dmesg: read kernel buffer failed: Operation not permitted
Это только у меня такое нововведение?
Спасибо.

linux-latest (76) unstable; urgency=medium
* From Linux 4.8, several changes have been made in the kernel
configuration to 'harden' the system, i.e. to mitigate security bugs.
Some changes may cause legitimate applications to fail, and can be
reverted by run-time configuration:
- On 64-bit PCs (amd64), the old 'virtual syscall' interface is
disabled. This breaks (e)glibc 2.13 and earlier. To re-enable it,
set the kernel parameter: vsyscall=emulate
- On most architectures, the /dev/mem device can no longer be used to
access devices that also have a kernel driver. This breaks dosemu
and some old user-space graphics drivers. To allow this, set the
kernel parameter: iomem=relaxed
- The kernel log is no longer readable by unprivileged users. To
allow this, set the sysctl: kernel.dmesg_restrict=0
