Tryingto upgrade Java to the latest version of the Minecraft server (v1.18), I had a bit of a drama because the server was initially running Ubuntu 19.x, so I've converted to 20.04 after finding the place that allows me to update all the packages and do the upgrade.
The version 1.18 here is extremely laggy, I can play any other version without any problems, in 1.17 I have no problem at all, but in 1.18, I can barely get 30 FPS, while in 1.17 I can get 120 FPS, the game has small 0 FPS freezes all the time, none of that in 1.17, to create a world sometimes it's 5 minutes, in 1.17 it's 30 seconds, and my PC even overheats in this version, why does all this happen? Is this version really very poorly optimized?
The 1.18 update in particular may be expected to be more computationally intensive (thus lagging more on a given machine) simply becasue the number of loaded blocks was increased by 1.5. [As noted exlsewhere, the factor experienced may be worse as much of the increase was the addition of the negative Y levels which are not simply air blocks.]
The advice you got in -edition-support/3056801-dropping-for-no-reason-to-0-fps may seem extreme, but would cover several posibilities beyond that the game has outstripped the abilities of your computer.
And I didn't want to remember this topic, when I think about reinstalling and losing EVERYTHING, I think about the biggest nightmare of my life, and if all that will be said here is "reinstall and that's it" then there's no reason for me to say here.
If this is what is happening, I would expect the time before the game crashes to rise if you push the optimization (render distance of 4, no particals, fast grahpics, etc.). I'm not suggestiing you try to play with those settings, merely test them to see if the performance changes in ways that might indicate the nature of the problem.
Install profile -
Once in the server, on the left hand menu click on the profiles section and download 1.18.1 from the Mojang repo.
You can change the repository and install Paper, Spigot, Waterfall and many others if that is your cup of tea.
Create the server -
On the left hand menu, click create a server, give it a name and save it. You can change any of the other options as desired. I do recommend changing the port from the default 25565 to something else. This will allow other MC servers to run on your network with out incident. (Ask me how I know)
Error: mineos had a failure Exception: RuntimeError Message: Last 10 lines: fatal: remote error: The unauthenticated git protocol on port 9418 is no longer supported. Please see LINK REMOVED for more information. Partial plugin destroyed
If you plan on just hosting the server locally and letting your friends come to your house to log in then it is pretty striaght forward. Once the server is setup, you can all log in the same way - by adding a multiplayer server from within the minecraft game menu.
I have just followed the above instructions and setup a working MC server in a ubuntu server VM. To connect to the server you add a new server in the multiplayer section of minecraft using your VMs ip address followed by :25565 (example -
192.168.1.0:25565)
The TrueNAS server I originally had it setup on is still running but just as a NAS. I have moved away from plugins in TreuNAS core (besides PLEX, which still works fine) as they seem to be getting forgotten about with development. It seems that TrueNAS scale is the way to go moving forward in regards to plugins and VMs. But CORE is a a very solid option for NAS only needs.
I have moved my minecraft server to a proxmox cluster running under ubuntu server using a simular process descibed above to set it all up. I have to say, having had the chance to play around with proxmox for a while now, it really is a great choice for VMs. If you can get a backup server running as well (can be run as a VM on truenas scale) you have a really SWEET home lab solution. I have been using a bunch of HP elitedesk minis as a proxmox 2 node cluster with a 3rd machine acting as a backup server, I also have home assistant with a coral TPU USB stick as my home assistant server. What a world we live in where I can get thses machines for $150AUD each. =D
The official minecraft server works and I am able to login as well as my kid locally within the LAN but it seems to poop out after a while and refuse to load/render chunks. I did set the chunk distance to 36 (from the default 10 or so chunks).
So I've been watching some of the Hermitcraft "Season 8" videos on YouTube, and one of the "problems" they've come across is the change in ore distribution - particularly diamonds. Basically, they've found that diamonds are more rare than they used to be.
The recently released "Caves and Cliffs - Part 1" update is version 1.17. This is what the hermits are playing in season 8. Here is the official information from Mojang about splitting the update in two parts: -us/article/a-caves---cliffs-announcement
The diamond ore distribution is not changed in 1.17, it is still a uniform distribution in levels 1-15. However, there seem to be some incidental changes because of world generation changes of other elements around these levels. Here is a video that shows a comparison: .
The confusion is due to the upcoming (fall 2021) "Caves and Cliffs - Part 2" update, which will be version 1.18. There, the distribution of all ores will change significantly. Mojang have shown what exactly they intend to change, that is why on the internet there is a lot of information about 1.18 even though it is not released yet. Of course, things can still change significantly before the final release of 1.18.
Mojang may have notably snapped off the caves and cliffs bits from the first half of their Caves & Cliffs update to Minecraft, but it looks like the second half will be worth the wait. Mojang released an experimental snapshot for 1.18 yesterday and folks have started finding some absolutely wild worlds created by the new terrain generation. If you've not had time to take it for a spin for yourself, here are quite a few screenshots and videos of some things that have been spotted so far.
I loaded up the experimental snapshot myself today and if all these major world gen changes are a bit unsettling to you, don't worry. I didn't immediately find myself chucked into some floating island nullverse world. It's still definitely Minecraft, albeit with mountain-ier mountains and cave-ier caves.
Some other folks have put in the time to look for and share their seeds for neat 1.18 finds though. Here's one particular world, shared on Reddit, that really shows off some of the wild multi-level cave generation going on in 1.18. You can spot a flythrough video by the poster there in that link with the lighting all turned up to better see all the blocks. Up top is my view. I had to turn up my render distance to 24 chunks to capture the back of the cave from the surface. Here's a bit more of it, with some lush caves and tons of waterfalls:
Do remember, of course, that this version of 1.18 is far from final. In their announcement post from yesterday, Mojang caution that this snapshot could still be quite different from the full release of 1.18. "Some features may be significantly changed or even removed if needed to improve performance," they say.
There's obviously a lot going on here. New mountain biomes are relatively self-explanatory, as are the local water and lava levels which Mojang have shown us before. What is the difference between a spaghetti cave and noodle cave though? I don't know yet, but I'm eager to find out.
That's all the most photogenic stuff, of course. Given the experimental nature, you're bound to wander across some more nonsensical new terrain if you choose to try out the snapshot yourself. Directions on how to do that are also in Mojang's announcement.
As for the final version, Mojang say that traditional snapshots for 1.18 are likely to begin around September, with the final release still expected near the end of this year.

I've always really enjoyed Minecraft's villages and the interesting ways that they sometimes generate. So before I go, here's one I found while flying about earlier. It's a desert village that appears to have taken a beach vacation.
The release of Fabric for Minecraft 1.17 was almost 6 months ago. Since then, we have updated to all 7 experimental snapshots, 8 snapshots, 8 pre-releases, 4 release candidates, and the final release version of Minecraft 1.18.
Hundreds of mods have already been updated to support 1.18 and we expect there will be many new and updated mods being released soon. We kindly ask that you be patient as mod developers update their mods.
To set up a development environment you will need to use Java 17, Loom 0.10, and Gradle 7.3 or higher. If you need some help getting set up, please go to #mod-dev-gradle-ides on the official Discord server.
Hello MineOS/Minecraft friends. I thought I would make this post to hopefully help out some folks that will be updating in the next few days. I run MineOS in a docker in unRAID. In order to get my servers running on the fancy new update, 1.18, I had to update the java version in my docker. This should work for stand alone Linux OS/VM/etc (not for windows). You might have to tweak some steps a little based on your setup.
Thank you so much for this information. I am completely linux illiterate but was able to use your post and another about upgrading to JDK 16 to do this from the command line using wget (first time ever) for those in a similar situation, here is how to do it from the CLI:
Minecraft 1.18 has arrived today, bringing with it giant changes to the way that worlds are generated. Caves & Cliffs part 2 has made Minecraft's terrain dramatic. Mountains now stretch up into towering Frozen Peaks biomes the likes of which earlier versions never would have created. Massive caves are open along the surface, earthen maws ready to swallow you down to deepslate depths without warning. Entire mountains are hollow, filled with new Lush Cave interiors. Each new world I visit has landscapes that are dauntingly large, excessively strange, and ultimately fascinating in the way Minecraft was when I first played it.
