Hi,
I installed first KIXCore, then when I installed KIX4OTRS I received this error:
ERROR: OTRS-otrs.Console.pl-Admin::Package::Install-95 Perl: 5.16.3 OS: linux

If I go to Package manager by the webpage KIX4OTRS appears like "correctly" installed.

Is this error affect something?

Thanks

Hi,
I installed a otrs-5.0.7-01.noarch.rpm version but when I tried to install KIX4OTRS I received errors due to framework and version don't match.

How can I uninstall otrs in order to install the lasted version?

I'm using centos so I´m connecting the server by putty
Thanks
