Working in CHROOT environment - Error when trying to install JDK

Question

I am currently setting up my own Ubuntu 16.04 image for an ARM device (namely an Odroid C1+). Since I want to customize the minimal Ubuntu which works fine, I want to install the package "zookeeperd".

sudo apt-get install zookeeperd

When doing so the following error appears:

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)

Do you experienced the same or have a clue how to resolve the error? Something similar I found was: Error installing JDK: the keytool command requires a mounted proc fs (/proc). Windows subsystem for Linux But I want to clarify that I am neither working on the Linux subsystem of Windows 10, nor in a Virtual Machine!

The solution is like this one: https://superuser.com/questions/165116/mount-dev-proc-sys-in-a-chroot-environment

Just do the following:

In host machine:

  mount --bind /proc <chroot dir>/proc 

and another syntax (in chroot environment):

  mount -t proc none /proc
