re-ran the glibc instructions to no avail.

I make a marine look smart :D so small words and big writing with crayons would be helpful. :D

most probably you are using an older version of java, see this post:- https://forums.unraid.net/topic/84880-support-binhex-minecraftserver/?do=findComment&comment=1003252

 

and if the variable JAVA_VERSION isnt shown in your template then check here:- https://forums.unraid.net/topic/84880-support-binhex-minecraftserver/?do=findComment&comment=1003689

Thankie!

The crayons were tasty, and I was missing the JAVA_VERSION thingie.  Probably because I never touch these things unless the kid says "DAAAAAAAD!!! THE WORLD IS BROKEN! FIX IT PLEASE!!!" :D

I now get incompatible client, please use 1.17, but I am using the 1.17.1 client. Is there a way to force the server to use 1.17.1 instead of defaulting to the older 1.17.0 version? Restarting the container and it still picks up the old version.

I have set JAVA_VERSION to 16 correctly, but the entrypoint script is unable to find a jvm there:

 

2021-07-06 18:26:07.521942 [info] JAVA_VERSION defined as '16'
'/usr/lib/jvm/java-16-openjdk' is not a valid Java environment path

 

So it's picking up JAVA_VERSION but thats not helping. I tried setting a JAVA_HOME but that didn't work either.

Having an odd issue with, I"m assuming, the backup script. Noticed this a couple weeks ago with 1.17 and still with the latest 1.17.1. It looks like the script is leaving the server in the save-off state sometimes. So changes made are not saved if the server is shutdown. 

 

Here's some of my console today. The last two save-on commands were typed by me. I have the server set to backup every hour due to this issue.

thanks for this, i see why it tripped up at one point but im confused as to why this happened:-

 

save-on
[20:08:12] [Server thread/INFO]: Automatic saving is now enabled
save-on                                   
[20:08:23] [Server thread/INFO]: Saving is already turned on

 

it clearly printed to the console that automatic saving is now enabled but for some reason my backup script fails to see this in the log and thus issues another save-on, very odd!.

 

in any case i have added a little bit more robustness to it so it now looks for the message 'Saving is already turned on' and 'Saving is already turned off' as well as the normal messages, please pull down latest image and let me know how you get on.

Hi, I'm on the 6.9.2 version of Unraid, I have had the minecraft serverworking previously but it stopped after I updated the docker today.  I can't get the webui to open either, it just says it can't connect.

 

The last line in the docker log is '/usr/lib/jvm/java-16-openjdk' is not a valid Java environment path.   I force updated the container to see if it would fix it, but still getting this.   Any ideas?

My server broke too, and I am getting the same message as you. I downgraded to the previous release to get it running again. I guess they broke something in this release.

 

If you wanna try, you can add :1.17.1-01 so it will be like this binhex/arch-minecraftserver:1.17.1-01 in the "repository" line to make it downgrade to the previous release.

Sorry for the confusion. Those last two save-on commands were manually typed by me into the console to confirm that automatic saving had been turned off by the script at 15:03:25. 

 

Thanks much for the updated container! I'll report back if the issue re-occurs.

Still seeing this issue unfortunately. Backups are being taken every 6 hours. Last mention of any saving activity in the console was at 06:37 where the server was left in a save-off state. A backup (folders created with world files) was taken at 12:37 & 18:37 but no activity was shown in console. Around 19:00 (after I grabbed the attached logs) I manually typed a save-on which gave me the "Automatic saving is now enabled" message.

As a heads up, when I installed the container with the supplied template, it would not launch until I updated the Java version to 16. I was getting an error in the web GUI until I made that change. Not sure if you want to change the default value.

I know you didnt want people using custom variations for this very reason but my kids love their optifine world and I had to use it to get it to work on unraid.  It appears that this update has killed the MAIN_EXECUTABLE variable, or i am not doing something right. I can get it to start but only as 17.1 which wont work.  Is there another way to get their custom 1.16.5 optfine to work now?

what is JAVA_VERSION set to?, it should be 8 for minecraft version 1.16.x or earlier

It is set to 8 and the custom jar is selected but it still runs 1.17.1
