我目前正在为一个ARM设备（即Odroid C1+）设置自己的Ubuntu 16.04映像。因为我想定制运行良好的最小Ubuntu，所以我想安装“zookeeperd”包。
sudo apt-get install zookeeperd
执行此操作时，将出现以下错误：
sudo: unable to resolve host dualboot
Reading package lists... Done
Building dependency tree
Reading state information... Done
zookeeperd is already the newest version (3.4.8-1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
6 not fully installed or removed.
After this operation, 0 B of additional disk space will be used.
Do you want to continue? [Y/n]
E: Can not write log (Is /dev/pts mounted?) - posix_openpt (2: No such file or directory)

您是否也经历过同样的情况，或者知道如何解决错误？我发现类似的东西是：Error installing JDK: the keytool command requires a mounted proc fs (/proc). Windows subsystem for Linux
但我想澄清的是，我既没有在Windows 10的Linux子系统上工作，也没有在虚拟机上工作！
最佳答案
解决方案如下：https://superuser.com/questions/165116/mount-dev-proc-sys-in-a-chroot-environment
只需执行以下操作：
在主机中：
mount --bind /proc <chroot dir>/proc
以及另一种语法（在chroot环境中）：
mount -t proc none /proc
关于java - 在CHROOT环境中工作-尝试安装JDK时出错，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/44571510/
