I'm supposed to play a bit with Linux server for my training and I just thought about installing a Minecraft server on the server. I need java for that. I can't handle that somehow.
I've already tried that: https://www.digitalocean.com/community/tutorials/how-to-install-java-with-apt-get-on-ubuntu-16-04
At what point does your attempt fail and what error message will be output?
You also use Ubuntu 16.04?
Is actually enough?
Install Java:
apt install openjdk-11-jre
Set JAVA_HOME:
echo "export JAVA_HOME =" $ (readlink -f / usr / bin / java | sed 's: bin / java::') ""> /etc/profile.d/openjdk.sh
Run both commands as root.
Get the following error messages:
E: Could not open lock file "" - open (13: Permission denied)
although I'm logged in with the only admin user and actually have the rights
Ok, java has now installed differently
Do you still have a different package management tool somewhere, e.g. Synaptics, run? Then do that and then the steps again.
You are only root when id -u 0 comes out.
Have java now installed like this:
sudo apt-get install default-jre
and btw, how can I actually uninstall programs?
Sudo apt remove $ PACKAGE (keeps the configuration files) or
sudo apt purge $ PACKAGE (also removes the config files)
Thanks
Install Java on Ubuntu Server on xfce4 interface?
That's the first mistake, on a server you do not need a graphical interface. The only opens additional entrance gates and brings no benefit.
I should play around for my education a bit with Linux server
A server is not a toy and if you want to learn this should not be public.
I've already tried that
At which point, so with which command do you not get further?
Linux Hase
