you pinpoint the problem.
Fixing DNS problems can also solve the error. This might mean turning off resolvconf and systemd-resolved, or editing /etc/resolv.conf manually4. Adding nameservers can also help with DNS lookup4.
It’s also good to know how to read DNS error messages. Learning about these and basic IPv4 networking can help you fix the issue4.
Checking the system’s drivers with commands like sudo lshw -C network is also a good step4. This can show if hardware or drivers are causing problems. Make sure only one NIC is set up on the same network4.
By understanding the error and following these steps, you can fix the delay in activating network interfaces. This leads to better network setup and system performance45.
Checking the Interface Configuration File
When you see a “start job” error, start by looking at the network interfaceconfiguration file. This file is usually found at
/etc/network/interfaces
. It tells us about the network interfaces and how to turn them on. Make sure it’s set up right and error-free.
This file is key for setting up networks on Ubuntu and other Linux systems. It tells the system how to set up networks when it boots or manually. You can look at this file using a text editor or the
cat
command in the terminal.
In the file, you might see names like
enp0s8
or
ensXX
. These names help Ubuntu identify and keep track of network interfaces. Knowing these names helps you figure out which interfaces are causing the error.
The file might suggest ways to fix network interface problems. These tips could include updating settings, restarting your virtual machine (VM), or restarting network services. Users also share tips on adjusting network advanced options to solve certain problems.
Also, the file might mention closing Windows services like VMware NAT Service and VMnetDHCP. These services can sometimes mess with your network in a virtual setup.
When fixing the issue, be careful with the interface configuration file. A small mistake can cause more problems. Always back up the file before making any changes.
In summary, checking the interface configuration file is crucial for solving “start job” errors with network interfaces. The stats6 show how often these questions come up and the help users get. It shows the value of knowing how to manage Ubuntu networks, updating settings, restarting VMs, and looking at network advanced options. By fixing the file right, you can fix network issues and keep your network running smoothly.

Checking the Init Info for Network Interfaces
Often, the “start job” error happens because of missing init info for network interfaces. This issue arises if interfaces aren’t set up right or if some dependencies are missing12.
When network interfaces aren’t set up correctly, it can mess up the boot process. This leads to the error “A start job is running for LSB: Raise network interfaces.” This error happens about once in every 50 boots12.
To fix this, make sure the init info for network interfaces is there. Check that interfaces are configured well and all needed dependencies are installed. This way, we avoid the “start job” error and ensure network interfaces activate smoothly during boot12.
Missing init info can come from system updates, constant changes to the interfaces file, or DNS changes. These actions can cause problems that stop network interfaces from initializing right12.
One good way to fix this error is to not use a network manager and set a fixed IP manually. This stops any conflicts from the network manager and gives us more control over starting up12.
Also, making the Maximum Transmission Unit (MTU) better and using unbound for DNS can make network interfaces more stable and fast. These steps can fix network issues that cause the “start job” error12.
Summary:
Missing init info for network interfaces can cause the “start job” error during boot cycles12.
Common causes of this error include system upgrades or updates, modifications to the interfaces file, and changes to DNS parameters12.
Avoiding network managers and configuring fixed IPs can help eliminate conflicts and ensure proper initialization12.
Optimizing the MTU and utilizing unbound can improve network interface stability and performance12.
By checking and making sure the init info for network interfaces is set up right, you can fix the “start job” error. This lets network interfaces activate smoothly during the boot process.
Updating and Configuring Networking Services
Sometimes, the “start job” error can be fixed by updating and setting up your system’s networking services. Make sure NetworkManager and ModemManager are turned on and working right. Regular updates and correct settings keep your network stable and avoid the “start job” error.
It’s key to update networking services to run the latest software. This fixes bugs and compatibility problems that might cause errors. With the latest updates, you get new features and better network performance and security.
Configuring networking services means adjusting settings to fit your network needs. This includes setting IP addresses, choosing DNS servers, managing interfaces, and controlling protocols and services.
When updating and setting up networking services, follow best practices for your network. Test and troubleshoot after changes to find and fix any problems.
According to stats13, 82% of networking services are set up to work well. This highlights the need to keep networking services in good shape to avoid network problems.
