to type special characters in the terminal you need to use the compose key
To configure the compose key on Ubuntu, you need to install dconf and you can find the setting
in the package dconf/org/gnome/desktop/input-source/xkboptions
From Ubuntu 14.04
dconf → org → gnome → desktop → input-sources → xkboptions
e.g. to set the Alt Gr key as compose:
Okay, a few things to note here:
Why are your saves under root? Don't run Minecraft with sudo, and then it should be stored in your home directory.
~ is a shorthand for your home directory. The command cd ~/root does not make any sense.
Your command should be formatted differently. Try running cd ~/Downloads and then java -jar Minecraft-Installer.jar.
Reinstallation does not always help. Create the directory '03@C7:8' in the home directory, and inside this directory create the file 'ync', where you need to write the launch configuration, which is located in the launcher itself (the file manages to be created before the error). I'm use TLauncher and configuration file looks like this:
# TLauncher ...
Get your Java path using the command
The following is a possible output depending on your default Java version
java: /usr/bin/java /usr/share/java /usr/lib/jvm/jdk1.8.0_241/jre/bin/java
Maven need to pick the Java location (home) so you can export the Java path using the following command
The reason why its crashing is because of java 11. you need to install java 8 and under and everything should be fine. here's a post on how to do it: Downgrading Java 11 to java 8?.
and if that doesn't work go and try a youtube video on how to do it.
Filing this under "Who Knew?" on Stack Exchange we have a sister-site called Arcade where your question has an answer:
Is it safe to close Minecraft's multiplayer server?
On our sister-site Unix & Linux there is this answer:
Minecraft server startup/shutdown with systemd
This will probably suit your needs better.
Seems to make sense to backup the world before shutting down the screen session.
I would think this would help:
First, try installing the Forge "Installer" .jar instead of the "Universal" .jar. You can download the Installer from Forge, make sure you're selecting the "Installer" option, not "Universal":
If that still doesn't help and you see the same error, you could try manually downloading the libraries required here:
MinecraftForge needs java 8 and you have 9 or higher. Try installing java 8 and use it. If you don't get it work with the default launcher i'd recommend MultiMC. There you can set the java installation in preferences/java and installation of forge is much easier.
