If you are working on signing your Flutter App by following this guide Build and release an Android app and run in to this error  I hope this answer helps you  In my case I changed the path to store my key jks  This happened to me because I there was an existing file in that path  keytool -genkey -v -keystore   key jks -keyalg RSA -keysize 2048 -validity 10000 -alias key  This command stores the key jks file in your home directory  To store it elsewhere  change the argument you pass to the -keystore parameter  In my case  keytool -genkey -v -keystore  Users Y Desktop X key jks -keyalg RSA -keysize 2048 -validity 10000 -alias keyYour  i e Y - Username and X - folder name Then you will be prompted to Enter keystore password   and Re-enter new password   Here you can use whatever password you want  However  keep the keystore file private  don   t check it into public source control

From your description I assume you are on windows machine and your home is abc So Now   Cause When you run this command keytool -genkey -alias tomcat -keyalg RSA because you are not specifying an explicit keystore it will try to generate  and in your case as you are getting exception so to update  keystore C  users abc gt  keystore and of course you need to provide old password for  keystore while I believe you are providing  your version  a new one   Solution  Either delete  keystore from C  users abc gt  location and try the command  or try following command which will create a new xyzkeystore  keytool -genkey -keystore xyzkeystore -alias tomcat -keyalg RSA   Note  -genkey is old now rather use -genkeypair althought both work equally
