I have installed Unity in Ubuntu 16 . When I open for 1st time and sign in. I get this message "Service not available. Try again later"

For others with this issue: First, check if you have "libc6" installed (sudo apt install libc6). Secondly, run: sudo locate libresolv This will print a list to where the file is on your disk. For me, I had like three libresolv.so.2 but in different folders. Then, I ran the command written above and it worked. After signing in to Unity I can just start the program without having to use the above command again.

So for me: LD_PRELOAD=/lib/x86_64-linux-gnu/libresolv.so.2 /opt/Unity/Editor/Unity (Execute this command in terminal)
