1.16.201 is expecting a new libc version; Current docker build is experiencing disconnects with FileUnknown crashes #127

Based on the bug reports on servers crashing with 1.16.201 there may be a need to validate/update the linux libc library to match what the bedrock server is now expecting:

https://bugs.mojang.com/browse/MCPE-98133 https://bugs.mojang.com/browse/BDS-10666

I noticed that the latest versions of libc are 2.28 for debian buster but are 2.31 for ubuntu 20.04 so if the developers are building /testing on ubuntu 20.04 I could hypothetically explain the descrepency.

I took the dockerfile created here and change the FROM debian to FROM ubuntu and I'm getting build errors where I run out of space in /va/lib/docker/tmp (?!) so I may not be able to go that route but I will try running a game that is erroring on a new 20.04 VM I manually create to see if there's any change.

Even with 20.04 LTS with 2.31 libraries it still disconnected. Looks like more research is needed since it's failing on the newer libraries. I'll post the results to mojang for further actions.
