4.1 Installing Ubuntu
A Ubuntu installation is straightforward and can replace Windows altogether or can be installed beside Windows (for a dual boot option). Visit the Ubuntu Installation Tutorial for the simple instructions provided by Canonical. You can easily become familiar with the installation process by trying it out once or twice—it doesn’t hurt to practise!
The best choice is to install the latest Ubuntu LTS (Long Term Supported) on your own computer as the base operating system. This chapter also provides various options including virtual machines and cloud servers.
sudo apt update; sudo apt upgrade sudo apt install wajig wajig update; wajig upgrade wajig install python3-pip pip3 install wajig
Be sure to log out and log back in after the pip3
install so that the system will refresh the PATH to include
~/.local/bin (where pip3 installs
commands). You could do the following, but it is not usually required:
echo 'PATH=~/.local/bin:$PATH' >> ~/.bashrc
If you have set up Ubuntu on a server in the cloud then a remote desktop connection can be established using X2Go. This is a good alternative to a command line connection in a terminal using ssh. X2Go usually requires the MATE desktop and the X2Go server to be installed on the cloud server. This can take 15 minutes or so:
wajig install ubuntu-mate-desktop x2goserver
For any questions asked during the install select the default option (e.g., gdm3).
In general, you may also like to install the following packages:
wajig install emacs
Some other useful initial setup includes:
sudo timedatectl set-timezone Australia/Canberra
To keep the system automatically updated add a regular task to the system crontab.
sudo crontab -e
Add the following line to update at 3am every day. Change
your own username and create the sub-directory in your home directory.
0 3 * * * (wajig update; wajig distupgrade --yes) > /home/kayon/cronlog/cronlog_`date +\%Y\%m\%d`.log 2>&1
