Sorry, wrong repository - please ignore the previous post (I was still
using the broken package version)
Second attempt:
$ sudo add-apt-repository ppa:ubuntu-security-proposed/ppa
$ sudo apt-get update
$ sudo apt install intel-microcode
$ sudo reboot
$ sudo reboot
$ apt policy intel-microcode
OK, just tried the upgrade:
$ apt list --upgradable
Listing... Done
intel-microcode/bionic-updates,bionic-security 3.20191115.1ubuntu0.18.04.1
amd64 [upgradable from: 3.20180312.0~ubuntu18.04.1]
linux-headers-generic/bionic-updates 4.15.0.72.74 amd64 [upgradable from:
4.15.0.70.72]
Thanks for looking into this!
$ iucode-tool -S

So, yes, you did the conversion correctly.
BTW we are using legacy MBR boot mode in case this matters?
