@linuxluigi I improved the error output for the executed commands on repo initialization. Also I changed the effect of a failing command from an error to a warning since technically the created repo is valid and just doesn't have git and go initialized which could be done manually by the user after he fixes the issues. (If we keep the error, the created folder is deleted automatically by the defered cleanup)
What do you think of that approach?

Btw I decided to pick the minGoVersion 1.15 by running the following:

#! /bin/bash

SCRIPT="curl -fsSL https://github.com/SchwarzIT/go-template/releases/download/v0.2.0/gt-linux-amd64 -o gt-linux
chmod +x gt-linux
./gt-linux new -c /src/test-values.yml"

GOOS=linux GOARCH=amd64 go build -ldflags="-w -s" -o /tmp/gt_linux cmd/gt/*.go
for version in 1.12 1.13 1.14 1.15 1.16 1.17; do
  echo testing version $version
  docker run -it \
    -e GO111MODULE=on \
    -v $(pwd)/pkg/gotemplate/testdata/values.yml:/src/test-values.yml \
    golang:$version \
    /bin/bash -c "$SCRIPT"
done

So basically 1.15 was the first version that didn't fail right away when running gt new.

Awesome, you also fix the problem. That when you run gt without internet connection that it will still works.
Just by accident I run in the problem direkt before I read your PR 🤩
