GitHub is home to over 50 million developers working together to host and review code, manage projects, and build software together. While trying to generate the image on Ubuntu In order to solve this problem, on Ubuntu, one should install the Debian Archive Keyring package: sudo apt install debian-archive-keyring. But that was not enough, after solving that problem it fails later on after a few minutes running with:. To further isolate the issue and work around ityou could try building the image in a Debian chroot, container or VM.
I have tried to run it under a Docker container Debian-based image. I had to run it as privileged and sharing the loopback devices, but still kpartx did not work within the container. Actually, the kpartx command worked when partly when tried manually, e.
Did commit fa47ee9 fix your issue by any chance? I don't know if it is because I restarted my computer just before or if it is your commit I would think the latter that fix it, but it did work today at least no errors are reported. I need to test the build image now. At least I can see it has installed raspi3-firmware version 1. Skip to content. This repository has been archived by the owner. It is now read-only.

Thank you very much for the fix and quick reply, this is much appreciated.Prerequisites You will need: debootstrap; your debootstrap should be recent enough to debootstrap the suite you're interested in one of qemu-arm-static syscall emulation or qemu-system-arm machine emulation e2fsprogs or some mkfs.
Building the Root Filesystem The initial image of the root filesystem can be done manually via "debootstrap", or more easily via the "mk-sbuild" wrapper.
Debian, point at the Debian keyring instead in the debian-archive-keyring package give some progress information only do the first phase of the bootstrapping target the Ubuntu 9.
TODO link to man page Second stage debootstrap with QEMU QEMU sports two types of emulation: syscall emulation: this translates code from one architecture to another, remapping system calls calls to the kernel between the two architectures machine emulation: this emulates a complete computer, including a virtual CPU, a virtual video card, a virtual clock, a virtual SCSI controller etc. QEMU's syscall emulation is much faster than machine emulation, but both are relatively slow when compared to native programs for your computer.
One major drawback of syscall emulation is that it that some syscalls are not emulated, so some programs might now work, also when building programs, these might configure themselve for the features of the kernel they run on instead of what the target architecture actually supports.
For rootfs creation, using syscall emulation is probably fine for core packages, but you might run into issues with higher level ones. Using syscall emulation While qemu-arm can be used to run a single armel binary from the command-line, it's impractical to use it to run a program which will fork and execute other programs.
Also, because qemu-arm itself uses shared libraries and the ld. So the following instructions expect that you're using a static version of qemu-arm "qemu-arm-static"and that your build environment supports the binfmt-misc module, this modules allows running any executable matching some configured pattern with an interpreter of your choice.
Ubuntu You can create a tarball of the rootfs directory, or copy the files into an actual filesystem; see Creating a filesystem from a directory. You might want to do some system configuration before using this rootfs on devices though; see System configuration. You may also re-enter the chroot as above, e. Using machine emulation Install qemu-system-arm you don't need a static version : Ubuntu Create a filesystem image from the rootfs directory; see Creating a filesystem from a directory.
You might want to do some system configuration before using this rootfs on devics though; see System configuration. Next, add to that amount the number in bytes of extra space you want in the filesystem. Partners Support Community Ubuntu.This page contains details about the port of Debian to the bit Arm platform arm64known in some other places as AArch This port was released for the first time with Jessie Debian 8. The port was started in by Arm and Linaro working with the community in commendable fashion long before hardware was available so that there would be something to run when it arrived.
Hardware started to becoming available in Octoberbut access was restricted. Debian was very kindly donated two 8-core APM machines, installed in March running two buildds in Debian-ports.
One was split with xen so we also had an unofficial porterbox. Hardware, emulators and models Arm64 hardware was first available in the form of the iPhone 5 in More hardware including a couple of fairly cheap dev boards became available during and it's also gone into quite a lot of android phones. Affordable Linux build machines became available in It was added to qemu upstream in v2.
See Qemu Rootfs below for details. Arm64 qemu system emulation was added to qemu upstream and is available in Debian with qemu-system-arm 2. There is a non-free, free beer 'Foundation Model' simulator which can be used to run arm64 code, which is available here Much of the work packagers need to worry about is updating autoconf, multiarch and cross-build fixes, with a few actual arm64 changes here and there, and doesn't actually need a model or emulator.
Status last updated: June 1st Official Debian port Initial setup The official archive had the first bootstrap packages installed from debian-ports on 8th August Two Arm-sponsored buildds Juno were installed, configured and started building on 15th August Stretch Arm64 is a first-class release architecture in Stretch, with almost all packages built, and the standard installer working on various machines, and quite likely to work on new ones.
Jessie Arm64 is an official debian release architecture in Jessie.
So nearly everything you expect is in the release. The main things missing are mono and dependencieslibvp8 and thus nodejs ecosystemfsharp, gcgo, rust. A few higher-level apps also didn't make it, such as abiword, and xbmc.
Hardware, emulators and models
It needs a patch to initramfs for Juno. Please check the packages in the 'Build Attempted' section there to see what needs fixing. Many of them are trivial fixes.Contents Example Configuration Step 1: Install packages on the host computer. Step 2: Create a configuration file for schroot. Step 3: Run debootstrap. A chroot can be used for things like: Running a bit Firefox browser or a bit Wine bottle on a bit system.
Trying an older or newer Ubuntu release without reinstalling the operating system. Trying a Debian release or other distribution derived from Debian. Cross compiling and building packages for a different platform like Launchpad or Soyuz does it. Example Configuration In this example, we use a current Ubuntu 9. Step 1: Install packages on the host computer. For example, the debootstrap that is bundled with Jaunty can prepare a Hardy chroot like we are doing here, but the debootstrap that is bundled with Hardy cannot prepare a Jaunty chroot.
If you forget, the command schroot -l will fail with an error, e. Note: for lucid use directory instead of locatione. Otherwise, leave it disabled. Your username on the host system should be here. Additionally, keywords have to start at the beginning of the line. To leave it, type "exit". To be able to run X applications, e. CategoryDevelopment DebootstrapChroot last edited by pargue.

Sign in to your account. Hi, It is not a failure on scripts, but I do know where else to ask, debootstrap second stage always fails with:. W: Failure while unpacking required packages. This will be attempted up to five times. Preparing to unpack Hi thanks for your feedback and thanks for the detailed configuration you used. I will investigative the problem in a couple of days and find a solution :. Hi Ignacio, Few weeks ago I used this configuration file that worked with some errors but the image was OK.
Maybe you can compare with yours. I have noticed that buster was changing very fast and that qemu was not progressing so fast, this may raise temporary problems, I have also chosen a kernel version which was tested on my Debian not the default one.
I am adding many goodies that you may not desire ;- get rid of them. Thanks both for your fast and accurate answers! Finally I have managed to succesfully create an Stretch arm64 image, and I'm playing with It :. I solved it by installing them manually after first login with apt install and dpkg-reconfigure with no problem at all my image was already generated. When I have more time, I'll try to experiment with buster image on a spare SD card and I'll inform you about results.

However, running a dynamically linked executable requires more efforts. To run a dynamically linked executable, a complete user space environment including dynamic linker, shared libraries, etc must be set up. Fortunately, qemu-debootstrap can help us set up an Ubuntu or Debian user space environment. In this post, the instructions to set up an ARM64 Ubuntu environment will be presented. To create an Ubuntu Now, we are in an environment that can run ARM bit binaries. For example, we can check the architecture with:.
In this post, I have covered qemu-user-staticqemu-debootstrap and schroot. These tools significantly boosted my productivity on cross-architecture development. I hope this article is helpful.
Thanks for reading. Introduction to qemu-debootstrap Sat 21 January Tags qemu linux aarch64 arm Prerequisites Three packages are required for this post: debootstrap is a Debian or Ubuntu bootstrap tool. It will download several deb packages and set up a minimal Debian or Ubuntu user space. Don't confuse this package with qemu-user. The static version must be installed because these QEMU executables will be copied into chroot environments.
This package also includes qemu-debootstrapwhich is a wrapper for cross-architecture debootstrap. Besides changing the root directory, schroot will run several hooks before entering and after leaving the chroot so that many functionalities, including network, can work without problems.

If you would like to change the apt repository, specify the URL after the directory name.Once you've got the new Debian system configured to your preference, you can migrate your existing user data if any to it, and keep on rolling.
It's also a clever way for dealing with hardware that otherwise doesn't play friendly with various boot or installation media.
As this is a mostly manual procedure, you should bear in mind that you will need to do a lot of basic configuration of the system yourself, which will also require more knowledge of Debian and of Linux in general than performing a regular installation.
You cannot expect this procedure to result in a system that is identical to a system from a regular installation. You should also keep in mind that this procedure only gives the basic steps to set up a system. Next, create file systems on the partitions. To create an ext2 file system instead, omit -j. Initialize and activate swap substitute the partition number for your intended Debian swap partition :. The mount point name is strictly arbitrary, it is referenced later below.
If you want to have parts of the filesystem e. The utility used by the Debian installer, and recognized as the official way to install a Debian base system, is debootstrap. Install wget and ar if they aren't already on your current system, then download and install debootstrap. Or, you can use the following procedure to install it manually. Make a work folder for extracting the. The debootstrap binary is located in the Debian archive be sure to select the proper file for your architecture.
Download the debootstrap. You will need to have root privileges to install the files. You can substitute any Debian archive mirror for http. Substitute one of the following for ARCH in the debootstrap command: amd64arm64armelarmhfimipsmips64elmipselpowerpcppc64elor sx. If the target architecture is different than the host, you should add the --foreign option. Now you've got a real Debian system, though rather lean, on disk. If the target architecture is different from the host, you will need to first copy qemu-user-static to the new host:.
After chrooting you may need to set the terminal definition to be compatible with the Debian base system, for example:. Depending on the value of TERM, you may have to install the ncurses-term package to get support for it.
If the target architecture is different from the host, you need to finish the multi-stage boot strap:. For the next steps of the installation additional device files may be needed. There are different ways to go about this and which method you should use depends on the host system you are using for the installation, on whether you intend to use a modular kernel or not, and on whether you intend to use dynamic e.
Create these as as needed, for example:. If you didn't use mount -abe sure to mount proc before continuing:. Should this fail, you may be able to mount proc from outside the chroot:.
The following command allows you to set that. Then during boot, each card will be associated with the interface name eth0, eth1, etc. However, you may want to add some additional sources, for example for source packages and security updates:. Make sure to run apt update after you have made changes to the sources list. To configure your locale settings to use a language other than English, install the locales support package and configure it.
Currently the use of UTF-8 locales is recommended.Debugging an ARM64 linux kernel using QEMU
Note that the keyboard cannot be set while in the chroot, but will be configured for the next reboot.
