Download Oracle Java From The Terminal With wget
By using Webupd8 Team’s PPA repository, Java 8 can be installed using apt command. But first, the repository needs to be added to your Ubuntu system. Sudo add-apt-repository ppa:webupd8team/java sudo apt update. When the repository is added, install Java 8 by executing the following command in your terminal. Sudo apt install oracle-java8. I want to install a dmg file on a remote server. All I have is an ssh access. Since a DMG is a disk image, I tried to mount it, but mount does not seem to recognize its format. File says my dmg file is a VAX COFF executable.

Oracle have a very restrictive license that applies to most of their software downloads which prohibits you from distributing the binaries yourself. What this means, for example, is that you could not download the Java binaries and upload them to your own APT repository for others to use.
There are a few workarounds that exist to help making this install easier, but here we’re going to look at downloading the Java runtime environment (JRE) binaries and installing them all from a command line.
Use wget to download the binaries, so make sure that’s available on your system. If it isn’t, simply apt-get install wget.
One of the important things to note is that the Java version changes over time and therefore the links and commands below may need to be changed to ensure you’re always getting the latest version. Check out the Java Download Page to make sure you have the latest.
I’m using an minimal version of Debian that doesn’t have the worlds Certificate Authorities installed and therefore wget gives me an error:
The fix is to either install the correct CA certificate on the machine or add the no-check-certificate switch to wget to avoid checking the certificate:
Once you have the Java archive downloaded you’ll need to create a target folder and extract the downloaded archive with tar:

The last couple of steps are to tell your OS to use the Java binaries you’ve just moved into place.
Running anything in Java, or using the -version switch should now use your newly installed binaries.
After upgrading to a newer version of Mac OS X (Yosemite 10.10 and El Capitan 10.11) or macOS (Sierra 10.12 and High Sierra 10.13), you may end up getting an annoying new pop-up message whenever you start your computer. It says, “To use the java command-line tool, you need to install a JDK.” It asks you to click “More Info” and visit the JDK (Java Developer Kit) download website.
The reason you’re receiving this message is due to the removal of Java support in newer versions of OS X for security reasons. Older software such as Adobe Photoshop and Illustrator requires legacy Java support. Without a compatible Java command-line tool for these software, you’ll get this pop-up every time you turn on your Mac computer.
When you visit the download website to update Java, you find that the issue isn’t resolved! You’re still getting the same pop-up. This isn’t a complicated issue to fix, but it is an indirect one. The problem is that you’re not being routed to the correct download website when you click “More Info.”
Apple could have remedied this issue by programming the “More Info” button to direct you to the right fix. Here are the steps you can take to finally rid yourself of this pop-up:

- Mount the .dmg disk image file and install Java 6 runtime for OS X.
- Restart your Mac and enjoy the absence of this Java command-line tool error pop-up!
