I am unable to create a logical partition using gparted.
My unallocated space is 27 GB.

How to send an installation report ?
i did run report-bug --configure.
Do you have a "mail transport agent" (MTA) like Exim, Postfix or SSMTP
configured on this computer to send mail to the Internet? [Y|n|q|?]? y
Default preferences file written. To reconfigure, re-run reportbug with
the "--
configure" option.

Please guide me.
