I tried to install the theme but i'm getting this error and the installation fails when status is 'Working...'

Operation failed: E: Sub-process /usr/bin/dpkg returned an error code (1) ...

It's strange because i could install an other theme, TransparentTheme from MK99. iOS7 theme failed too, but without an error. But probably related.

Is this related to the theme or to Warehouse itself?
What to do?
