python – ChromiumOS cros_sdk Unhandled Exception

I’m trying to build Chromium OS.

But an error is bullying me.

My System:

Linux Ubuntu x86_64
i5-9600k
16gb Memory
2TB HardDisk -< used for chromium build

Command i runned:

mkdir chromium && cd chromium && vi .gclient

.gclient file

solutions = [
  {
    "name": "src",
    "url": "https://chromium.googlesource.com/chromium/src.git@96.0.4664.215",
    "managed": False,
    "custom_deps": {},
    "custom_vars": {},
  },
]
target_os = ["chromeos"]

mkdir whaleos && cd whaleos
repo init -u https://github.com/naverwhale/whaleos-manifest.git -b main
repo sync

this code is i have runned

Anyway, i have an error with using cros_sdk

cros_sdk --chrome_root ../chromium

i runned this and this makes an Error like this:
