Understanding the architecture of your system is crucial when it comes to installing packages. If you’ve ever tried to install an ‘arm64’ package on an ‘amd64’ system, you’ve likely encountered an error. This article aims to explain why this issue arises and how to resolve it.
When trying to install ‘arm64’ packages on an ‘amd64’ system, you will encounter an error because the ‘arm64’ package is not compatible with the ‘amd64’ system. However, you can enable multiarch support to install ‘arm64’ packages on your ‘amd64’ system. This allows you to install packages from different architectures on the same system.
Understanding System Architecture
Before delving into the problem, it’s important to understand what ‘arm64’ and ‘amd64’ mean. These are names for specific types of system architectures. ‘amd64’ is a 64-bit architecture developed by AMD, which is widely used in desktop and laptop computers. On the other hand, ‘arm64’, also known as ‘AArch64’, is a 64-bit architecture developed by ARM, commonly used in mobile devices and servers.
The packages you install on your system need to be built specifically for your system’s architecture. If you try to install a package built for a different architecture, you’ll encounter compatibility issues.
The Issue: Installing ‘arm64’ Packages on an ‘amd64’ System
If you try to install an ‘arm64’ package on an ‘amd64’ system, you’ll likely see an error message like “package architecture (arm64) does not match system (amd64)”. This error arises because the ‘arm64’ package is not compatible with the ‘amd64’ system.
However, you might notice that ‘armhf’ packages can be installed on ‘amd64’ systems. This is because ‘armhf’ is a different architecture that is compatible with ‘amd64’ systems.
The Solution: Enabling Multiarch Support
To install ‘arm64’ packages on an ‘amd64’ system, you need to enable multiarch support. Multiarch allows you to install packages from different architectures on the same system.
Here’s how to enable multiarch support:
- Open a terminal. You can do this by searching for ‘terminal’ in your system’s application menu or by using the keyboard shortcut
- Add the ‘arm64’ architecture by running the following command:
In this command,
sudo dpkg --add-architecture arm64
sudogives you superuser privileges,
dpkgis the package management command, and
--add-architectureis the option to add a new architecture.
- Update your package lists with the following command:
sudo apt-get update
apt-getis the Advanced Packaging Tool, and
updateis the command to refresh your package lists.
- You can now install ‘arm64’ packages using the ‘:arm64’ suffix. For instance, to install the ‘gcc-6-base’ package, you would run:
In this command,
sudo apt-get install gcc-6-base:arm64
installis the command to install a package, and
gcc-6-base:arm64is the name of the package with the architecture suffix.
Potential Issues and Limitations
Enabling multiarch support should allow you to install ‘arm64’ packages on your ‘amd64’ system. However, this doesn’t guarantee that all ‘arm64’ packages will work correctly. Some packages may have dependencies or requirements that aren’t compatible with ‘amd64’ systems.
If you encounter any errors during the installation process, ensure that you have the correct package name and that the package is available for the ‘arm64’ architecture. You can check this by visiting the package’s website or consulting its documentation.
In conclusion, while system architecture can pose a challenge when installing packages, solutions like multiarch support can help overcome these issues. Understanding your system’s architecture and the architecture of the packages you’re trying to install is key to resolving compatibility problems.
No, ‘amd64’ packages are specifically built for ‘amd64’ systems and are not compatible with ‘arm64’ systems.
No, ‘arm64’ packages are built for the ‘arm64’ architecture, while ‘armhf’ packages are built for the ‘armhf’ architecture. These architectures are not compatible with each other.
Yes, you can enable multiarch support to install packages from different architectures on the same system. However, not all packages from different architectures may work correctly, as they may have dependencies or requirements that are not compatible with your system’s architecture.
You can check the architecture of your system by opening a terminal and running the command
uname -m. It will display the machine architecture, which will indicate whether it is ‘amd64’, ‘arm64’, or something else.
You can find ‘arm64’ packages compatible with your system by visiting the official package repositories or the websites of the software you want to install. Make sure to check the documentation or support resources for the specific package to ensure compatibility with your system’s architecture.
