Public bug reported:
Sysadmin reported in #ubuntu (later #ubuntu-kernel) the 16.04 ubuntu-
server failed due to being unable to configure linux-
image-4.4.0-21-generic.
Lots of diagnostics and one SSH remote session later we seem to have
narrowed it down to the installer.
The cause of the error message appears to be that the symlink names in
/dev/disk/by-uuid/ haven't been updated after the partitioning stage if
there were pre-existing partitions and file-systems on the install
device, *and* the sysadmin chose to format the existing partitions when
selecting mountpoints.
In this case a hardware RAID device presents:
/dev/sda1 (/boot/)
/dev/sda2 (swap)
/dev/sda3 (/)
>From the shell I noticed:
