When I go into the SDK manager in Android Studio, and I go to the tab that says SDK Update Sites, It says \"unknown error\" next to Google Inc. (x86 System Image). I can never u
I felt super stupid. I landed on this page after googling the error. I tried the Invalidate Cache thing. didn't work. Looked deeper into the error and tried doing as it said, manually removing the system image it was trying to overwrite. I couldnt. It was in use. wtf. oh, the emulator i had going slipped past me, it didn't shutdown with the android studio restart and updating.
Closed the emulator and the upgrade finished successfully instantly.
Check for instances of the system image file running, the file from folder C:\Users\NAME\AppData\Local\Android\Sdk\system-images\android-29\google_apis\x86
