Installing TF 0.12.31 - No keybase install found

I need to upgrade our codebase from the current 0.12.29 to 1.x

As part of that process I need to upgrade to the latest version of 0.12

I used tfenv to install the latest version of 0.12 using tfenv install latest:^0.12 which installs 0.12.31 but it comes up with a warning.

Downloading SHA hash file from No keybase install found, skipping OpenPGP signature verification

I’m not sure what, if anything, I need to do about the “No keybase installed” message and I don’t know if it’s a tfenv issue or a Terraform issue.

Can anyone advise please?
