My OS is windows 10 and I install ubuntu16.04 on virtualbox. So inside the virtualbox, I start to build a local ushahidi website on ubuntu 16.04. Here is a problem. When I ran "vagrant up", It can't pass this description "default: SSH auth method: private key". Then, it shows an error message that "Time out while waiting for the machine to boot. This means that Vagrant was unable to communicate with the guest machine within the configured ("config.vm.boot_timeout" value) time period.
I guess this may be nothing about Ushahidi but some problems on using double layer of virtaulbox?
I hope someone can give me a solution. Thank you!
