Thank you so much for this information. I am completely linux illiterate but was able to use your post and another about upgrading to JDK 16 to do this from the command line using wget (first time ever) for those in a similar situation, here is how to do it from the CLI:
apt remove java-common
wget https://download.java.net/java/GA/jdk17.0.1/2a2082e5a09d4267845be086888add4f/12/GPL/openjdk-17.0.1_linux-x64_bin.tar.gz
tar -xf openjdk-17.0.1_linux-x64_bin.tar.gz -C /opt/
ln -sf /opt/jdk-17.0.1/bin/java /usr/bin/java
Thanks so much everyone, especially @NukesDidAnime @sneezing-undertone-d and @hexparrot
My kiddo will be happy that his dad figured out how to get our server back up and running
