I mis-read the code in the previous comment; the condition is fine. To figure it out I added some lines that do each test independently so as to identify which of the three fails. That reveals the problem is the block-device test:

That should be done by a call to hook-functions::setup_dev_linux() before dep_add_modules_mount() There's a waypoint for it in debian/bootstrap-base.postinst before the install_kernel stage. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/1582899 Title: in-target: mkinitramfs: failed to determine device for / Status in base-installer package in Ubuntu: New Status in initramfs-tools package in Ubuntu: New Bug description: 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: root@tmpstorage:/# ll /dev/disk/by-uuid/ total 0 lrwxrwxrwx 1 root root 10 May 17 19:39 130e4419-4bfd-46d2-87f9-62e5379bf591 -> ../../sda1 lrwxrwxrwx 1 root root 10 May 17 19:39 127d3fa1-c07c-48e4-9e26-1b926d37625c -> ../../sda3 lrwxrwxrwx 1 root root 10 May 17 19:39 78b88456-2b0b-4265-9ed2-5db61522d887 -> ../../sda2 lrwxrwxrwx 1 root root 9 May 17 19:39 2016-04-20-22-45-29-00 -> ../../sr1 drwxr-xr-x 6 root root 120 May 17 19:39 .. drwxr-xr-x 2 root root 120 May 17 19:39 . root@tmpstorage:/# blkid /dev/sda* /dev/sda: PTUUID="a84e60fd" PTTYPE="dos" /dev/sda1: UUID="61365714-8ff7-47a2-8035-8aed9e3191a6" TYPE="ext4" PARTUUID="a84e60fd-01" /dev/sda2: UUID="78b88456-2b0b-4265-9ed2-5db61522d887" TYPE="swap" PARTUUID="a84e60fd-02" /dev/sda3: UUID="75f68451-9472-47c7-9efc-ed032bfa9987" TYPE="ext4" PARTUUID="a84e60fd-03" More details to follow.
