Error saying Connection failed when trying to install java jdk on slave VM

Question

Hey, I have installed jenkins and java JDK on my master VM, now I'm trying to install it on the slave VM but I'm ending up with an error. I've used the same commands on my slave VM as on the master. The problem is, it worked on the master and didn't work on the slave. Where am I going wrong?

Command that produced this error:

sudo apt-get install default-jdk

Hey @Ali, I went through the error and there are two possible reasons for this error:

• either your VM is not connected to the internet

• or it's unable to connect to the default jdk

Check your internet connection, if not connected, connect it to the internet and try the same command again. 

If that doesn't work, download the openjdk-8-jdk instead of the default one. Execute the following commands:

sudo apt-get upgrade
sudo apt-get update
sudo apt-get install openjdk-8-jdk
