These are the steps which solved my problem:

```
Move to java directory (where jre was installed on my server)
```
cd /path/to/jre/bin

Use     keytool -genkey -alias mypassword -keyalg RSA

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

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

find your jre location   sudo find   -name jre And then    sudo update-alternatives --install  usr bin keytool keytool  opt jdk  lt jdk verson gt  jre bin keytool 100

User · Answer

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
