Hi forum

I just installed QGIS 3.4 in Lubuntu 18.10 64 bit using repositories.

When I lunch the application I immediately get an error message

Couldn't load SIP module.
Python support will be disabled.


Traceback (most recent call last):
  File "", line 1, in
  File "/usr/lib/python3/dist-packages/qgis/__init__.py", line 80, in
    import qgis.gui
  File "/usr/lib/python3/dist-packages/qgis/gui/__init__.py", line 27, in
    from qgis._gui import *
RuntimeError: the sip module implements API v12.0 to v12.4 but the
qgis._gui module requires API v12.5

Python version:
3.6.7 (default, Oct 22 2018, 11:32:17)
[GCC 8.2.0]

QGIS version:
3.4.2-Madeira 'Madeira', 5645791

Python path:
['/usr/share/qgis/python',
'/home/giacomo/.local/share/QGIS/QGIS3/profiles/default/python',
'/home/giacomo/.local/share/QGIS/QGIS3/profiles/default/python/plugins',
'/usr/share/qgis/python/plugins', '/usr/lib/python36.zip',
'/usr/lib/python3.6', '/usr/lib/python3.6/lib-dynload',
'/usr/local/lib/python3.6/dist-packages', '/usr/lib/python3/dist-packages']


I've got QT version 5.1.1.


Could you help me? Thank you
