Hi,

I wanted to post a comment to this thread, but it's already been closed.

I have the same issue as the OP, but when I try the "chosen
answer"

> It looks like this happens when the alias in the distribution tab does not match the keystore alias. To check your keystore alias, type 'keytool -list -v -keystore android.keystore' in a terminal window (where android.keystore is the name of your keystore) and you'll find the alias next to the 'Alias name' entry in the output.

I get the following error message:

> sibrand@piggy:~/MobileDev/Titanium Developer-1.2.1$ keytool -list -v -keystore android.keystore
keytool error: java.lang.Exception: Keystore file does not exist: android.keystore
java.lang.Exception: Keystore file does not exist: android.keystore

at sun.security.tools.KeyTool.run(KeyTool.java:194)
at sun.security.tools.KeyTool.main(KeyTool.java:188)

I then tried to do "apt-get install keytool", which responded:
> E: Couldn't find package keytool

What to do?
