For example, verify you are not using a 32bit CD instead of a 64bit CD. You need a 64bit kernel to run 64bit code, so check your architecture. Assuming you mounted your system to be chrooted in /media/sda1, to determine the architecture you can: ls /media/sda1/* if you see lib64 in the output, it's probably a 64bit system share|improve this answer edited Jul 11 '11 at 9:36 4levels 1135 answered Nov 21 '10 at 11:30 Grand Oxymore 3491510 It is but still cannot chroot –Starx Mar 29 '12 at 10:03 add a comment| up vote 1 down vote The error means that your jail (/mnt/temp) does not contain a bash shell, or does not contain the libraries required to run the bash shell. If you created your jail using something like this: debootstrap --variant=buildd --arch i386 lucid /mnt/temp \ http://archive.ubuntu.com/ubuntu/ You probably meant to do this instead: debootstrap --variant=minbase --arch i386 lucid /mnt/temp \ http://archive.ubuntu.com/ubuntu/ However, as a technical answer to your problem, try: cp -r /bin /lib /mnt/temp This should allow you to chroot successfully, at which point you can do other things. There are about a million things wrong with doing that though, and almost certainly you do not want to do that. Use minbase when you create your jail, or instal

Cannot Execute Exec Format Error In Linux

I've seen that it's possible to do using static qemu by copying the binary into the chroot system: $ cp /usr/bin/qemu-arm archarm-chroot/usr/bin But despite this I always get the following error: chroot: failed to run command ‘/bin/bash’: Exec format error I know this means that the architectures differ.

An example for configuring binfmt_misc can be found at svn.kju-app.org/trunk/qemu/qemu/qemu-binfmt-conf.sh –Ulrich Dangel Jun 28 '12 at 23:00 Qemu static packages don't appear to be in the Arch repositories. –Jivings Jun 28 '12 at 23:04 1 Sorry i don't use arch, but you should probably be able to build a static qemu package by adding -static to the linker options –Ulrich Dangel Jun 28 '12 at 23:07 add a comment| 6 Answers 6 active oldest votes up vote 11 down vote accepted You cannot chroot into different architecture. By chrooting, you are executing the binaries (from the chroot) on your architecture. Executing ARM binaries on x86 (and x86_64 in that matter) would lead to "Exec format error". If you want to run binaries from different architecture you will need an Emulator. Qemu is a good candidate for this, but you will need to learn how to use it. This would involve creating RootFS and compiling a kernel for ARM. You will need a toolchain for compiling ARM binaries (and kernel) perhaps. One thing is for sure: Forget the chroot method, you cannot run binaries compiled for ARM on x86 (x86_64). Edit: After the small talk

Analysis The error Exec format error means that the binary being executed exec format error is made for a different architecture than the environment currently booted. It usually occurs when the system has been booted on a 32-bit system when a 64-bit environment is trying to load. Resolution Reboot the live environment and choose the correct architecture (most LiveCDs support a 64-bit kernel as well as a 32-bit option, although it is not booted by default). Look for entries labeled gentoo64 or linux64 if trying to boot a 64-bit system.
