After the rename of the KDE5 packages from
<packagename> to
<packagename>5, you still have the outdated old packages in your repositories, e.g.:
pacman -Si kioRepository : world
Name : kio
Version : 5.110.0-2
[...]
pacman -Si kio5Repository : world
Name : kio5
Version : 5.111.0-1
[...]
The old packages are at version 5.110.0 and thus outdated. And they are obsolete.
I suggest you delete them from the repositories.
Regards!
