I had been using Calibre (downloaded from Ubuntu software center) on my Ubuntu 14.04 LTS. After adding some books to my library and a proper shutdown, the Calibre did not start. From Terminal too it did not get started hence I had to use ^C and it showed the following message. Is there any way to rectify this.
neo@neo-OEM:~$ calibre ^CUnable to open ~/.mtpz-data for reading, MTPZ disabled. neo@neo-OEM:~$ ^C
I tried removing and reinstalling but to no avail. However, the official website shows some incoherent (for me) way to download and install the latest version 0.2.3. If any one could help.
