[Bug 1897860] Re: flash-kernel does not generate initramfs on SolidRun MACCHIATObin

Wed Sep 30 08:35:19 UTC 2020

I have repeated the installation procedure and captured logging. flash-
kernel exits with exit code 3:

and that gives the following logging in curtin:

Title:
  flash-kernel does not generate initramfs on SolidRun MACCHIATObin

Status in flash-kernel package in Ubuntu:
  Confirmed

Bug description:
  Ubuntu Focal installer hits the following in the installation process
  when flash-kernel gets triggerd:

  Using DTB: marvell/armada-8040-mcbin.dtb
  Couldn't find DTB armada-8040-mcbin.dtb on the following paths:
  /etc/flash-kernel/dtbs /usr/lib/linux-image- /lib/firmware//device-tree/
  Installing  into /boot/dtbs//marvell/armada-8040-mcbin.dtb
  cp: cannot stat '': No such file or directory

  the DTB _is_ actually installed in
  "/boot/dtbs//marvell/armada-8040-mcbin.dtb". However, the initramfs is
  never created, maybe because of exit 1 code in the aforementioned
  output. Invoking "/usr/sbin/update-initramfs.curtin-disabled -u -k
  all" by hand does create a initramfs for all available kernels, and
  the system is able to boot fine afterwards.

  I *think* this also prevents the Focal installer (curtin) to complete
  succesfully, but it reboots almost immediately after hitting an error,
  so I don't know for sure.
