### Upgrading OpenSUSE Leap online ### |
|
|
|
|
|
I use SUSE on my computer since SuSE Linux 9.1 (yes, I'm that old). Since a |
|
couple of years, I perform online upgrades - they are much more convenient |
|
than the CD- or DVD-based upgrade process. Upgrading OpenSUSE used to require |
|
changing all the registered repositories so they point to the next version, |
|
allowing YaST (zypper) to fetch the new packages. It is only recently that I |
|
learned about a neat trick to avoid this hassle: instead of hard-coding the |
|
OpenSUSE version in the repository URL, use the $releasever variable! |
|
|
|
Specifically, in YaST / Online Repositories, instead of such repos: |
|
|
|
http://download.opensuse.org/distribution/leap/15.1/repo/oss/ |
|
http://packman.inode.at/suse/openSUSE_Leap_15.1/ |
|
|
|
Use these: |
|
|
|
http://download.opensuse.org/distribution/leap/$releasever/repo/oss/ |
|
http://packman.inode.at/suse/openSUSE_Leap_$releasever/ |
|
|
|
The day-to-day working of such repositories is the same, but when time for |
|
upgrade comes, there is no need any more to change all your repositories. |
|
The online upgrade becomes a simple, almost enjoyable 4-steps process: |
|
|
|
1. Make sure your distribution is up-to-date |
|
|
|
2. Refresh zypper using the n+1 version of your SUSE system: |
|
# zypper --releasever=15.2 ref |
|
|
|
3. Perform the distribution upgrade: |
|
# zypper --releasever=15.2 dup |
|
|
|
4. Reboot |
