Hello, I tested v3 of this change, which looks great. Unfortunately, when running ./pre-inst-env guix import go --recursive rclone I get the following backtrace: --8<---------------cut here---------------start------------->8--- following redirection to `https://github.com/qingstor/qingstor-sdk-go?go-get=1'...
