Good evening, morning or day to you, fellow Ubuntu users!

I have encountered a problem when trying to run Minecraft on Ubuntu MATE 18.04. I followed the instruction given on the website How to Geek How to Install Minecraft on Ubuntu or Any Other Linux Distribution, adding the repository for Oracle Java 8 etc. After downloading Minecraft.jar from www.minecraft.net I executed the file (java -jar Minecraft.jar), but...it didn't go exactly as expected. The output I got was:

Downloading: https://s3.amazonaws.com/Minecraft.Download/launcher/launcher.pack.lzma Exception: javax.net.ssl.SSLException: java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty

Downloading: https://s3.amazonaws.com/Minecraft.Download/launcher/launcher.pack.lzma (try 2/10)

...and so on.

Do you perhaps know how to solve this problem?

This information, displayed while launching Minecraft, may be of use:

System.getProperty('os.name') == 'Linux' System.getProperty('os.version') == '4.15.0-20-generic' System.getProperty('os.arch') == 'amd64' System.getProperty('java.version') == '1.8.0_171' System.getProperty('java.vendor') == 'Oracle Corporation' System.getProperty('sun.arch.data.model') == '64'

Any advice on this topic will be appreciated! Thank you in advance!

/Robert.

I had this same exact problem. What I did to fix it was:

sudo apt-get update & sudo apt-get install ca-certificates-java
sudo update-ca-certificates -f

Go to the Java website and download the .tar.gz linux file. Extract the file from the archive:

jdk-10.0.1_linux-x64_bin.tar.gz/jdk-10.0.1_linux-x64_bin.tar/jdk-10.0.1/lib/security/cacerts

Copy the file to 

/etc/ssl/certs/java/cacerts

Just install Minecraft from Snap store- 

sudo snap install mc-installer

Start the app after installation.
