I suspect a problem on my koha software.It shows that there are up dates which i,am supporsed to update.When i try to update or checking them i get this message " E: encountered a section with no package:header,E:problem with mergelist/var/lib/apt/list/security.ubutu.com_ubutu_dists_precise-security_main_binary-i386_packages,E:Thepackage lists or status file could not be parsed or open. When open the other it says that your installled packages have unmet dependencies.
This sounds like a support request rather than a bug report. Please consult your options for getting Koha support: http://koha-community.org/support/ ...particularly the Koha mailing list. Keep in mind that any requests for help should include the version of Koha you are using, your method of installation, and detailed description of what led to the error.
