Does anybody know why the amd64-microcode package gets installed automatically on systems that use Intel processors during the latest 16.04 updates on May 22, 2018?

Hm. ```apt-cache rdepends amd64-microcode``` suggests that only ```linux-image-oem``` depends on that package. Do you have that installed by any chance? – Martin W May 22 '18 at 19:18

I am using `intel-microcode` since my systems use Intel CPU's. Today though, I saw that along with the new 4.4.0-127 kernel `amd64-microcode` got installed as a new package on two systems. I am using the `linux-generic` kernel. – Stormlord May 22 '18 at 19:55

Isn't that the fix for the meltdown bug that was found in Intel CPUs? – singrium May 22 '18 at 20:04

1@dsstorefile1, No. I can't even find that package in the repos. Only `linux-firmware` is installed. – Stormlord May 22 '18 at 21:17

@Stormlord: my bad, I accidentally checked on 18.04 dependencies. Right you are about the 16.04 kernels having an amd64-microcode dependence. I guess that the LTE kernel packages _should_ depend or at least recommend the latest microcode for the arch. – Martin W May 23 '18 at 20:28

It's a new dependency of linux-image-generic. See

You're right. It looks like both intel and amd64 microcode packages are mandatory from now on. – Stormlord May 25 '18 at 08:06

Thanks! I was wondering the reverse: why my amd processor got an intel microcode update, and this answers that as well. – Organic Marble May 25 '18 at 13:28
