nethserver-squidclamav (which calls ecap-clamav and clamav-data) conflicts with nethserver-antivirus which gets clamav-data-empty as dependency.
since ecap-clamav is built with clamav-devel, probably we cannot do something here, but nethserver-antivirus has a ‘Requires: clamav-data-empty’, so if we ‘obsolete’ it, we could add ‘Requires: clamav-data’.
I think @davidep is right.
clamav-data and clamav-data-empty should conflict because they offer the same files.
Packages should require “data(clamav)”, the sysadmin choose what package suits his needs. NethServer chose clamav-data-empty.
