The root cause of the problem [is in libseccomp When][1]. The newer version fixes the problem, but it is not yet available in Debian's stable repos. There are two way to fix this problem:
**Method 1** Start the container with `--privileged`. This bypasses docker's security measures, so it is not recommended. **Method 2** Upgrade libseccomp manually. Dowload version from unstable repos (I tested with 2.4.3-1) [here][2]. Uninstall the current version: `sudo dpkg --force-all -P libseccomp2` Install the new version: `sudo dpkg -i libseccomp2_2.4.3-1+b1_armhf.deb` [1]: https://github.com/moby/moby/issues/40734 [2]: https://packages.debian.org/sid/libseccomp2 ** Bug watch added: github.com/moby/moby/issues #40734 https://github.com/moby/moby/issues/40734 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1890332 Title: apt update fails on docker arm container 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1890332/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
