Dear stackoverflow users:
So far I was working well with kate when I installed it in ubuntu 16.04 as sudo apt-get install kate.
However, some days ago. I got the following error when launching kate: org.kde.kwindowsystem: Could not find any platform plugin
I have tried removing, the app and reinstalling it, deleting the ./kde folder and the same remains.
Do you know how to fix it back to the original configuration? Thank you
I suggest you update your 16.04 installation to a more recent one. Many things improved, and this issue will also be resolved. I don't think this is Kate's fault here.
