Upgrade to Ubuntu 20.04 LTS

Now that Ubuntu 20.04 LTS (Long Term Support) is out, here’s a quick guide to upgrade to Ubuntu 20.04 LTS. You can ONLY upgrade from either Ubuntu 18.04 LTS or 19.10. If you have older versions of Ubuntu, it may not work. I suggest you back up your VM before running the upgrade, so you can quicky recover if something goes awry. This upgrade process will require sudo access.

# login as root
sudo -i
# check your current version
lsb_release -a
# update packages
apt update -y
apt upgrade -y
# reboot server
reboot
# remove old kernels
apt --purge autoremove
# install update manager core
apt install update-manager-core
# finally, perform the upgrade
do-release-upgrade -d
# reboot the server
reboot
# after reboot confirm
lsb_release -a

Windows 10 Activation

I recently upgraded my system which involved a new motherboard. I brought over the old hard drive from my previous machine to the new one. I booted it. Bang! And just like that Microsoft deactivated my account. I called them. They said they have no record of it based on the email addresses that I’ve provided.

I told them that I’ve upgraded from Windows 7 to Windows 10 a few years back. Microsoft proceeded to tell me that I needed to provide them my Windows 7 product key. Now, I have to look for it. I have no idea where it is. If I can’t find it. I won’t be able to activate it. I’m sure I’m not the only who got screwed for upgrading their hardware.

Windows 10 Activation

Essentially, I’m back to using Linux again, which by the way don’t have draconian methods for simple things like hardware changes.
