I get 18.10 Beta image by using BitTorrent network. I hope you will follow this as it will help reduce community server's loads. However, I use GNOME Disk Utility to make a bootable USB to install it.

1. User Interface


The most notable change here is the new icon theme called Yaru. It's actually a complete suite of themes: icon, GTK2 & GTK3, and GNOME Shell themes. It's the rumored Ubuntu Community Theme which you can contribute to at https://github.com/ubuntu/yaru. With this theme, 18.10 is ready for HiDPI screens i.e. Apple Retina Display. This Yaru theme suite is now the default on Ubuntu 18.10.

2. GNOME 3.30


Cosmic is the first version of Ubuntu which features GNOME 3.30 "Almeria". See below where Gedit, Calendar, Document Viewer, and Disk Usage Utility all reached version 3.30.



3. File Manager


While the rest is already 3.30, the file manager is still 3.26. You know, GNOME 3.30 does not have icons on desktop area feature, so keeping 3.26 which still has it keeps the feature. This way, it's still possible for us to put favorite apps on desktop like second picture below.

Icons on desktop area is still possible


4. Repository


It is now cosmic. You may see https://launchpad.net/ubuntu/+archivemirrors to find out whether a local mirror is already available in your country.



5. Let's Contribute (You can report bug too!)


An issue I see immediately after installing, is, taking screenshot freezes the desktop and immediately logged it out. I managed to send my bug report here. Bug hunting and reporting are not scary, it won't eat babies, instead it's automatically done by the help of ubuntu-bug command line. (note: anyway, finally I use scrot to take all screenshots here)

Everybody can report bug for 18.10 as long as he/she have strong determination to help the community and has good internet access.

To give you general picture:
  • 1) download the ISO image of the Beta
  • 2) install it safely on your computer
  • 3) run programs and explore the features available as much as possible
  • 4) you will eventually find an error or bug related to a program (a package)
  • 5) run command line  $ ubuntu-bug package-name  and let Ubuntu process the rest of reporting
Of course you will need a Launchpad account to do this. If you don't own one, register first. You can learn more details about bug reporting here. Happy contributing!

For example: my bug report generated and sent automatically to Ubuntu bug center

That's All!


I hope this short review helps you to recognize what's new on the anticipated 18.10 and also to start contributing by doing bug report. Personally, I find 18.10 will be very interesting since GNOME 3.30 is the official desktop as I reviewed few days ago. That's all, we're waiting for October, enjoy Beta!
