Reposting this issue (was MC-22315) because it was marked RESOLVED and considered a duplicate of MCL-22317. However, that issue (which had a slightly different error message anyways) was on Windows, and the only workaround provided was for Windows; my issue still persists exactly as described below, even after downloading the latest Linux launcher executable from https://launcher.mojang.com/download/Minecraft.tar.gz
The following error occurs when attempting to launch the Linux binary on a Linux machine with JRE 17 installed:
https://launchermeta.mojang.com/v1/products/launcher/6f083b80d5e6fabbc4236f81d0d8f8a350c665a9/linux.json MessageBox(Minecraft Launcher): Couldn't load launcher core from /home/<user>/.minecraft/launcher/liblauncher.so: LoadErrorNotPresent ----------------------------------------------------------------------- If this is your first time running Minecraft, please ensure you are connected to the internet so we can download updates.
Inspection of the bottom of the launcher log shows the following:
[Info: 2022-08-31 16:20:00.387073916: StartLibrary.cpp(61)] Starting /.../liblauncher.so [Error: 2022-08-31 16:20:00.387557323: LauncherPluginLinux.cpp(20)] Failed to load /home/<user>/.minecraft/launcher/liblauncher.so: libcups.so.2: cannot open shared object file: No such file or directory [Error: 2022-08-31 16:20:00.387572081: StartLibrary.cpp(90)] Couldn't load launcher core from /home/<user>/.minecraft/launcher/liblauncher.so: LoadErrorNotPresent
What is libcups.so.2, and why did the launcher not fetch it for me? My Internet connection is fine, and the launcher was able to download other files.
