Just a heads up, in case this is of any significance. I tried to install libkdecorations2-5v5_5.19.5-4_amd64.deb manually (it is not yet proposed by apt, maybe for good reasons), and got the following warning.
The following packages will be REMOVED: breeze kde-plasma-desktop kinfocenter kwin-common kwin-style-breeze kwin-x11 plasma-desktop plasma-integration plasma-widgets-addons plasma-workspace These do not look like the kind of packages I want to do without! I will wait to see if the upgrade process is smother once the package hits the repositories. I also tried to upgrade to 5.19.5-2 prior to installing 5.19.5-4 and got the same result. Best, Victor
