Hi @endorama Thank you for bringing this issue to our attention. We are looking into this issue and will update you on this issue after investigating.

@RaviAkshintala I confirm the presence of this issue, it is affecting all our pipelines that rely on pre-installed Terraform.
It could be worked around by setting up specific version of Terraform (either 1.9.8 or 1.10.1) manually in a dedicated step - but then, that defeats the purpose of having Terraform pre-installed on the runner.
(Yes, it's generally better to do that anyway, but using the pre-installed binary is a tiny bit faster and more convenient.)

I've read that you (GitHub) release a new version of the runner images (with updated packages) more of less once a week. I also see that the last (current) version with Terraform 1.10.0 was released about a week ago.
Is there any chance a new runner image release, with Terraform 1.10.1, will be rolled out in the next 24 hours?

If not, please let us know, so that we can arrange ourselves appropriately (ie. update all the pipelines so they use specific Terraform version and do not rely on the pre-installed binary).

Hi @patrik-simunic-cz The latest version of Terraform, 1.10.1, will be included in this week's image rollout. Thanks.

Hi @endorama The latest version of Terraform is included in the Ubuntu 20 and 22 images. Kindly sync the main. We are closing this issue. Thanks.
