Bug Can't add transitions to animations

There should be an option in the right-click drop-down list to add transition in the animator, but there isn't for some reason. Here's a screenshot of it:



Also, is there any other way to add a transition? Because as you can see, I can't do it the way I normally do.

 

This was fixed in the second available build, we are now testing the third one: http://forum.unity3d.com/threads/unity-on-linux-release-notes-and-known-issues.350256/#post-2298239

 

Thanks!
