For 0x206c2:
Refer to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=907402

0x206c2 is missing *from the Debian and Ubuntu packages* on purpose, but we could ship it if Intel explicitly tells us it is not going to permanently disable a box that has a very old BIOS with the blacklisted SINIT ACM for Intel TXT AND which happens to have Intel-TXT-based secure boot enabled in BIOS.

For 0x106e5, 0x306e4:
They are present in the intel-microcode packages in Debian, so I will leave the answer to the Ubuntu maintainer. Are you sure they are really missing from /lib/firmware/intel-ucode?

This will check if the microcodes are in the package (run it with the package installed and no extra manually-added microcodes in /lib/firmware/intel-ucode or /usr/share/misc/intel-microcode*)

iucode_tool -q -l -s 0x106e5 -s 0x306e4 /lib/firmware/intel-ucode

" reports they exist, then your issue is that they're not being installed to the initramfs.
