Get the latest version of mythtv from github:
    Make directory where to place it and go there
    run:
    git clone https://github.com/MythTV/mythtv.git mythtv
    
    If that does not work, first install git!
    
Next either install the pythonbindings from there into python3:
    go inside the downloaded data to:
        ...mythtv/mythtv/bindings/python
        (substitute ... with the location you downloaded it to)
    run:
        sudo python3 ./setup.py install
    install the following python modules if not jet there:
        https://pypi.org/project/mysqlclient/
        https://pypi.org/project/requests/
        https://pypi.org/project/requests-cache/
        https://pypi.org/project/python-dateutil/
        https://pypi.org/project/future
    by either 
        downloading the sourcefiles from above links, 
        unpacking them 
        and from the main directory within the unpacked files run:
        sudo python3 ./setup.py install
    or by finding the appropriate modules for your distribution.

or update the apropriate bindingfiles in your python2.7 binding directory
    on my system:
        /usr/lib64/python2.7/site-packages/MythTV
    on others possibly:
        /usr/local/lib/python2.7/dist-packages/MythTV
    or a variation of the above.
    
    Go to that directory
    first backup the tmdb3 directory in there by renaming it to tmdb3.bak:
        mv tmdb3 tmdb3.bak
    copy from the above downloaded git files the tmdb3 and tvmaze directory into this MythTV directory:
        sudo cp -rp ...mythtv/mythtv/bindings/python/tmdb3/tmdb3/ .
        sudo cp -rp ...mythtv/mythtv/bindings/python/tvmaze/ .
        (substitute ... with the location you downloaded mythtv into)
    install the following python modules if not jet there:
        https://pypi.org/project/requests/
        https://pypi.org/project/requests-cache/
        https://pypi.org/project/python-dateutil/
        https://pypi.org/project/future
    by either 
        downloading the sourcefiles from above links, 
        unpacking them 
        and from the main directory within the unpacked files run:
        sudo python2 ./setup.py install
    or by finding the appropriate modules for your distribution.
    
Go to the location of the graberfiles in:
    /usr/share/mythtv/metadata/Television/
        sudo cp -p ...mythtv/mythtv/programs/scripts/metadata/Television/tvmaze.py .
        sudo cp -p ...mythtv/mythtv/programs/scripts/metadata/Television/tmdb3tv.py .
        (substitute ... with the location you downloaded mythtv into)
    fix the bug at line 504 in tvmaze.py
    
        if not os.path.exists(cachedir):
-            os.makedirs(cachepath)
+            os.makedirs(cachedir)
        if sys.version_info[0] == 2:
            
    if you installed the python3 bindings, ensure the first line of both files points to python3:
        #!/usr/bin/env python3
        
    if you updated the python2 bindings,ensure the first line of both files points to python2:
        #!/usr/bin/env python2
        
if you updated the python2 bindings, you also have to update tmdb3.py in
    /usr/share/mythtv/metadata/Movie/
    go there and run:
        sudo cp -p ...mythtv/mythtv/programs/scripts/metadata/Movie/tmdb3.py .
        (substitute ... with the location you downloaded mythtv into)
    I have not tested this tmdb3.py version with python2!
        
Tests:
/usr/share/mythtv/metadata/Television/tvmaze.py -t
/usr/share/mythtv/metadata/Television/tmdb3tv.py -l en -a US -M Monk
/usr/share/mythtv/metadata/Television/tvmaze.py -l en -a US -M Monk
