Newest golang buildpack version cannot install go

[balamut-google]

There is something wrong with the recent version of go binary dependencies that ./scripts/install_go.sh tries to install.
When curl fetches https://buildpacks.cloudfoundry.org/dependencies/go/go_1.25.6_linux_x64_cflinuxfs3_0ed64e3b.tgz to /tmp directory, the resulting output is XML message with access denied error, instead of go installation archive, like this:

<?xml version="1.0" encoding="UTF-8"?>
<Error><Code>AccessDenied</Code><Message>Access Denied</Message><RequestId>2EKSYXV0XD4A5G6F</RequestId><HostId>cvpIwKA...CwZGOwTxtOaw4=</HostId></Error>

This behavior is likely to break installation for users that rely on the newest version of buildpacks.

cflinuxfs3 has been deprecated three years ago. I would suggest looking into updating kf to cflinuxfs4 and already start looking into cflinuxfs5 as well.

[balamut-google]

Understood, but

go-buildpack/scripts/install_go.sh

Line 8 in f05f503

if [[ "${CF_STACK:-}" != "cflinuxfs3" && "${CF_STACK:-}" != "cflinuxfs4" ]]; then

still allows cslinuxfs3 but disallows cflinuxfs5.

Yes, you're right, I've created a fix in cloudfoundry/buildpacks-github-config#259

[balamut-google]

Thank you!

@balamut-google cloudfoundry/buildpacks-github-config#273 dropped cflnuxfs3 support, so I closed my PR. I suggest contacting the author of the PR dropping cflinuxfs3 if questions remain.

@balamut-google check https://github.com/cloudfoundry/go-buildpack/blob/master/scripts/install_go.sh#L8 the latest versions does not use cflinuxfs3 anymore

@balamut-google Please, close the issue if it is not relevant anymore
