For weather station management software, weewx, I have a problem displaying weather information web pages.
I posted my error log on the weewx support site. I received a response from the creator of the software, Tom Keffer, who informed me that the installation I made with the weewx repository also installed the Pillow library in version 10 which is incompatible with my version (4.10 of weewx).
I need Pillow version 9.5
I did some research with zypper but only versions 10.0.1 are available.
I couldn’t find a zypper command to do a downgrade.
How do I downgrade the Pillow library to version 9.5?
You cannot. You may try to look at /history - openSUSE Download if previous version is still available from some older snapshot, but if any other installed package is built against and requires Pillow version 10, you will get conflicts.
If running this specific package is important to you, you may consider either installing Leap (for which weewx repository does exist) or running Leap container with this software.
