[SOLVED] Upgraded to LL2.6 - Lite Control Center won't open...

[m654321]

I am having problems again, with opening the Linux Control Center in LL2.6

The output from the terminal is as follows:

mike@LL-G750JS:~$ lite-controlcenter
Traceback (most recent call last):
  File "<frozen importlib._bootstrap>", line 2158, in _find_spec
AttributeError: 'DynamicImporter' object has no attribute 'find_spec'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/share/litecc/litecenter.py", line 13, in <module>
    from gi.repository import WebKit as webkit
  File "/usr/lib/python3/dist-packages/gi/importer.py", line 53, in find_module
    'introspection typelib not found' % namespace)
ImportError: cannot import name WebKit, introspection typelib not found

When this happened before (see previous posts on this thread), it was fixed by installing girl.2-webkit-3.0, but in this instance this didn't seem to work - here is the output from the terminal...

mike@LL-G750JS:~$ sudo apt-get install girl.2-webkit-3.0
[sudo] password for mike:
Reading package lists... Done

E: Unable to locate package girl.2-webkit-3.0
E: Couldn't find any package by regex 'girl.2-webkit-3.0'
mike@LL-G750JS:~$

Any help is much appreciated.
Many thanks & Merry Christmas
Mike
