Fetch generic linux sources fails with WSL

[rgaiacs]

I'm helping @yuvipanda with cryptnono/cryptnono#53 but my development environment is based on Windows Subsystem for Linux (WSL) + Docker Hub. When I run

kubectl-trace/build/init/fetch-linux-headers.sh

Line 52 in 42eaafc

curl -sSL "https://www.kernel.org/pub/linux/kernel/v${major_version}.x/linux-$kernel_version.tar.gz" \

the URL used was

https://www.kernel.org/pub/linux/kernel/v6.x/linux-6.6.87.2.tar.gz

The above URL results in 404. My impression is that the above URL should be

https://www.kernel.org/pub/linux/kernel/v6.x/linux-6.6.87.tar.gz

This is caused by

kubectl-trace/build/init/fetch-linux-headers.sh

Lines 39 to 42 in 42eaafc

	# 4.19.76-linuxkit -> 4.19.76
	# 4.14.154-128.181.amzn2.x86_64 -> 4.14.154
	# 4.19.76+gcp-something -> 4.19.76
	kernel_version="$(echo "${KERNEL_VERSION}" | awk -vFS='[-+]' '{ print $1 }')"
