To fix the issue with the JAVA_HOME environment variable, you can follow these steps:
1. Determine the correct path to your Java installation directory. Usually, it is located in `/usr/lib/jvm` or `/usr/local/java`.
2. Open your terminal and run the following command to edit the bashrc file:
```
nano ~/.bashrc
```
3. Scroll to the end of the file and add the following line:
```
export JAVA_HOME=/path/to/your/java/installation
```
Replace `/path/to/your/java/installation` with the actual path to your Java installation directory.
4. Save the changes by pressing `Ctrl + X`, then `Y`, and finally `Enter`.

```
source ~/.bashrc
```
6. Verify that the JAVA_HOME variable is set correctly by running:
