When opening the launcher for the first time it opens normally and when I do it again it gives me the error:liblauncher.so errornotfound and in the log it says that I'm missing libc.so.6 (glibc)
I am using unity linix/ubuntu version 16 and I cant seem to be able to update/upgrade the libc6 library, the only efficient method I can do is save my worlds and version in a seperate folder the delete the .minecraft folder entirely.
