There is a a problem when you installating LibreOffice 4.3 from ppa.

/var/lib/dpkg/info/libreoffice-base.postrm: 31: /var/lib/dpkg/info/libreoffice-base.postrm: Syntax error: end of file unexpected (expecting "fi")
dpkg: error processing libreoffice-base (--remove):
 subprocess installed post-removal script returned error exit status 2
Errors were encountered while processing:
 libreoffice-base
E: Sub-process /usr/bin/dpkg returned an error code (1)

I used this solution :
http://askubuntu.com/questions/512162/libreoffice-base-not-configured-yet

/var/lib/dpkg/info/libreoffice-base.postrm
The missing line,
/usr/lib/libreoffice/share/basic/script.xlc
needs to be added to the end of the file's second if statement, just above the closing fi, like so:
--divert /usr/lib/libreoffice/share/basic/script.xlc.noaccess \
/usr/lib/libreoffice/share/basic/script.xlc
fi
