<issue_to_address>
**issue:** The report is dated 2025-09-06 but all updated rootfs references point to the future version `archriscv-2026-08-27`; when users follow the report at its stated update date, the `wget` URL requests an unavailable archive and the documented tested version cannot be reproduced.

**Triggers:** When following this report before 2026-08-27.

**Suggested fix:** Use the actual tested 2025 rootfs/build dates consistently, or update `last_update` and the report only when the 2026 archive actually exists.
</issue_to_address>

### Comment 2
<location path="Duo_S/ArchLinux/README.md" line_range="130" />
<code_context>

 ```shell
-dd if=milkv-duos-sd_2025-0831-0547.img of=/dev/sdc bs=1M status=progress
+dd if=milkv-duos-sd_2026-0906-2125.img of=/dev/sdc bs=1M status=progress
 ```

</code_context>
<issue_to_address>
**issue:** The English flashing command looks for `milkv-duos-sd_2026-0906-2125.img` in the current directory, while the build and loop-setup instructions produce and reference it under `out/`; following the documented steps therefore makes `dd` fail with a missing input file unless the user manually changes directories or adds the prefix.

**Triggers:** When the command is run from the repository root or from the `/mnt/duo-rootfs` directory left by the preceding steps.

**Suggested fix:** Use `dd if=out/milkv-duos-sd_2026-0906-2125.img ...`, matching the Chinese instructions and the build output path.

```suggestion
dd if=out/milkv-duos-sd_2026-0906-2125.img of=/dev/sdc bs=1M status=progress
```
