Minecraft 1.9 Prerelease 6 Ubuntu Installation

Jeb tweeted the links to the 1.9.6 client and server today. The release candidate should be out Sunday, so find those bugs! If you missed them, here they are:

• Client
• Server

Note: This is outdated. For the updated client, check this page.
Ubuntu Client Installation:

# Backup your old client, just in case
mv ~/.minecraft/bin/minecraft.jar ~/.minecraft/bin/minecraft.jar.bak
# Download the new one
cd ~/.minecraft/bin; wget http://assets.minecraft.net/1_9-pre6/minecraft.jar
# And play like normal!
minecraft
# If you didn't alias this:
java -Xmx1024M -Xms512M -cp Minecraft.jar net.minecraft.LauncherFrame

And for the Ubuntu-based server installation:

# Stop the server
stopmc
# Or if you haven't followed my tutorials, get to your console (tmux or screen) and type "stop".
# Backups are important!
mv ~/minecraft/minecraft_server.jar ~/minecraft/minecraft_server.jar.bak
# Get the new one
cd ~/minecraft; http://assets.minecraft.net/1_9-pre6/minecraft-server.jar
# Start minecraft again!
startmc
