Minecraft Forums

I just install Ubuntu Mate, I try to run Minecraft and get this error message:

FATAL ERROR: net.minecraft.bootstrap.FatalBootstrapError: Unable to download while being forced
at net.minecraft.bootstrap.Bootstrap.execute(Bootstrap.java:95)
at net.minecraft.bootstrap.Bootstrap.main(Bootstrap.java:381)

you can find the full Bootlog here: http://pastebin.com/xJsG70Kj

From reading the bootlog I can determine that it is something to do with my Internet and is probably something blocking it but I can't seem to find any firewalls.

Your java installation is missing the keystore / ssl certificates. On some linuxes this is a separate package that must be installed.

On Ubuntu it is ca-certificates-java

My Internet works fine for most things but I think you may be right, my computer doesn't connect to steam store either but I have no idea what the problem is, please help??

None of the above answers helped so I tried installing the Windows version with WINE, which seemed to work fine until I tried to join a server which resulted in a crash and an error message and then every time I try to log on it comes up with the same crash.

Here is what shows up:

Please help with either issues, I will be putting up another post for just the WINE issue

I have been informed that the above was a stupid thing to try, and I have also realised that one of my comments did not go through.

I tried sudo apt-get install ca-certificates-java and sudo apt-get install openjdk-8-jre-headless (apparently this installs ca-certificates-java) and both said they were already installed

... your earlier log shows Oracle java. Whatever you do you need the certificates that match the java you are trying to use.

Maybe you have multiple java's and one will in fact work as a result of what you've done, just not the one you are using.

I am using OpenJDK, I navigate to the directory, right click on Minecraft.jar, hover my mouse over Open With, then click OpenJDK Java 8 Runtime, I have tried installing the Java from Oracle but I am not sure how to run Minecraft with it, should I remove the oracle Java?

Can't hurt, and might solve your problem.

Don't use OpenJDK. Mojang recommends Oracle JDK. If you have the Oracle JDK installed, you should set it as your main java alternative. Then, make sure java -version works. You can launch the JAR via command-line using java -jar.

I was previously installing Oracle JRE, so I installed Oracle JDK and then ran

wget http://webupd8.googlecode.com/files/update-java-0.5b

chmod +x update-java-0.5b

sudo ./update-java-0.5b

I then selected the Oracle JDK and it made it the main java alternative like Swatcommander said I should do.

I ran Java -jar /home/****/Desktop/Minecraft.jar and everything worked perfectly

Thanks to everyone who helped me out
