Unattended Upgrades With Mailgun

System updates are very important as they contain bug fixes, security patches and feature improvements. Sometimes these updates can break system functions so it’s always a good idea to send yourself a changelog of what has been updated to help problem solve in the event of an update breaking something.

We’re going to use a mail service called Mailgun for no other reason than it’s my preferred choice of email delivery provider, they’re also currently free.

First we’re going to configure unattended upgrades to upgrade our system, I’m using Ubuntu 18.04 though you should be able to use this guide on different versions of Ubuntu.

I run into this issue literally all the time, if you try to install ubuntu on an Nvidia graphics card you may need to use the “nomodeset” string in your grub menu before booting until you can install graphics drivers for your graphics card. Press “e” with either “try ubuntu” or “install ubuntu”, a new screen will appear then simply fine the string “quiet splash” and type “nomodeset” beforehand, you should now be able to get into the operating system with a basic graphics driver, this option is temporary so you’ll likely need to use it again once Ubuntu is…

Kernel_security_check_failure Windows 10 Fix

I recently started using a machine with an AMD A10-7870K, an older AMD APU from their FM2+ socket. After installing the latest version of Windows 10 version 1903 everything seemed to run great, noticeably faster than my older i3-2120 machine.

Anyway after a short-while of usage a kept receiving a BSOD with the error message “Kernel_security_check_failure” and then my machine would just reboot, after fiddling around with many drivers and browsing numerous support forums I came to the conclusion that the issue was with the Meltdown and Spectre patches being applied to my system via Windows update, I tried uninstalling the supposed Windows updates which proved to have no effect I still kept having random BSOD with the same error message.
