[ Update]:Newer versions of Xplico have solved this problem.

During the installation of Xplico, network traffic analyzer and sniffer (pcap compatible), may happen this error:

#dpkg -i xplico_0.5.2_i386.deb
After this operation, 0B of additional disk space will be used.
Setting up xplico (0.5.2) ...
chown: cannot access `/opt/xplico/xi': No such file or directory
dpkg: error processing xplico (--configure):
subprocess post-installation script returned error exit status 1
Errors were encountered while processing:
xplico
E: Sub-process /usr/bin/dpkg returned an error code (1)

If you create that missing directory by yourself and try to reinstall, another error will be prompted:

root@ubuntu:/home/adminuser/Desktop# apt-get install xplico
chmod: cannot access `/opt/xplico/xplico.db': No such file or directory

Till next package version, the current solution is uninstall and reinstall using this method:

1º) Uninstall:
# sudo dpkg -r xplico

2º) Manually delete the lines which mention port 9876
# nano etc/apache2/ports.conf

3º) Install the package with gdebi:
adminuser@ubuntu:~/Desktop$ sudo apt-get install gdebi

adminuser@ubuntu:~/Desktop$ sudo gdebi xplico_0.5.2_i386.deb

Xplico is a Network Forensic Analysis Tool (NFAT)
The goal of Xplico is extract from an internet traffic capture the applications data contained.
For example, from a pcap file Xplico extracts each email (POP, IMAP, and SMTP protocols), all HTTP contents, each VoIP call (SIP), FTP, TFTP, and so on. Xplico is not a network protocol analyzer.
