Hi, I would like to start to do the Kotlin Koans, and I messed with IntelliJ to try to get it to work, and removed the Kotlin SDK, and now I can't re-add it. Any solution to this?

I’ve never tried to do that. But in your second screenshot, you have selected “Installed”. Switch to “Marketplace” to see installable plugins.

I performed a clean re-installation:

rm -rf .IntelliJIdea2018.*
sudo rm -rf /opt/JetBrains/apps/IDEA-U/
rm -rf ~/.local/share/applications/jetbrains-idea.desktop ~/.local/share/applications/jetbrains-studio.desktop

I also uninstalled IntelliJ from the Jetbrains toolbox, rebooted, and re-installed IntelliJ from the Toolbox. I reinstalled the JetBrains academy plugin, and restarted the Koans, and now it works.
