[arncj18-byte]

windows everything updated etc. git, ubuntu, python installed, ran in admin
tried form ubuntu, same result.
every PATH is added as far as i know, virtual machine enabled, wsl enabled. used even AI for assist. can't find what is wrong.
runs the % and returns "failure" from install and update commands.

Here’s a quick, no-nonsense fix that usually clears the “Catastrophic failure” during wsl --install / --update:

TL;DR
Re-enable WSL features, then repair or reinstall the Store-based WSL package without using the Store.

---

1) Turn on the required Windows features (safe to re-run)

dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart

Reboot when prompted.
(These are the official steps for WSL/WSL2 features.)

2) Bypass the Microsoft Store and repair WSL

Option A — Web download (preferred):

wsl --update --web-download
wsl --version

Option B — Reinstall the WSL package:

winget uninstall --id Microsoft.WSL -e
winget install --id Microsoft.WSL -e

Both options install the current Store/WDD WSL build even if the Store is blocked or in a bad state.

3) Install a distro (or just install WSL without one first)

List available distros and install:

wsl --list --online
wsl --install -d Ubuntu

If you only want the WSL platform first, then add a distro later:

wsl --install --no-distribution

(Then wsl --install -d <Name> when ready.)

4) Quick health checks

wsl --version          # shows WSL version + kernel + MSIX package version
wsl --status           # confirms default version and key settings
wsl -l -v              # lists installed distros

If wsl --version prints data, your core install is fine; issues after that are usually distro-specific.

If it still says “Catastrophic failure”

• Windows is too old or half-updated → Fully update Windows and reboot.
• Virtualization really isn’t on (even if you think it is) → Confirm it’s enabled in BIOS/UEFI and that “Virtual Machine Platform” is on (Step 1).
• WSL package is corrupted → Do the winget uninstall/install cycle again (Step 2B), then reboot before wsl --install -d Ubuntu.
• Corporate Store policy → Stick with --web-download or install the MSIXBundle directly from the WSL GitHub Releases page.
