I just want to say thank you all for your responses. You guys are amazing.

I'm trying to set up vagrant on my windows machine, but I can never installed it properly, there's always some error when installing a box (for example, the trusty64 hashicorp). It always says "it can't find this box", no matter which box I use

That's cool. Are you running ubuntu with unity or any other DE environment?

For a while I was running Lubuntu with AwesomeWM which I really liked but I had a hardware failure so now I'm just running stock Ubuntu with Unity because I haven't taken the time to setup AwesomeWM again. I can't say I'm sad that Unity is being discontinued because it's never been completely stable for me.
