I would run that command with the additional --releasever=43 option.
Before doing that I would run df -h and verify that /boot is not full or nearly so. If /boot fills up it prevents a complete install of the newer kernel.
I also would remove all the wine packages since that was one of the things that you got a message about, and there has been quite some time with many different bug reports about not being able to upgrade from f42 to f43 when wine is installed. sudo dnf remove wine* --noautoremove should do that properly. If you need to use wine it can be reinstalled after the upgrade completes properly. There is a related common issue topic.
Note that the recommended method for upgrading versions is shown here.
The software manager hides any messages and may or may not do the upgrade properly. Users can end up in your situation with no clue as to what may have failed and caused the problem. The cli method using dnf provides messages and tells the user of problems before the upgrade is actually performed.
