    Question Easiest way to install Minecraft in Kubuntu 20.04

    My nephew has been attempting to install Minecraft 1.16.1 onto my desktop PC running Kubuntu 20.04, but each time we attempt to launch the Minecraft game, it displays a message stating "Please wait" but it never actually loads the game.

    I created a user account for my nephew, and made his account part of the sudo group, but this did not seem to make a difference. Does anyone know what we are doing wrong?

    Any advice is greatly appreciated.

    Did you remember to install Java?

    Nope, I sure didn't! Guess I'll give that a try on Friday when he comes back. Thanks for the info.

    isn't open JDK installed by default?

    installing minecraft on Ubuntu:

    https://linuxconfig.org/how-to-insta...al-fossa-linux

    if you need oracle java it get's more complicated now to install it and to maintain it up to date.
    1. you need to sign up to oracle and agree to terms and conditions.
    2. each time when there is an update, you need to manually download it and move it to folder accessible by root only. then perform the update.

    go down to oracle java:
    https://www.digitalocean.com/communi...n-ubuntu-20-04

    i would suggest you try with openjdk first.
    Read the easy to understand, lots of pics Ubuntu manual.
    Do i need antivirus/firewall in linux?

    Could be; I really can't remember. I was mostly prodding the OP towards the fact that Minecraft is a Java application, so there needs to be something to run that. I do remember that when I was last setting it up Minecraft itself seemed to do OK with OpenJDK, but OptiFine really needed Oracle Java.

    I've also remembered that somewhere around 1.14-1.15 the original Minecraft.jar stopped working and you needed to switch out to a newer launcher, but I can't remember the symptoms of using the old one. Just that it didn't work.

    Re: Easiest way to install Minecraft in Kubuntu 20.04

    Well, it looks like installing Java allowed me to get Minecraft working on my system, but now I'm wondering about something else related to having this game installed on my PC. I've been doing some reading, and it appears that Minecraft user files can occupy up to an entire gigabyte of space, so now I'm searching for a method to have Minecraft save its data to another partition other than my sda1 partition, where my Kubuntu installation resides.

    According to what I've read, there is a way to configure Minecraft to point to another user directory, once a user profile has been created, but it looks like my problem is going to be that my nephew will have to enter an administrator password each time he wants to mount the partition where his Minecraft user files are being stored.

    I don't really feel like giving him my password, so is there a way that he can mount one of my NTFS without having to enter a password. Also, I his account to be just a regular user account if I can get away with it.

    Any advice greatly appreciated.

    the easiest way is to automount at boot: https://askubuntu.com/questions/1649...unt-at-startup

    this will however, give them access to all NTFS drive.

    if you used linux file system on it, you could assign and mount only a folder. i am not sure this is possible on linux with NTFS.

    for example i put minecraft server on my home server. then i created minecraft user (normla user, no sudo powers or anything like that) that can only acces via SSH their small /home folder and a folder on RAID1 disk that is mounted at boot and only one folder is accessible to this user. it's where minercfat is and where server runs and saves files.

    another option, if you had linux files system, would be to symlink a folder from that system to /home./minecraft of this user


    finally, is 1 GB still a lot in the era of terrabyte (1000GB+) drives?

    Well, I really don't want to give him access to all of my NTFS partitions, so I guess what I will have to do is mount the partition for him each time he comes over, which is usually only once or twice a week.

    BTW, we got Minecraft to work, but I can find anywhere within its settings to make it store data to an alternate location? Any ideas how this works?

    Also, the reason why I'm worried about adding too much to my sda1 partition, is because I usually keep that partition at around 30 Gb in size, that way it is easier/faster to create images of it and to restore them if need be.

    There are lots of things that are set in the launcher rather than in-game; the save location is one of them. Or you can just symlink that user's ~/.minecraft to wherever you want.

    Well, I really don't want to give him access to all of my NTFS partitions, so I guess what I will have to do is mount the partition for him each time he comes over, which is usually only once or twice a week.
    Even using NTFS, which doesn't understand permissions, there's access and there's access. Mounting a partition somewhere at boot and symlinking ~/.minecraft to a directory on it is functionally the same as having ~/.minecraft as a normal directory unless they go digging around in the filesystem in preference to playing Minecraft. We have no idea if your nephew is someone that would do that.

    Or you could use a partition that uses a Linux filesystem, so you have standard permissions available to control access. Or you could have /home as a separate partition to reduce the size of your backup images. Or you could have just that user's Home directory as a separate partition. Or have a separate partition to be used just for that user's ~/.minecraft. Or use NFS to mount a filesystem from a different machine entirely. Lots of options.
