Keystore file does not exist: /root/.android/debug.keystore for ubuntu

Need google+ sign in for my phonegap application for that I want to generate Certificate SHA-1.I run
keytool -exportcert -list -v \
-alias androiddebugkey -keystore ~/.android/debug.keystore
the command to generate Android Signing Certificate SHA-1, but it gave an error
Keystore file does not exist: /root/.android/debug.keystore
so I search for that file using find ~ -name "debug.keystore" but my search result is empty.
I also tried below command
keytool -genkey -alias myKey -keystore store.jks
keytool -selfcert -alias myKey -keystore store.jks
but i didn't found Android Signing Certificate SHA-1

keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android
Try this command. Your debug keystore is always present in /home/<username>/.android and ~ is just a shorthand for /home/<username>.
If your SDK is installed properly, there should be no issues in running that command. Otherwise, we'll need some more information to find and fix the issue.
If PhoneGap/Meteor has its own set of android bundles, you might want to try something on these lines
keytool -list -v -keystore ~/.meteor/android_bundle/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

You don't have to use the debug certificate, just create a new certificate by following this tutorial and use it to sign your debug and release versions of the app.

Convert an existing Keystore to an android debug keystore for eclipse

Sometimes it might be handy to use an existing keystore in eclipse (Android -> Build -> CustomKeystore) to build from within eclipse.
The Eclipse plugin does not allow to change the keystore password, key-alias and key password though.
Is there a way to convert an existing keystore to match the default requirements?

The following keytool commands should do the trick. There definitly is a simpler way, but it already took enough time figuring this one out :)
keytool -genkey -v -keystore debug.keystore -alias androiddebugkey -keyalg RSA -keysize 2048 -validity 10000
keytool -delete -alias androiddebugkey -keystore debug.keystore
keytool -importkeystore -srckeystore src.keystore -destkeystore debug.keystore
keytool -changealias -alias srcalias -destalias androiddebugkey -keystore debug.keystore
keytool -keypasswd -alias androiddebugkey -keystore debug.keystore
This creates a new keystore and imports an existing key from a source keystore
keystore. src.keystore -> your source keystore that will be used
srcalias -> your source alias you're currently using
passwords are entered on cmdline
use 'keytool -list -keystore debug.keystore' to check the result.

Very useful information, should be voted up. I wrote a small batch file basing on Icyerasor's answer:
keytool -genkey -v -keystore debug.keystore -alias androiddebugkey -keyalg RSA -keysize 2048 -validity 10000 -storepass android -keypass android -dname "CN=kristjan sander, OU=Unknown, O=bitspinners, L=tallinn, ST=Unknown, C=ee"
keytool -delete -alias androiddebugkey -keystore debug.keystore -storepass android
keytool -importkeystore -srckeystore keystore.jsk -srcstorepass qwerty -destkeystore debug.keystore -storepass android
keytool -changealias -alias bitspinners.eu -destalias androiddebugkey -keystore debug.keystore -storepass android -keypass qwerty
keytool -keypasswd -alias androiddebugkey -keystore debug.keystore -storepass android -keypass qwerty -new android
keytool -list -keystore debug.keystore -storepass android

keytool Error for Map API Key

How to publish the Apk file with signed key for Map,
Am Getting Error as Follows in CMD
C:\Program Files\Java\jdk1.7.0_21\jre\bin>keytool -list -v -keystore D:\Shankar
Completed Project\Mandate Project\keystore -alias mandatehandbook
Illegal option: Completed
keytool -list [OPTION]...
Lists entries in a keystore
Options:
Use "keytool -help" for all available commands

Put quotes around the keystore path. Your shell is confused by the space in the pathname.
keytool -list -v -keystore "D:\Shankar Completed Project\Mandate Project\keystore" -alias mandatehandbook

debug keytool example:
keytool -list -v -keystore "D:\Users\%your name%\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

how i can get MD5 hash in jdk.7.o?

when i try to get MD5 hash by using
C:\Program Files\Java\jre7\bin>keytool -list -alias androiddebugkey -keystore "C:\Users\learnwhat.android\debug.keystore" -storepass android -keypass android
only get SHA1 hash i need MD5 hash to in goole Map api key sing up. how i can get MD5 hash in jdk1.7.0_09?.

Add -v with command if you are using jre7 for getting MD5 hash for Google Map. this command return you both MD5 and SHA1 :
C:\<YOUR_JDK_PATH\bin>keytool -v androiddebugkey -keystore "C:Users\YOUR_NAME\.android
\debug.keystore" -alias alias_name -storepass android -keypass android

using the following command:
keytool -v -list -alias androiddebugkey -keystore debug.keystore
-v will force keytool generate md5, sha1, sha256
