I am building a Kivy into a Android app using buildozer and I am running into a error. When I type buildozer -v android debug I run into the following error.

#sdkmanager path "/home/.../.buildozer/android/platform/android-sdk/tools/bin/sdkmanager" does not exist, sdkmanager is notinstalled

How can solve this problem.
Note: I am using the Windows virtual Linux terminal (Ubuntu)
So what is basically happening is that buildozer is not finding the sdk manager. There are two ways to tackle this problem. First you can download the SDK tools and unzip it in the folder. Second is to start afresh. Delete all the folders created during the build via the terminal using this command rm -rf folder_name. Then build the app again. This will cause the packages to be downloaded again.
