ラズパイでアプリをホストしようとgit cloneしようとしたときに表題のエラーが発生。

/opt $ git clone git@github.com:USER/YOUR_REPOSITORY.git
fatal: could not create work tree dir YOUR_REPOSITORY: Permission denied

私個人で使うマシンなので特定ユーザーに/opt以下の所有権を与えるとgit cloneが成功する

$ sudo chown -R $USER:$USER /opt

$ git clone git@github.com:USER/YOUR_REPOSITORY.git
Cloning into 'YOUR_REPOSITORY'...
