Python update issue and broken packages

Two days ago I encountered an issue while trying to run the software updater.

Setting up python-minimal (2.7.12-1~16.04) ...
    Traceback (most recent call last):
      File "/usr/local/lib/python2.7/runpy.py", line 174, in _run_module_as_main
        "__main__", fname, loader, pkg_name)
      File "/usr/local/lib/python2.7/runpy.py", line 72, in _run_code
        exec code in run_globals
      File "/usr/local/lib/python2.7/compileall.py", line 16, in <module>
        import struct
      File "/usr/local/lib/python2.7/struct.py", line 1, in <module>
        from _struct import *
    ImportError: No module named _struct
    dpkg: error processing package python-minimal (--configure):
     subprocess installed post-installation script returned error exit status 1
    Errors were encountered while processing:
     python-minimal
    E: Sub-process /usr/bin/dpkg returned an error code (1)
    A package failed to install.  Trying to recover:
    dpkg: dependency problems prevent configuration of python-dev:
     python-dev depends on python (= 2.7.12-1~16.04); however:
      Version of python on system is 2.7.11-1.

    dpkg: error processing package python-dev (--configure):
     dependency problems - leaving unconfigured

Fix broken packages does not solve the issue, and I cant perform any other updates anymore, since I always get the above error.

I am using

and using the following repos

If I cannot update python to the latest version because python-dev that is needed for the update requires that python already is at that latest version, then how can I update python?
