Original GitHub issue: https://github.com/GameServerManagers/LinuxGSM/issues/1918

This problem is specific to a game, so it might not belong here. However, the LGSM documentation states it supports Ubuntu 12.04+, which appears impossible now as the required version of GLIBCXX needs Ubuntu 16.04

If this is the case, the documents need updating. If this isn't the case, then a solution to the missing file would be most appropriate.

Specifically, using a fully upgraded version of Ubuntu 14.04.5 LTS, trying to run a server results in a crash after the following part of initialisation:

This seems tied to an earlier error:

To anyone in a similar situation (using Ubuntu 14.04 wanting to host latest PZ server)... Docker is a fairly simple solution. There are automated builds out there that will run Ubuntu 16.04 (or later), install LGSM PZ server and boot it all up. Docker + LGSM work great together, making the tasks very simple.
