Myopenhab shows offline

Linux beginner here… just dug out that post searching for a solution to my offline hab…
Can someone explain me how to do the quoted stuff? Its viable for a Pi?

This is an explanation of the command given:

sudo vi /etc/apt/sources.list

You need to edit the file called “sources.list” in the folder “/etc/apt/”. To edit the file you will need to have root access so you need to use the “sudo” command to give your user root privileges. “vi” is the name of the text editor. The command will open “sources.list”. You need to add the lines below to this file. This can be done by moving your cursor to the last line. Press Ctrl+A. This will allow you to append to the end of the last line. Press Enter and copy the lines to the file. When done press Esc twice, then the “:” (colon) followed by “wq” (lower case). This will save the file and exit the editor.

deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu trusty main

Now run the other commands as shown in the previous posts and you should be good to go.

If you still struggle to follow I would suggest that you view a few Debian Linux beginners tutorials on Youtube. Best of luck yo you.

I was really struggling with this problem, but it turned out to be the Java-version. For my version @Manbearpig73’s solution didn’t work, instead I’ve used https://gist.github.com/ribasco/fff7d30b31807eb02b32bcf35164f11f and it worked like a charm.
