Bug Description

Eoan daily image from Oct-11

The subiquity server installation repeatedly fails in BIOS mode on a system, claiming there is no installation target found. However switching VTs there is /dev/sdb available. The special thing about that box is that enumeration starts with sdb, skipping sda (I believe this is taken by a usb CF card reader even though there is no card inserted).

ValueError: probe_data missing bcache data

Why isnt' the bcache kernel module present on this image.

This looks similar to the ARM64 failure: LP: #1845561

FWIW, this is definitely not caused by the first usable disk being labelled sdb :)

@mwhudson, yes I thought that much after Ryan's comment. Just that why a certain module is not in the image I cannot say either. Not doing those. :)
