Hi,
thank you for your report and your help to make Ubuntu better.

From the log I've seen:
Configurando python3-cryptography (1.2.3-1ubuntu0.1) ...
dpkg-query: aviso: a interpretar o ficheiro '/var/lib/dpkg/status' perto da linha 13027 pacote 'libdbusmenu-gtk3-4:amd64':
 description faltando
Traceback (most recent call last):

    main()
  File "/usr/bin/py3compile", line 270, in main
    options.force, options.optimize, e_patterns)
  File "/usr/bin/py3compile", line 172, in compile
    interpreter.magic_number(version), mtime)
  File "/usr/share/python3/debpython/interpreter.py", line 233, in magic_number
    result = self._execute('import imp; print(imp.get_magic())', version)
  File "/usr/share/python3/debpython/interpreter.py", line 359, in _execute
    raise Exception('{} failed with status code {}'.format(command, output['returncode']))
Exception: python3.5 -c 'import imp; print(imp.get_magic())' failed with status code 139

Now while the second part is a python fail I wonder about the first which is complaining about being unable to read a proper state from "/var/lib/dpkg/status" - I wonder if this file is damaged on your system.
It is a critical part of the package management.

I can't guess what happened but you might try the suggestions made here to fix it up:
