unity error in a 16.04 LTS installation

[Stathis G. Arapostathis]

Hello Ralf,

 I checked the versions of the two packages you mentioned with the command:
sudo apt list --installed and it seems that I have the correct versions:

libharfbuzz-dev 1.0.1
libjarfbuzz-gobject0 1.0.1
libharfbuz-icu0 1.0.1
libharfbuzz0b 1.0.1

libfreetype6 2.6.1
libfreetype6-dev 2.6.1.0

I reinstalled these two packages you mentioned but nothing changed
unfortunately..

How could I check whether there are other inconsistencies and fix them? :)
Is there any solution on this issue or is it inevitable to reinstall ubuntu?

Thank you
Stathis
