[Vagrant] ダウンロードしたboxの展開に失敗する場合の対処法

Vagrantをインストールし直したら以下のエラーが出るようになった。複数のBoxを試したけど必ずエラー。どうやら自分の環境の問題っぽい。

$ vagrant box add hashicorp/precise32

ネットを検索したら、Vagrant同梱の解凍ソフトを入れ替えて解決した例が見つかった。なぞってやってみたら自分も解決した。

Error while adding Vagrant box in windows xp · Issue #3869 · mitchellh/vagrant · GitHub

my solution was to download the basic_bsdtar.exe from here http://sourceforge.net/projects/mingw/files/MinGW/Extension/bsdtar/ and rename it to bsdtar.exe and place it in C:\HashiCorp\Vagrant\embedded\gnuwin32\bin\

結果オーライだけど原因はわからず。
