%q not implemented

Error message

%q not implemented

What it means

Remote getter error from Get: the requested artifact kind (the `what` argument) is not one of the implemented types (checksum or zip). A programming/usage guard — only "checksum"-style and "zip" fetches are supported by this getter.

Solutions

1. Request a supported artifact type (checksum file or zip) from the getter
2. This indicates an internal caller bug or unsupported plugin-getter configuration; report it if triggered by stock Packer
