I spent almost 3 hours figuring out this issue I have just encountered.
In my personal laptop, I plan to install centos/7 box but I got some weird issue. Something like permission thing, after an hour of fixing still I can't solve my problem.
So, I switch to bento/centos-6-7 and it works. It downloads the box and installed it. However when I try to clone the git repo. I got another issue. something in the git.
so, I downloaded again another box but this time, it is bento/centos7-2. hopefully, it will work now.
