Screenshot of error
I am running [ Android Studio 2.3 Build #AI-162.3764568, built on February 24, 2017 JRE: 1.8.0_112-release-b06 amd64 JVM: OpenJDK 64-Bit Server VM by JetBrains s.r.o] on Ubuntu 16.04. From last few days android studio gives me error on trying to update. I have no idea how to fix this.
I ran the Android studio as administrator and then it worked as it is a permission issue.
