I am new to proxmox and having trouble connecting to the internet. It has to be the way the DNS is set up but messing with that last time is why I had to install it from scratch again. Once I lost the web interface, I couldn't get it back, no matter what I changed on the CLI.

I think in this case it's DNS: I can ping 8.8.8.8, but I can't ping google.com. I also get the following error when I attempt to download an ISO using a link:

invalid server response: '500 Can't connect to releases.ubuntu.com:443 (Temporary failure in name resolution)' (500)

I have my cat /etc/network/interfaces

I have my cat /etc/resolv.conf

If I were to open up my MAC OS and look at Network > TCP/IP my Router comes up as 192.168.1.1

This is week 2, install/setup attempt TWO the last time around, I had to reset everything, and I gave proxmox the benefit of the doubt because I screwed up by not having the server plugged into the internet, but this time I did have everything plugged in. I did an automated setup, I have NO switches, NO extra routers, NOTHING. I plugged the nic from the router from my ISP into the computer that I have proxmox on, then did a fresh install. I can access it from the web interface, but when I try to get the ubuntu ISO, it errors out, and when I try to ping a website, I get an error:

ping google.com
ping: google.com: Temporary failure in name resolution

My goals are simple:
1) install promox
2) learn to use promox
3) branch out into other IT as I need and grow my abilities.

To proxmox:

I know you guys are great at what you do, and I am sure you are way beyond my understanding. I, however, can't be the only noob that gets stuck like this, like plugging in the computer (hardline to a simple isp router) and installing so I can sit down and learn proxmox. But since it doesn't connect like a MAC or Windows I now have to learn networking just to get to the part of learning Proxmox.

All I ask is please take a look at your conversion rate of how many people download vs actually end up using the system. If the conversion rate is low, it just might be newbies are already intimidated to use and learn the system and not being able to plug in a computer they just bought and ran with it may deter them from learning more. The only reason I'm sticking in there and not stopping or converting to VMware is that I'm a software engineer, and I'm hoping the effort I'm putting into learning your system will be worth my time. So please for your next update maybe take a second and think of the noobs I mean anyone who needed advanced settings would be advanced enough to know how to use those settings.

And this is bad why?

You want to setup infrastructure where you will be able to run multiple virtual machines. To do that successfully you have to know about networking.

BTW: 127.0.0.1 is likely not the DNS resolver for your Proxmox host. Put 192.168.1.1 into the DNS resolver settings (or edit /etc/resolv.conf) if your router runs a DNS resolver for your network.
