Linux version?

[coding-garden-1]

Hi there,
Unlike everyone who says "linux version please" imma just ask -- what do you think is Windows dependent here?
When i ran docker build -t izabela ., it gave me
" => ERROR [internal] load metadata for mcr.microsoft.com/windows/serverco 0.7s

[internal] load metadata for mcr.microsoft.com/windows/servercore:ltsc2019:

---

Dockerfile:1

1 | >>> FROM mcr.microsoft.com/windows/servercore:ltsc2019
2 |
3 | WORKDIR /app

ERROR: failed to solve: mcr.microsoft.com/windows/servercore:ltsc2019: failed to resolve source metadata for mcr.microsoft.com/windows/servercore:ltsc2019: no match for platform in manifest: not found
". So i assume some library used is depending on a windows thing. But none of these languages are Windows-exclusive. It would be great to know what specifically would be Windows dependent so i could make a linux version for all us girlies :)
