linuxlite and ubuntu gnu/linux installs may have automatic unattended upgrades installed and enabled
to check the status of your system
$ aptitude show unattended-upgrades
if installed you can disable it by editing /etc/apt/apt.conf.d/50unattended-upgrades or remove the unattended-upgrades package
# aptitude remove unattended-upgrades # rm /etc/apt/apt.conf.d/50unattended-upgrades # reboot
In past versions of Ubuntu, unattended package upgrades were handled by creating a cron job in /etc/cron.daily responsible for running apt. With 16.04 and the shift to systemd, unattended upgrades are handled by a systemd unit. The new systemd unit has OnCalendar set to 6am and 6pm, along with Persistent set to true. The result is that a full apt-get update && apt-get ugrade will run the first time the box boots, in order to “catch-up” with missed runs.
debian linuxlite 3.8 (ubuntu 16.x) intel microcode
after yoiu have installed this you should see
# journalctl | grep microcode Feb 19 14:57:18 lili kernel: microcode: CPU0 sig=0x40651, pf=0x1, revision=0x1d Feb 19 14:57:18 lili kernel: microcode: Microcode Update Driver: v2.01 <email@example.com>, Peter Oruba
microcode – everything you ever wanted to know
you need forget everything you thought you knew about microcode was in the old Z80 days
run cat /proc/cpuinfo to see what cpu chip & microcode version you have
$ cat /proc/cpuinfo vendor_id : GenuineIntel cpu family : 6 model : 69 model name : Intel(R) Core(TM) i5-4310U CPU @ 2.00GHz microcode : 0x1d flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ss syscall nx pdpe1gb rdtscp lm constant_tsc arch_perfmon nopl xtopology tsc_reliable nonstop_tsc eagerfpu pni pclmulqdq ssse3 fma cx16 pcid sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand hypervisor lahf_lm abm invpcid_single retpoline kaiser fsgsbase tsc_adjust bmi1 avx2 smep bmi2 invpcid xsaveopt arat bugs : cpu_meltdown spectre_v1 spectre_v2 bogomips : 5202.00
have a look at your logs to see if you have any microcode patches
dmesg | grep "microcode" journalctl -b -k | grep "microcode"
you need to enable nonfree deb/rpm repos so you get access to microcode packages
deb http://deb.debian.org/debian jessie main contrib non-free deb http://security.debian.org/ jessie/updates main contrib non-free
then install the microcode package
aptitude update aptitude install amd64-microcode
check your kernels params and reboot
Unfortunately, the license of the microcode update data from AMD and Intel are not compatible with the Debian Free Software Guidelines.
Therefore, microcode update data will be available through the non-free distribution. The new processor microcode update system is available for both non-free Wheezy and non-free Squeeze (through the backports repository).
Meltdown (the vulnerability affecting only Intel chips) cannot be fixed with microcode updates alone and requires changes to core OS functionality, which may reduce performance further.
Spectre (the vulnerability affecting Intel, AMD and ARM chips) may be able to be worked around with microcode updates alone.
