Install Go on Ubuntu 18.04, Using Snap

Refer: https://www.codeooze.com/ubuntu/ubuntu-18-golang-snap/

Step 1: Check if Go is already installed
$ go version

Step 2: Install Go using snap, see what's available
$ snap info go

Step 3: Classic confinement error
Explanation: Most snaps are installed in confined containers and only have limited access to other system resources. However, snaps published with classic confinement have greater access to the rest of the system, which is desirable for scripting packages such as Go.

$ sudo snap install go --classic

Step 4: Verify the install
$ snap list
$ go version
$ go env

Conclusion
You have now successfully installed Go in Ubuntu 18 using snap

Windows Always Shows “Missing Important Fixes”

Fixing "Your device is missing important security and quality fixes."
Refer: https://www.youtube.com/watch?v=1wjtBFTPR00

On a Windows 10 based computer, the following warning message is displayed in Update and Security center: "We couldn't connect to the update service. Your device is at risk because it's out of date and missing important security and quality updates. Let’s get you back on track so Windows can run more securely."

Telemetry Level: There is an option in Windows Group Policy Editor that allows you to control the levels of the Telemetry. It just so happens that some Windows Updates (especially the cumulative updates) won’t be delivered to your system if your Telemetry level is set to Security only.

This tutorial will apply for computers, laptops, desktops,and tablets running the Windows 10 operating system (Professional, Enterprise, Education) from all supported hardware manufactures, like Dell, HP, Acer, Asus, Toshiba,Lenovo, and Samsung).

Here's the fix

gpedit.msc
"Computer Configuration"
"Administrative Templates"
"Windows Components"
"Data Collection and Preview Builds"
"Allow Telemetry"

Originally "Not Configured"
Changing to:
Enabled, Enhanced

Disable Windows Git Credential Manager

Refer: https://stackoverflow.com/questions/37182847/how-do-i-disable-git-credential-manager-for-windows

OK, I discovered that you need to either avoid checking the "Git Credential Manager" checkbox during the Git for Windows installer, or (after installation) run the Bash shell as Administrator and use git config --edit --system to remove the helper = manager line so that it is no longer registered as a credential helper.

For bonus points, use git config --edit --global and insert:

git config --edit --system

To disable the OpenSSH credentials popup too.

VirtualBox Company VPN Issues with DNS

Refer: https://superuser.com/questions/570984/virtualbox-guest-ubuntu-loses-dns-when-host-connects-to-vpn

$ sudo gedit /etc/NetworkManager/NetworkManager.conf

Comment out, the plugins line below (shown before commenting)

[main]
plugins=ifupdown,keyfile,ofono
# dns=dnsmasq

Notes: had a very similar situation with Lubuntu 16.04 (should be identical in other Ubuntus) but this fix did not improve the situation. At least with 16.04, the problem appears to be that NetworkManager uses a local DNS proxy (dnsmasq), and this doesn't play nice with VPN connections, at least in the default configuration.

Commenting/deleting dns=dnsmasq in /etc/NetworkManager/NetworkManager.conf

Note: This fixed was applied too on the Windows host, but it did not seem to make a difference, go ahead and do both.
