I am using Linux Mint 18 Cinnamon.Linux Mint has Software Center, just like Ubuntu Software Center in Ubuntu. After LinuxMint installation, I could run the software center in my system. But someday, may be after some operation like remove OpenJDK, install Oracle JDK,...the Software Center doesn't run anymore. When I click the Software Center icon or run from Terminal, the OS ask for super user password too, after entered the password, the round-spin (waiting) cursor appear for some seconds. After all, nothing happen. The Software Center doesn't run. Something I tried:Reinstall default JRE (OpenJRE)remove software-manager and reinstall software-managerThis is the output when I try to run sudo mintinstall$ sudo mintinstallVector smash protection is enabled.add_categories took 13.497 msbuild_matched_packages took 0.298 msadd_packages took 3828.769 msFirst run detected, initial set of reviews usedadd_reviews took 1022.018 msTraceback (most recent call last):  File /usr/lib/linuxmint/mintinstall/mintinstall.py, line 1920, in <module>    Application()  File /usr/lib/linuxmint/mintinstall/mintinstall.py, line 59, in wrapper    res = func(*arg)  File /usr/lib/linuxmint/mintinstall/mintinstall.py, line 617, in __init__    sans26 = ImageFont.truetype(self.FONT, 26)  File /usr/local/lib/python2.7/dist-packages/PIL/ImageFont.py, line 239, in truetype    return FreeTypeFont(font, size, index, encoding)  File /usr/local/lib/python2.7/dist-packages/PIL/ImageFont.py, line 128, in __init__    self.font = core.getfont(font, size, index, encoding)  File /usr/local/lib/python2.7/dist-packages/PIL/ImageFont.py, line 37, in __getattr__    raise ImportError(The _imagingft C module is not installed)ImportError: The _imagingft C module is not installed
