We recently encountered an issue with our Managed package in Summer '17 Sandboxes, not being able to install it in them and I recently read some posts asking how to downgrade Sanboxes or why the install is failing and found out there is a known issue here .
Would someone happen to have further details on what might actually be going on? (Is it safe to assume that this will be fixed rather quickly?)
Here is an excerpt of the error messages reported related to lightning components of the managed package:
