[Bug 1396536] Re: lxc_start - Exec format error - failed to exec /sbin/init
We've not seen any other issue like this in the past 5 years, users usually know to pick something that they can actually run or know that they'll need to setup emulation. The error reported as weird as it is, is the expected behavior from the kernel when asked to run a foreign architecture binary, so no obvious bug to fix here nor really a way for LXC to distinguish that case from an actual permission issue. ** Changed in: lxc (Ubuntu) Status: Triaged => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1396536 Title: lxc_start - Exec format error - failed to exec /sbin/init To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1396536/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I agree it'd be nice for the download template to be clever and filter its output. However the fact that it's very very difficult to know what your CPU is actually capable of running (especially for arm64, armel, armhf and powerpc, powerpc64 and ppc64el) and the name for the architectures changes between distributions too. So for now, we expect our users to know what architecture their CPU is capable of running and then select something which has a chance to work.

[Bug 1396536] Re: lxc_start - Exec format error - failed to exec /sbin/init
No my arch is amd64, that's why I specified "-a armhf". I know about qemu (I wasn't sure whether to use static or binfmt), but errors should be meaningful, instead it seems as if lxc is working fine, but in fact it's not. Obviously it's not a matter of permissions, so the error is wrong. The image I used is downloaded from debian.org, so I didn't prepare it myself. Either non-armhf hosts shouldn't list armhf images or should warn (maybe in documentation, if not in code) that those aren't usable without additional packages. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1396536 Title: lxc_start - Exec format error - failed to exec /sbin/init To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1396536/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

In case it wasn't clear I followed instructions for "basic privileged usage". not user namespaces. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1396536 Title: lxc_start - Exec format error - failed to exec /sbin/init To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1396536/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
