If you are not using openjdk, use the below commands to set your keytool.

sudo update-alternatives --install "/usr/bin/keytool" "keytool" "/usr/lib/jvm/java8/jdk1.8.0_251/bin/keytool" 1

AND

sudo update-alternatives --set keytool /usr/lib/jvm/java8/jdk1.8.0_251/bin/keytool

This worked for me!

These are the steps which solved my problem:

  • Search the path where my java was installed 

    find / -name jre

  • Move to java directory (where jre was installed on my server)

    cd /path/to/jre/bin

  • Create SSL certificate with keytool command

    ./keytool -genkey -alias [mypassword] -keyalg [RSA]

If the jre is installed on your machine properly then look for keytool in jre or in jre/bin

  1. to find where jre is installed, use this

    sudo find / -name jre

  2. Then look for keytool in path_to_jre or in path_to_jre/bin

  3. cd to keytool location

  4. then run ./keytool

  5. Make sure to add the the path to $PATH by

    export PATH=$PATH:location_to_keytool

  6. To make sure you got it right after this, run

    where keytool

  7. for future edit you bash or zshrc file and source it

You could also put this on one line like so:

/path/to/jre/bin/keytool -genkey -alias [mypassword] -keyalg [RSA]

Wanted to include this as a comment on piet.t answer but I don't have enough rep to comment.

See the "signing" section of this article that describes how to access the keytool.exe without changing your working directory to the path: https://flutter.dev/docs/deployment/android#signing-the-app

Note that they say you can type in space separated folder names like /"Program Files"/ with quotes but I found in bash i had to separate with back slashes like /Program\ Files/.

Keytool comes with your Java library. So you have to execute the Keytool command from your /Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/jre/bin directory. Or you can add JAVA_HOME to your environmental variables (Windows) or ~/.bash_profile (Linux)

If you are looking for keytool because you are working with Android studio / Google Firebase, there is a keytool bundled with Android Studio. After extracting the zip file, the path to keytool is android-studio/jre/bin.

It seems that calling sudo update-alternatives --config java effects keytool. Depending on which version of Java is chosen it changes whether or not keytool is on the path. I had to chose the open JDK instead of Oracle's JDK to not get bash: /usr/bin/keytool: No such file or directory.

You tried:

sudo apt-get install oracle-java6-installer --reinstall

and:

sudo update-alternatives --config keytool

Ensure jre is installed. 

cd /path/to/jre/bin/folder

As keytool file is present in the bin folder of jre, give path till bin as in the command above.

Then you can do:

keytool -genkey -alias aliaskeyname -keyalg RSA -keystore C:\mykeystore

The additional option -keystore will help you to specify the path where you want the generated self signed certificate.
