Hey there, let's break down what's causing your installation issues and fix it step by step.

The Core Problem #

You're attempting to install the ARM64 version of JDK 8 (jdk-8u161-linux-arm64-vfp-hflt.tar.gz) on an Ubuntu 17.10.1 VM running in VMware Workstation Pro. Almost certainly, your Ubuntu VM is using the standard x86_64 (amd64) architecture—ARM64 binaries won't run on x86_64 systems, which is why your setup is failing.

Step 1: Confirm Your System Architecture #

First, verify your VM's architecture to be sure. Run this command in the terminal:

uname -m

If the output is x86_64, you have an amd64 system and need the x64 version of JDK 8.

Step 2: Clean Up the Incompatible JDK Setup #

Let's remove the incorrect ARM64 JDK and its alternative configurations:

1. Remove the java alternative entry:

   sudo update-alternatives --remove java /usr/lib/java/jdk1.8.0_161/bin/java
   

2. Remove the javac alternative entry:

   sudo update-alternatives --remove javac /usr/lib/java/jdk1.8.0_161/bin/javac
   

3. Delete the ARM64 JDK folder:

   sudo rm -rf /usr/lib/java/jdk1.8.0_161
   

Step 3: Install the Correct x64 JDK #

1. Download the x64 version of JDK 8: jdk-8u161-linux-x64.tar.gz (from the official archive you used earlier, just select the x64 package).
2. Extract the tar.gz file and copy the resulting jdk1.8.0_161 folder to /usr/lib/java (same directory you created before).
3. Reconfigure the alternatives system with the correct binaries:

   sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/java/jdk1.8.0_161/bin/java" 1
   

   sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/java/jdk1.8.0_161/bin/javac" 1
   

Step 4: Verify the Installation #

Check if the setup works by running these commands:

java -version

javac -version

You should see output confirming JDK 1.8.0_161 is active.

Note: If You Need ARM64 Environment #

If you actually intended to run an ARM64 system, you'll need to create an ARM-based VM in VMware Workstation Pro (note: older versions of VMware may have limited ARM support, and Ubuntu 17.10 is end-of-life—consider using a newer Ubuntu ARM release for better compatibility).
