CLion: All keyboard shortcuts disabled after update
I just updated from CLion 2.5 to 3.0 and all keyboard shortcuts are now disabled. I can pull down the various menus and see the shortcut mappings displayed, but they are all grayed out. I go to Settings->Keymap and I see all the mappings are still there, but none of them work. I can type so it's not a broken keyboard... Is there a global setting to enable shortcuts? Help! I'm on Ubuntu 16.04.

Hello!
It's strange. Do you see any errors in the idea.log file (Help | Show Log in ...)?
Have you tried to reinstall CLion? For complete reinstallation: uninstall CLion, remove the ~/.CLion2019.3 folder or move it to some other location, install CLion once again and don't import settings during the installation process.
I just reinstalled after completely wiping the previous installation, but the problem persists. For the moment, I'm sticking with CLion 18.2 just to be able to work, but I would like to update! Here's the log starting with the re-installation:
It seems you have settings sharing enabled, is that so? In this case deleting directories doesn't make much sense, unfortunately, since your settings are imported anyway. And I assume the reason of the issue is in the settings.
Please do File | Export Settings and send the archive to clion-support at jetbrains.com.
OK, reinstalled again to export settings. BTW, I'm seeing this on the console terminal:
For some reason, my File menu doesn't have the option to export settings ???
I also do Help->Find Action, search for "Export Settings" and I see it under "File", but it's not. Nuts. Back to 18.

That's because you have settings sync enabled. You need to disable it in order to be able to export settings.
You can export your settings from CLion version that is installed currently, you don't need to update CLion to do that.
