I got the following error when running sudo dnf upgrade --refresh:

Problem: package kalzium-18.04.3-1.fc28.i686 requires libAvogadroCore.so, but none of the providers can be installed - cannot install both avogadro2-libs-1.91.0-1.fc28.i686 and avogadro2-libs-1.90.0-15.fc28.i686 - cannot install both avogadro2-libs-1.90.0-15.fc28.i686 and avogadro2-libs-1.91.0-1.fc28.i686 - cannot install the best update candidate for package kalzium-18.04.3-1.fc28.i686 - cannot install the best update candidate for package avogadro2-libs-1.90.0-15.fc28.i686 ...

I have avogadro2-libs-0:1.90.0-15.fc28.i686 installed. kalzium-18.04.3-1.fc28 requires libAvogadroCore.so, libAvogadroIO.so, libAvogadroQtGui.so, libAvogadroQtOpenGL.so, libAvogadroQtPlugins.so, libAvogadroRendering.so. avogadro2-libs 1.91.0-1 provides those libraries but with the .1 suffix such as libAvogadroCore.so.1. kalzium might need to be rebuilt to use those new library names.

@than @jreznik @rdieter

kalzium needs to be rebuilt against new avogadro2-libs buildroot override for f28.

works

I upgraded to avogadro2-libs-1.91.0-1 and kalzium-18.04.3-3 without the dnf error I mentioned previously. kalzium-18.04.3-3 doesn't show the top two menu rows and the information panel on the left and legend on the bottom as shown in its documentation https://docs.kde.org/stable5/en/kdeedu/kalzium/quick-start.html

kalzium-18.04.3-3 shows just the periodic table view and the bottom row with the element and mass. I tried downgrading to avogadro2-libs-1.90.0-15 and kalzium-18.04.3-1, but kalzium's interface was still missing those parts. kalzium-18.04.3-1 did show all the parts about 6 days ago when I got the dnf error and I was using Qt 5.10.1. I upgraded to Qt 5.11.1 on Aug 28. I guess that a problem with Qt 5.11.1 might be the reason for these missing interface parts.

I installed avogadro2-1.91.0-1 and it runs fine with basic testing. avogadro2-1.91.0-1's Help - About window shows Version: 1.90.0 AvogadroLibs Version: 1.91.0 Qt Version: 5.11.1 and the top window bar shows Untitled - Avogadro 1.90.0. I'm unsure if the interface version should be 1.90.0 or 1.91.0.

It's a known bug.

Given that you already reported the avogadro interface version bug, I'll give +1 for avogadro2 by itself. I'm unable to test kalzium's usage of avogadro2-libs-1.91.0-1 because the missing parts in kalzium's interface with Qt 5.11.1 include the molecular editor part which I guess uses avogadro-libs. I filed the following bugzilla entry about the kalzium issues to inform its maintainers in more detail. https://bugzilla.redhat.com/show_bug.cgi?id=1625282

The kalzium interface issue was because of abnormal configuration settings in ~/.config/kalziumrc which I fixed by renaming that file. All the parts of kalzium interface are visible to me, and those I've tested are functional. I opened a few molecules in kalzium's molecular editor which I suppose uses avogadro2-libs which all appeared correctly. So I'll give +1 for kalzium and its use of avogadro2-libs.

Glad to see your positive feedback @mattf . These updates are now managed by @rdieter.
