I have upgraded to Plesk 10.0.1 no problem, however when I try to install the Small Business panel I get the following error: A dependency problem is found: required package psa-mail-pc-driver-10.0.0-cos5.build100091001.14.x86_64 conflicts with plesk-mail-qc-driver-10.9.0-cos5.build109101029.18.x86_64. No upgrade or obsolete solution was found for plesk-mail-qc-driver. Try to add plesk-mail-qc-driver to removable list.Problem occured during searching conflicts for package psa-mail-pc-driver-10.0.0-cos5.build100091001.14.x86_64 Error: Unable to proceed with the installation until the package plesk-mail-qc-driver-10.9.0-cos5.build109101029.18.x86_64 is removed from the system. Any help as to how to remove the offending driver without having to remove all the dependencies or bringing the whole system crashing down? Thanks.
