Comment 18 for bug 1079972

Harry's fixed worked for me also.
And for the people out there (like me) who have trouble deciphering code.

1.Find the mythexport.postinst file
(for me it was at /var/lib/dpkg/info (unbuntu 14.10))

2. remove the line with the -- (as you will see the -- is not actually there)

3. add the line with the ++ in it's place (please leave the ++ off)

4. save and exit

5. apt-get install mythexport

6. done

(note: I had already manually created the .mythtv directory in the /var/www/ directory)

Hope this helps
