Preparing for Leap 15.0
OpenSUSE Leap 15.0 is expected to be released on Friday May 25th. That’s just a few days away. I have already posted two guides to different aspects of installing:
So here’s one more post before the release. I will fill in some of the gaps left by the other guides.
Some quick notes
First some notes. If you have already been testing pre-release versions of openSUSE 15.0, then now would be a good time to run
from a root command line. This should bring your system to the final release version. After that, you should update the usual way with “zypper up” or with the desktop update applet, or with Yast online update.
If you have not been testing pre-release version, but want to get an early start, then you here’s how you can install now. Download the NET installer iso from the download page, and burn to a CD or to a USB flash drive. And then use that media for an install. Although the downloaded installer is from an earlier pre-release version, the NET installer will install from the online repos. And those online repos already contain the software for the final Leap 15.0 release.
Choosing a Desktop Environment
When installing Leap 15.0, one of the screens you will see will allow you to select the Desktop Environment that you want to install.
You can see the choices in the screenshot above. The obvious choices are for KDE Plasma and for Gnome. The third choice is for a server. Select this if you don’t want to install a desktop, or want a minimal desktop for administration use.
The next choice is for “Transactional Server”. The important difference here, is that with the transactional server you can have atomic updates. The root file system should use “btrfs”. When you do transactional updates, you will be applying updates to a “btrfs” snapshot and not to the running system. So the updating won’t interfere with what you are running. When done updating, you should reboot. And that should take you to the snapshot that was just updated. Or, to say it differently, before rebooting you continue to run the non-updated system. After the reboot, you are switched to the updated system.
I will note here that I have not personally tried the transactional server.
The final choice is for “Custom”. Use that if you want something other than the listed choices. For example, select “Custom” if you want the XFCE desktop or the MATE desktop.
If you plan to use “Custom”, then you should first click on “Configure Online Repositories”. That’s because you probably want to install software that is not on the installer DVD. So you will need to install that from the online repos.
Once you select “Custom” and click “Next” you will be taken to the software selection page, where you can decide what you want to install.
I’ll not that if you are new to openSUSE, it is probably wiser to go with KDE or Gnome for your first install.
The summary page
When you have finished most of the configuration for your install (partitioning, defining the initial user, timezone, desktop), you will see a summary page.
On the summary page, I usually click “enable” in the line about SSH service. That’s because I want to enable the service. And then I usually click “open” on the next line, to allow inbound SSH connections through the firewall (outbound connections are automatically allowed).
Apart from that, you can click any of the heading lines to make changes in that section. I sometimes click the “Booting” section to change the timeout on the boot menu. And I usually click “Software” to select additional software that I want to install. On the software selection screen, I then click “Details” to show more details of what software I can select.
When done with the summary screen, click “Install” at the bottom right. Until you click that, no changes have been made to your disk. You can still abort up until then, without installing anything and without changing what was already on your disk.
After clicking “Install”, you are given a second prompt to say that you are sure. And after that, the actual install begins.
Happy installing. I hope you can enjoy Leap 15.0. It looks as if it will be a pretty solid system.
