[Bug 1750586] Re: package python-minimal 2.7.12-1~16.04 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

[Stephen Pape]

The post installation file /var/lib/dpkg/info/python-minimal.postinst
runs the following command:

python2.7 -m compileall /usr/share/python/ >/dev/null

Running the command manually (without the /dev/null redirect) produces
the following error for me:

Compiling /usr/share/python/rekall-forensic/lib/python2.7/site-packages/pexpect/async.py ...
  File "/usr/share/python/rekall-forensic/lib/python2.7/site-packages/pexpect/async.py", line 16
    transport, pw = yield from asyncio.get_event_loop()\
                             ^
SyntaxError: invalid syntax

I removed the /usr/share/python/rekall-forensic folder and was able to
"apt install -f". Likely a different package is causing you trouble, but
try running that command for more information.

Title:
  package python-minimal 2.7.12-1~16.04 failed to install/upgrade:
  subprocess installed post-installation script returned error exit
  status 1

Status in python-defaults package in Ubuntu:
  Confirmed

Bug description:
  There seems to be a dependency snarl:

  python-minimal is already the newest version (2.7.12-1~16.04).
  python-minimal set to manually installed.
  You might want to run 'apt-get -f install' to correct these:
  The following packages have unmet dependencies:
   python : PreDepends: python-minimal (= 2.7.11-1) but 2.7.12-1~16.04 is to be installed
   python-all : Depends: python (= 2.7.12-1~16.04) but 2.7.11-1 is to be installed
   python-all-dev : Depends: python (= 2.7.12-1~16.04) but 2.7.11-1 is to be installed
                    Depends: libpython-all-dev (= 2.7.12-1~16.04) but 2.7.11-1 is to be installed
   python-dev : Depends: python (= 2.7.12-1~16.04) but 2.7.11-1 is to be installed
                Depends: libpython-dev (= 2.7.12-1~16.04) but 2.7.11-1 is to be installed
  E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

  apt-get -f install tries to set up python-minimal (2.7.12-1~16.04) and
  returns 1.
