Can I Install Termux on Linux?

We can install a Linux sub-system like CentOS or Ubuntu on Termux, but is it possible to have a Termux-like sub-system on Linux? In Termux the installations of some packages are much easier with *pkg install*. And Termux provides many resources that cannot be obtained directly using one line of code on pure Linux. I came up with this idea when I was learning Termux on my phone and found the limited screen and soft keyboard really troublesome. (don't tell me that I need an Android emulator or virtual machine)
