I have a python3.7 installed via brew on my Ubuntu 18.04. I can't make tkinter to work:

~ python3.7 -c "import tkinter"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/homes/0x90/.linuxbrew/opt/[email protected]/lib/python3.7/tkinter/__init__.py", line 36, in <module>
    import _tkinter # If this fails your Python may not be configured for Tk
ModuleNotFoundError: No module named '_tkinter'

This is the info of my tcl-tk and python3.7 environment:

~ brew info tcl-tk                                                                                                                                                                                 tcl-tk: stable 8.6.12

Note that I even tried to define the following environment variables but with or without them it fails to load tkinter as suggested on this thread:

setenv PATH /homes/0x90/.linuxbrew/Cellar/tcl-tk/8.6.12_1/bin:$PATH 
setenv PKG_CONFIG_PATH /homes/0x90/.linuxbrew/Cellar/tcl-tk/8.6.12_1/lib/pkgconfig:$PKG_CONFIG_PATH

I want to install libsystemd headers, but I can't.

output of apt-cache policy systemd:

# apt-cache policy systemd
systemd:
  Installed: 229-4ubuntu13
  Candidate: 229-4ubuntu13
  Version table:
 *** 229-4ubuntu13 100

     229-4ubuntu4 500
        500 http://us.archive.ubuntu.com/ubuntu xenial/main amd64 Packages

Here is the output of apt-cache policy libsystemd0:

# apt-cache policy libsystemd0
libsystemd0:
  Installed: 229-4ubuntu13
  Candidate: 229-4ubuntu13
  Version table:

Here is what happens when I do apt-get install libsystemd-dev:

# apt-get install libsystemd0 libsystemd-dev
