In this tutorial, we will show you how to upgrade from lower openSUSE like 15.0 or 15.0 to 15.3.
In my case, I’m using openSUSE LEAP 15.1, before starting the upgrade, we strongly advise backing your actual Data in case you are using this release in production environments.
Step 1 : Refresh The repositories
So First thing I have to do is to refresh my actual repositories with this command
sudo zypper ref
Step 2: Updates the Actual packages
you can updates with command zypper up
unixcop-opensuse:~ # sudo zypper upStep 3 : Reboot your machine and check your system info
sudo reboot
sudo hostnamectl 
Enabling Update repository:
Run the following command to check if the update repository already exists and is enabled.
zypper repos --uri | grep -i update
If the ‘Enabled’ column says ‘No’, enable it by issuing the below command:
$ zypper modifyrepo –enable repo-update
Updating the repositories:
Check if your Leap repos defined in ‘/etc/zypp/repos.d/’ are using the ‘$releasever’ variable already using the following command.
$ cat /etc/zypp/repos.d/*.repo
In most cases, it should already have the ‘$releasever’ variable. They are still hard-coded with a particular Leap version number, then run the following command to modify them.
$ sudo sed -i 's/15.1/${releasever}/g' /etc/zypp/repos.d/*.repo
To refresh the openSUSE Leap 15.3 repositories, run:
$ sudo zypper --releasever=15.3 refresh
It’s time to upgrade
zypper --releasever=15.3 dup --force-resolution The –force-resolution is important to avoid answering on this question
So This action will take some time to Download and upgrade all packages
When this action successfully completed that you have to reboot your server.
rebootCheck your system Now
hostnamectl
zypper ls -r
Done
Hi Mel,
I used your info to upgrade to 153 (from 15.2). It all went well but after the upgrade it syas Leap 15.3 (hotnamectl) but it still shows 15.2
repositories (with zypper ls -r). Should i be worried or is there a way to fix this?
Thanks in advance,
Michel
Michel ,
please dont forget the sed …. command and replace the 15.1 with your version
then do the rest
Thanks! That’s what i missed: changing15.1 to 15.2. All good now.
Hello, thanks for this information. I tried to upgrade, did what is needed with repos and upgraded from 15.1 to 15.2 in init 3 mode with commands: zypper –releasever=15.3 dup –allow-vendor-change –download in advance, but I have free space problem, It was about 38 Gb free before upgrade, after upgrade I had about 24-25 Gb less free space. I use btrfs, I checked the summ of all files, I checked snapshots sizes, there was not any file or folder with such size, only free space was less. I tried then to upgrade to 15.3 and upgrade failed, at end I had no free space for installing last some hundred packages. I want upgrade and save my all settings, I choose online upgrade, while I am not sure if I will keep my settings with DVD upgrade. Is Opensuse really designed for upgrade without problems???? Need I every time add +25 or +30 Gb space to root partition after upgrading to next version? What you think, what can be the reason, what to do? And I answered many annoying questions during the install. I dream about 1 klick upgrade with 0 problems and risks, but become stress each spring with new versions. I want restore 15.2 from snapshot and try again, but I not know how solve free space problems? Have you any idea?
