[Bug 1835660] Re: initramfs unpacking failed

[Daniel Silva Capera]

I am having the same trouble, but during INSTALLATION, I already
installed Ubuntu 20.04 twice and I haven't access to it yet. The first
time I got black screen (with safe graphics installation) then normal
installation didn't let me to install, and I try to reinstall with safe
graphics again. I got the same problem. (The first time I tried Ibunto
on normal mode without conplications, then after installing I had the
trouble).

Title:
  initramfs unpacking failed

Status in initramfs-tools package in Ubuntu:
  Confirmed
Status in linux package in Ubuntu:
  Confirmed

Bug description:
  "initramfs unpacking failed: Decoding failed",  message appears on
  boot up.

  If I "update-initramfs" using gzip instead of lz, then boot up passes
  without decoding failed message.

  ---

  However, we currently believe that the decoding error reported in
  dmesg is actually harmless and has no impact on usability on the
  system.

  Switching from lz4 to gzip compression, simply papers over the
  warning, without any benefits, and slows down boot.

  Kernel should be fixed to correctly parse lz4 compressed initrds, or
  at least lower the warning, to not be user visible as an error.
