Buildpack not working

[weoutfun]

The buildpack now returns error for every stack. For example: Requested GDAL Version (3.5.0) is not available for this stack (heroku-18)

I am suspecting that it is a problem with the S3 storage. It is probably no longer active/accessible

The buildpack works for me:

$ mkdir testcase && cd $_
$ git init && touch test && git add -A && git commit -m 'Initial commit'
...
$ h create --buildpack https://github.com/heroku/heroku-geo-buildpack

From the error message I see you are using Heroku-18. The Heroku-18 stack is EOL and can no longer be used on Heroku: https://devcenter.heroku.com/changelog-items/2583

I presume you are using the Geo buildpack via another means (eg Dokku)? (In the future, including the full build log and any other relevant details like the platform on which it is being run would be helpful.)

If so, you'll need to update to a newer stack (Heroku-20 or Heroku-22).

Lastly, you'll also need the latest version of this buildpack, so that you have: https://github.com/heroku/heroku-geo-buildpack/commit/c452e7234c3bca7ce1d3a91096e53d8f5a35806d

Thanks for the timely response!

Indeed I am using Dokku and I have been using the buildpack for a couple of years now(initially with Heroku, then a year now with Dokku) and never had an issue except today. I initially had GDAL_VERSION 2.4.2 and thought that was the issue but switching to 3.5.0 raises the same error. Here's the build log:

       !     Aborting.

I see that there hasn't been an update to the library recently so I am wondering why the build is suddenly not working. My last successful build was about a week ago

[edmorley]

The binaries for EOL stacks were removed recently (since they are unused on Heroku, since it's not possible to build on these stacks there), so you will need to update to a newer stack:

From the error message I see you are using Heroku-18. The Heroku-18 stack is EOL and can no longer be used on Heroku: https://devcenter.heroku.com/changelog-items/2583

[weoutfun]

I see now. Thanks! I have resolved it!

[edmorley]

In #46 I've removed the leftover Heroku-18 references in the README to make the lack of Heroku-18 support clearer.

[weoutfun]

@edmorley That surely makes things clearer from the docs. Thanks!
