SUMMARY Yesterday (2022-12-17) update failed with error as following: <cut> Package failed to install: Error while installing package: trying to overwrite '/usr/share/applications/kcm_kwindecoration.desktop, which is also in package kwin-common 4 </cut> Seems kwin is broken because doesn't start and because of this no decorations of window. Alt+Tab doesn't work. Win+Tab (switching activities) doesn't work. Anyway use of Plasma is very difficult in this status. pkcon reports: <cut> $ pkcon update Fatal error: Error while installing package: trying to overwrite '/usr/share/applications/kcm_kwindecoration.desktop', which is also in package kwin-common 4 </cut> The try of fixing packages ( apt --fix-broken install ) ends with following error: <cut> Preparing to unpack .../kwin-data_4%3a5.26.4+p22.04+tunstable+git20221218.0019-0_all.deb ...

Run Discover 2. Click "Update All" 3. OBSERVED RESULT Package (I suppose kwin-data) failed to install as in description. EXPECTED RESULT Package, especially kwin should be installed without problem due to this makes that use of Plasma is very difficult SOFTWARE/OS VERSIONS Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.26.80 KDE Frameworks Version: 5.102.0 Qt Version: 5.15.7 ADDITIONAL INFORMATION Affects on X11 and Wayland
Even cannot install alternative desktop environment, and suggested "'apt --fix-broken install" doesn't help. $ sudo apt-get install xfce4 Reading package lists... Done Building dependency tree... Done Reading state information... Done You might want to run 'apt --fix-broken install' to correct these.

Below please find my workaround/fix: $ sudo dpkg --force-all -i kwin-data_4%3a5.26.4+p22.04+tunstable+git20221218.0019-0_all.deb kwin-common_4%3a5.26.4+p22.04+tunstable+git20221218.0019-0_amd64.deb Please fix packages.
