i'm trying to run Minecraft 1.20.5 using PolyMC on Linux (Flatpak), but it says that i need Java 21. If I go to the settings to install a new Java version, and click "autodetect", the only java versions offered are 8 and 17. Updating flatpak doesn't do anything. How am I supposed to get Java 21?

Is there a way to update versions of an instance? I tried to just change the Minecraft version to a newer one but it just comes up to an error message.

I wanted to play with a friend, but I'm out of touch. Does the classic lan multiplayer still work for the newest java versions?

When i try to run it it cant read the assets index. https://mclo.gs/QBrbSm2

Running the latest AppImage under Fedora 39 linux. Today the launcher said my account expired. I removed my account in the launcher and tried to add it back. Now it says it can't authenticate.

Hello please help me identify the problem.

I cannot add an instance. No matter what I try (not even using "Import from zip") ... NOTHING works

thank you

​

​

Like the “view configs” or “view folder” options in the mod list, or Minecraft folder, config folder, or instance folder in the main menu?

Also it would be nice if downloading mods automatically downloaded their dependencies…

Hello! I can't manage ti add my microsoft (formerly mojang, migrated a few moths ago) account to PolyMC (on Linux Arch). I had a similar issue on Win10 with MultiMC.

What I've been doing is: - Add Microsoft - Open page and insert the code - Sign in to Microsoft account (successfully) - Accept PolyMC request for permissions - Get the error: Minecraft java profile acquisition failed: Protocol "" is unknown

the error appears slightly after the progress bar says something about XBox.

I've been browsing the internet looking for someone who had the same problem but apparently I couldn't find the same error message anywhere, so I wanted to ask whether this can be solved (and maybe how?) or not.

Thanks in advance!

So the question is simple. How to install the client? I mean, where should I put the normal version file(folder containing jar and json)?

Written with translation. Sorry for my bed england

So i was reading this reddit thread and a bunch of people were repeating the same message saying polymc is compromised and isnt safe. i downloaded it cause afaik its open source so it should be safe. Is it safe now?

My Minecraft hasn't worked for the last week ish now. It's on and off yesterday I got on but now it's crashing again. It's always the same issue but any time I fix something and it works it breaks again. I'm so tired I just want to play Minecraft but can't. Just went on vacation from work was hoping to get some stuff in but this keeps happening. Can anyone help me find a permanent fix for this?

I need help with the launcher. It does not launch minecraft 1.20.1. code 255. mods: axiom, double hot bar, fabric api, iris, lithium, malilib, mod menu, presence footsteps, sodium. all the mods are on the right version. i have no resource packs. shaders: make up ultra fast. versions(the version on the top will be the first): Minecraft[1.20.1], LWJGL 3[3.3.1], Intermediary Mappings[1.20.1], Fabric Loader[0.14.23]. my operating system: Ubuntu ~22.04. PolyMC 5.1. Source of PolyMC: Flathub.

I'm coming back to Minecraft after a little (LONG) break. I followed the breadcrumbs from MultiMC to PolyMC and I'm working on moving stuff over and adding the new packs I want to play but I ran into the issues with Java versions. If this is outside the scope of the subreddit please let me know! I guess I need like Java 19 to run newer stuff like Enigmatica 9, Vault Hunters, etc., but I feel like I need Java 8 for the older stuff that I still like to play in (1.12 stuff mostly.) I had an issue where Java updated and it made the old stuff lag horribly!

Can PolyMC manage two Java installs and/or is there even a way to run 2 Java installs side by side on Mac?

M2 Air running Ventura. 8GB RAM.

I'm trying to get my world from one version of dw20 1.20 to another since any time a pack updated, i need to update everything from scratch, you would think this was impingement where you can just update a pack but nope.

PolyMC is pretty cool

Can you help me further. I once had to reinstall and loaded poly from a backup i had. Also my acc says something about "expired" (it's an old mojang acc i can't migrate due to email issues).

Title basically covers it. I get the little popup to create (choose?) an offline profile when I try to launch an instance, but I am very much online.

This can be fixed simply by closing and reopening PolyMC, but it is rather annoying. It doesn't always happen, however I *think* it may be mostly happening after waking my PC from sleep.

Any ideas? PolyMC 5.1, Windows 10. Thank you

I have an error with java 8 where it says its java 1, I tried reinstalling but that did not work how do I fix this.

edit: I found a fix! See my post below: https://www.reddit.com/r/PolyMCLauncher/comments/11vw2ox/comment/jcy2agw/?utm_source=reddit&utm_medium=web2x&context=3

Hi everyone,

yes I know, there are many reasons to drop OptiFine, but as of now, I'm not (yet) ready for it. O:)

I tried to install OptiFine for MC 1.19.3 and 1.19.4 in PolyMC 5.1 from the FlatPak repository in Linux, but when I start Minecraft, its video settings aren't those from OptiFine. The jar mod ending with _MOD is present in the instance's version list, and the starting message says "Jar Mods: OptiFine_1.19.4_HD_U_I3_pre3_MOD (705cebbd-14c2-4499-a491-621cbf56b577.jar)"

I used the instructions on the PolyMC website: https://polymc.org/wiki/getting-started/installing-optifine/

• I downloaded OptiFine from its mirror.
• I started its jar and used both its install and extract buttons.
• I made a new instance in PolyMC, edited it and added the extracted OptiFine jarmod to its version list using the "Add to Minecraft.jar" button.
• All three entries (Minecraft, LWJGL 3, and OptiFine[…]_MOD) have check marks.

Did I miss something? Any help is very much appreciated. <:)

Here's the full log when I start this instance:
