I also recall trying using the new (Electron?) launcher from the Minecraft website and having issues with it.
In fact, while writing this, I downloaded it and tried it out. When I tried executing "minecraft-launcher" from the terminal I get no output, last exit code 255. LDD finds no issues.

I found ~/.minecraft/launcher_log.txt, complains about missing libgconf-2.so.4.

[Error: 2020-03-19 19:02:41.009634851: LauncherPluginLinux.cpp(20)] Failed to load liblauncher.so: libgconf-2.so.4: cannot open shared object file: No such file or directory
Installed gnome-base/gconf (Woo, Python 2! Don't we have the shiny new dconf to replace gconf anyway?), starts up fine. Note that LDD doesn't mention libgconf, minecraft-launcher doesn't require it, liblauncher.so (and libcef.so) does.
Code: Select all
user@pc /tmp $ ldd minecraft-launcher/*

Try seeing if that's your issue or running ldd on all the libraries and executables (
hint-hint ldd minecraft-launcher/* | grep not\ found
hint-hint).
Wouldn't be first.
Also notice the distinct lack of activity from devs on these tickets and the fact that
discussing replacing dependency on gconf by dconf is not available to the public (look up the ticket number to at least see the name and description - thanks search engine metadata!
).
