不久前，发现 MC 服务器居然不能输入指令关闭服务器，在启动过程中有报错。

查询到问题的原因是不久前升级的 Ubuntu 内核导致，附上原文：

All,

This is a message to let you know that Ubuntu has recently pushed what appears to be a bad kernel update to Ubuntu 18.04 users.

If you are using Ubuntu 18.04, please note that the following kernel appears to have issues handling console input:

4.15.0-44-generic #47-Ubuntu SMP Mon Jan 14 11:26:59 UTC 2019

Older (e.g. 4.15.0-43-generic #46-Ubuntu SMP Thu Dec 6 14:45:28 UTC 2018 ) kernels are not affected.

If you are using this kernel and have a message along the lines of “java.io.IOException: Resource temporarily unavailable”, this is the reason.

We are still investigating the exact cause / reason for this.

If you are affected by this issue there are a number of workarounds available (you only need to use one).

Spigot / BungeeCord: Add -Djline.terminal=jline.UnsupportedTerminal to your Java arguments

Spigot: Add –nojline to your Spigot arguments

Reboot your server and select 4.15.0-43, or any other non broken Linux kernel.

Install a non broken kernel: apt install linux-image-4.15.0-43-generic, remove the broken one: apt remove linux-image-4.15.0-44-generic, and reboot.

Please direct any queries to the 1.13.2 discussion thread, or general forums:

EDIT: Please see the below post for updates.
