Can't install on laptop: Invalid "children" token ... Unknown block device type dm #775

Open rscm opened 2 years ago

rscm commented 2 years ago

Describe the bug Wanted to install on a laptop but the installer (GUI) didn't detected the drive. The drive is a SATA SSD disk, but I've also tested with the previous mechanical drive and the issue persisted. Then tried using a YAML file (clr install config) to define the drive on /dev/sda and for a moment worked and it created the partitions but then stopped with an error. (you can read the logs for more details about the error)

I've tried with multiple CLR Linux isos (previous versions) and the same happened

The install media is fine, I use Ventoy and I have a bunch of isos in it I use regularly

Thanks

To Reproduce Steps to reproduce the behavior:

  1. Connect the install media/USB Stick
  2. Boot into CLR
  3. Open the installer
  4. Enter the storage/partition options and see the error there saying it can not detect any drive

Expected behavior I expect that the installer detects the drive on /dev/sda and then let me install the OS

Environment (please complete the following information):

I also hit this bug when trying to install Clear Linux on the machine next to me. If I locally patch lsblk to not emit a "type": "dm" element, I can choose between all available physical block devices in the system and continue with the installation.

I don't think it's a sensible idea to have block_devices.go keep an internal list of expected values that lsblk might produce, especially when it is not exhaustive. Simply skipping over "unknown" elements would be a better solution, instead of having the parser report an error condition. If you disagree, this patch:

diff --git a/storage/block_devices.go b/storage/block_devices.go
index 4746183..44e97bc 100644
--- a/storage/block_devices.go

... could probably fix the problem for this instance of an unexpected value.

Ftr, a workaround to fix the live environment could be this:

sudo mv /usr/sbin/lsblk /usr/sbin/lsblk.real
base64 -d <<EOF > /tmp/lsblk_patched
IyEvYmluL2Jhc2gKL3Vzci9zYmluL2xzYmxrLnJlYWwgIiR7QH0iIHwgc2VkICdzLyJ0eXBlIjog
ImRtIi8idHlwZSI6ICJwYXJ0Ii8nCg==
EOF
sudo cp /tmp/lsblk_patched /usr/sbin/lsblk
chmod 0755 /usr/sbin/lsblk

which will result in /usr/sbin/lsblk become this crude shellscript:

#!/bin/bash
/usr/sbin/lsblk.real "${@}" | sed 's/"type": "dm"/"type": "part"/'

I could complete the installation after performing this unholy procedure. Ymmv.
