Keystore not working on unity 2017.1 - unity3d

Question

our team started to work on an old project to fix bugs and add new features. But we have a problem on the keystore file. After project updated to Unity 2017 we started to get an error that says:
CommandInvokationFailure: Failed to sign APK package.
/Users/work/Library/Android/sdk/build-tools/26.0.2/apksigner sign --ks
"/Users/work/Desktop/work game/MAIN/game.keystore" --ks-pass
pass:"***" --ks-key-alias "***" --key-pass pass:"***" "/Users/work/Desktop/work/game/MAIN/Temp/StagingArea/Package.apk"

Tried with different JDK versions. Changed keystore name, its destination but still same result. The same keystore works on Unity 5.6 perfectly. The update should be published soon. Solving the problem as soon as possible is crucial for us.

Answer 1

Under Publishing Settings, try changing the Build System to Gradle (New) instead of Internal (Default).
If above not work try updating Android Studio and also update the android SDK.
If above not working try below steps
1) just open https://developer.android.com/studio/index.html
2) scroll down to the bottom of that page
3) go to downloads
4) scroll down to the bottom of that page
5) find Windows "tools_r25.2.3-windows.zip" download and unzip it
5) find MacOSX "tools_r25.2.3-macosx.zip" download and unzip it.
6) In the SDK path replace the tools folder.
