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

Tasksel Lampserver

Tasksel is a Debian/Ubuntu tool that installs multiple related packages as a co-ordinated “task” onto your system. It’s similar to meta-packages where tasks are dericed from from Ubuntu package managers like Synaptic or KPackageKit.

Here’s a quickway to install a lamp server.

# install tasksel first if you don't have it.
apt install tasksel
# install a lamp server package
tasksel install lamp-server

Google SDK Install on Debian or Ubuntu

Here’s the script.
