Public bug reported:
Issue:
I've created Ubuntu 20.04.2 bootable USBs (tried two different sticks, and
created on rufus/windows, etcher/macOS, and on Ubuntu 21.04, all following the
Ubuntu bootable creation guide).
I also validated the ISO using the checksum and guide provided.
With a new ThinkPad X1 Nano (i7-1160G7, 512 GB SSD, non-touch screen, default
options otherwise including Windows 10 Pro 20H2, serial number is from January
2021), I hit the "errno 5 input/output" error during installation.
This error occurs after all options have been set, like username, password,
partitioning options, etc., but appears to occur before the disk is actually
written to.
Fortunately, this means that I can boot back into my working Ubuntu 21.04
installation, as I'll go into later.
I've tried this with secure boot enabled and disabled as well.
Moreover, I am always choosing the "Erase disk and install" option since I do
not wish to dual boot.
What does work:
Ubuntu 21.04 installs perfectly fine and works perfectly fine. That's with
secure boot enabled as well, so I doubt that this is related to secure boot. My
hunch is that the 20.04.2 kernel is too old for my X1 Nano, and perhaps there
was a stealth revision to its hardware/firmware since I (anecdotally) see X1
Nano users installing 20.04.2 LTS perfectly fine. My hope is that Ubuntu
20.04.03 LTS naturally works, but I'd prefer to install an LTS version as soon
as possible.
Kernel information:
The installer crashes and goes into an unrecoverable state, so I could not
gather information on the bootable itself. However, I can provide the Ubuntu
21.04 information since it does work.
- Ubuntu 5.11.0-25.27-generic 5.11.22
- lspci-vnvn.log (attached)
Please let me know if you require additional information, and how I can help.
Thank you in advance.
