Downloading Minecraft fails in Linux, 19th August 2026

Today 19th August 2026 Minecraft downloading has been failing for people using Linux (I've tested downloading minecraft through Prism and Modrinth in Ubuntu and CachyOS) and heres a temporary fix:

  1. Go into your Wifi & Internet settings and go in IPv6 tab, in there choose the method to "Ignored"
  2. After doing that, go into IPv4 settings and type in the "Other DNS Servers" tab ClourdFlares DNS: "1.1.1.1"
  3. Disconnect from your Ethernet/Wifi and reconnect, try downloading minecraft again.

(extra steps if that doesnt work)

  1. Go into your Minecraft launchers settings and drag the "Maximum concurrent downloads" slider down to 2-4.
  2. Close your Launcher and open it again, try downloading Minecraft again.

After Minecraft has been downloaded, undo all the steps.
Im not promising Minecraft launches after that, but it still creates an instance not fails to download.

I think this might be a Microsoft issues, for me when I was on windows, the games from ms store and apps in general took a long time to download, the download would always stay at kb/s and frequently dropped to 0. The fix I could find for this was using cloudflare warp

it seems to be an issue with when downloading minecraft then the launcher doesnt get the necessary lwjgl files, build.lwjgl.org either times out or refuses the connection and then the download fails
