Cf push fails in the buildpack compile phase with a sha256 mismatch

[JoschuaGoetz]

What version of Cloud Foundry and CF CLI are you using? (i.e. What is the output of running cf curl /v2/info && cf version? Cloud foundry version: v40.12.0 cf version: 8.7.11+b1b4068.2024-07-09

What version of the buildpack you are using? v1.8.27

Pushing an app with cf push -f manifest.yml <app-name> fails in the compile phase right after downloading go 1.19 with a sha256 mismatch. Updating the cli and trying different buidpack versions does not work. Logs :

This issue is only occurring when using a git url as buildpack. Using just python_buildpack works.

You are likely using an offline buildpack in that case, right? That only works if you actually have that offline buildpack in your Cloud Foundry instance. And it also needs to match the version you actually need...

[JoschuaGoetz]

Yeah i agree this "workaround" is very conditional. But might just work if you need a version deployed. I assume i was just lucky to have the versions i need cached on the cf instance

Seems like this issue magically disappeared. So closing this.
