The gist of this bug is that a file sitting in /posix.ini for example, copied there by ucf from /usr/share/php7.2-common/common/posix.ini, cannot be read by non-root users despite its permission bits being 0644. chmodding 0644 on top of the file fixes this, also rebooting the lxc container solves it as well. After downgrading the same test node to 4.4.0-157 and re-running the same tests, the broken behavior does not occur. Please see the attachments for the exact commands used to reproduce this. --- AlsaDevices: Error: command ['ls', '-l', '/dev/snd/'] failed with exit code 2: ls: cannot access '/dev/snd/': No such file or directory AplayDevices: Error: [Errno 2] No such file or directory ApportVersion: 2.20.1-0ubuntu2.19 Architecture: amd64 ArecordDevices: Error: [Errno 2] No such file or directory CRDA: N/A DistroRelease: Ubuntu 16.04 IwConfig: Error: [Errno 2] No such file or directory Lspci: Error: [Errno 2] No such file or directory Lsusb: Error: [Errno 2] No such file or directory MachineType: OpenStack Foundation OpenStack Nova Package: linux (not installed) PciMultimedia: ProcEnviron: TERM=screen PATH=(custom, no user) LANG=C.UTF-8 SHELL=/bin/bash ProcFB: ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.4.0-159-generic root=LABEL=cloudimg-rootfs ro console=tty0 console=ttyS0,115200 no_timer_check nofb nomodeset vga=normal ProcVersionSignature: Ubuntu 4.4.0-159.187-generic 4.4.185 RelatedPackageVersions: linux-restricted-modules-4.4.0-159-generic N/A linux-backports-modules-4.4.0-159-generic N/A linux-firmware N/A RfKill: Error: [Errno 2] No such file or directory Tags: xenial xenial UdevDb: Error: [Errno 2] No such file or directory Uname: Linux 4.4.0-159-generic x86_64 UnreportableReason: The report belongs to a package that is not installed.
