AWS Server - Ubuntu 14 - Issues launching wrapper - command not found

[ToxicStar-Kevin]

Gents,

Newbie question. Apologies learning AWS, Linux and Minecraft all at once. I have Minecraft working but now want to manage it via the GUI hence I'm trying your application. I want to remote manage the Minecraft server in AWS (not a fan of line commands) but failing at the the first hurdle. . I assume I'm doing something stupid as I follow the clear instructions on the wiki for the server wrapper but when I try and run it I get command not found. I assumed permissions and have tried variations and running under sudo without joy.

Help please.

Have you tried sudo chown USER * -R? In the SS you provided it seems to be the only thing you didn't do.

[ToxicStar-Kevin]

I had with Ubuntu substituted as I assumed the "USER" was the one i was assigned in. I can give it another go tomorrow if you think that is the root cause but I did repeat the instructions a few times since they seemed straight forward enough

This is really weird. You did change the NeMa file to an executable, so it should work.

Try running it with /bin/bash ./NeMa

[ToxicStar-Kevin]

Sorry there work and family getting in the way of my person hobbies.

Still no joy... at a lose as I can see the file and "less" it even though it is a binary. Permissions and ownership seems correct it just doesn't run.

The underlining PocketMine PE is working fine.

any suggestion on what to look at?

Really weird. I need to try it for myself. I see that you're using Ubuntu 14.04.4, is that correct? Is it the desktop or server version?

[LordMantil]

Did you get this resolved? I'm having the same issue on ubuntu

[TunkDesign]

@LordMantil I need more information to do the testing! What Ubuntu version are you using (desktop or server)?

[LordMantil]

@TunkDesign I'm running server 16.04.1

Hey, I thought I'd post my solution as I got it working.

You need to install the 32x libraries for Ubuntu if you are running 64x

sudo dpkg --add-architecture i386 sudo apt-get update sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 zlib1g:i386

Ubuntu 14.04.4 LTS (GNU/Linux 3.13.0-74-generic x86_64) Running PHP 7 and Java 8

Ok I will give that a go as I'm running the default 64x from AWS images.

[ToxicStar-Kevin]

The addition of 32x libraries worked... I was able to connect to the wrapper... so i assume going forward the app can be tweaked to also work with 64x only ?

[TunkDesign]

@LordMantil thank you for the solution! I will make sure to add that to the Wiki page and credit you. I'll see if I can include those libraries somehow in upcoming builds.
