Does “sudo apt list –upgradeable” include kernel updates?

Ubuntu 11

In the world of Linux, it’s essential to keep your system updated with the latest software and security patches. One of the most crucial components to update is the Linux kernel. But does the command sudo apt list --upgradeable include kernel updates? Let’s delve into the details.

Quick Answer

Yes, running sudo apt list --upgradeable does include kernel updates. However, the actual kernel packages may not appear in the output. Instead, you’ll see kernel metapackages that indicate a new version of the kernel is available. For a more comprehensive view, you can use sudo apt -s upgrade to simulate the upgrade process and see a detailed list of all packages, including the kernel packages.

Understanding the Command

Before we answer the question, let’s first understand the command. sudo apt list --upgradeable is a command that lists all packages in your system that can be upgraded. Here’s a breakdown of the command:

  • sudo: This is a prefix that gives you administrative privileges. It stands for “SuperUser DO”. Without it, you might not be able to perform certain tasks.
  • apt: This is the package handling utility in Ubuntu. It stands for “Advanced Package Tool”.
  • list: This is an argument to apt that lists packages based on certain criteria.
  • --upgradeable: This is an option that tells apt list to show only packages that can be upgraded.

Does It Include Kernel Updates?

Yes, running sudo apt list --upgradeable does include kernel updates. However, it’s important to note that the actual kernel packages (e.g., linux-image-4.4.0-something) might not appear in the output. Instead, you’ll see kernel metapackages (e.g., linux-image-generic) that declare the kernel packages as dependencies. These metapackages indicate that a new version of the kernel is available.

A More Comprehensive View

For a more detailed view of what will be installed or upgraded, you can run sudo apt -s upgrade. This command simulates the upgrade process and provides a comprehensive list of the packages that will be installed or upgraded, including the kernel packages.

Here, -s is an option that tells apt upgrade to simulate an operation. It shows what would happen, but doesn’t actually change the system.

Important Notes

The behavior of apt list --upgradeable can vary depending on the specific situation. In most cases, kernel updates are provided as new packages rather than new versions of existing packages. This allows you to keep your old kernels for a while in case the update causes any issues.

However, if there are bug fixes or updates that do not change the kernel itself, they may be provided as updates to the existing kernel package.

Conclusion

In conclusion, running sudo apt list --upgradeable can give you an indication of available kernel updates, but for a more comprehensive view, it is recommended to use sudo apt -s upgrade to simulate the upgrade process. This will provide you with a detailed list of all packages that are due for an upgrade, including the kernel packages.

Remember, keeping your system updated is crucial for its performance and security. Regularly check for updates and apply them to ensure your system is at its best.

How do I update the Linux kernel?

To update the Linux kernel, you can use the sudo apt upgrade command. This command will update all packages, including the kernel packages, to their latest versions.

Can I update the kernel without updating other packages?

No, when you update the kernel using sudo apt upgrade, it will update all packages on your system to their latest versions. If you only want to update the kernel, you would need to use a different method, such as manually downloading and installing the kernel package.

How often should I update the kernel?

It is recommended to update the kernel whenever new updates are available. Kernel updates often include important security patches and bug fixes, so keeping your kernel up to date is crucial for system stability and security.

Can I revert to an older kernel version if the update causes issues?

Yes, you can revert to an older kernel version if the update causes issues. During the update process, the old kernel packages are usually kept on your system. You can select the older kernel version from the boot menu when you start your computer.

How can I check the current version of the Linux kernel?

To check the current version of the Linux kernel, you can use the uname -r command in the terminal. This will display the kernel version number.

Are kernel updates automatic?

No, kernel updates are not automatic by default. You need to manually initiate the update process using the appropriate command, such as sudo apt upgrade. However, you can set up automatic updates for all packages, including the kernel, by configuring the package management system or using a tool like unattended-upgrades.
