Hello guys, i am facing a problem i have no solution for. After a dist-upgrade from squeeze to wheezy i wanted to reinstall plesk. During dist-upgrade i had to remove it. Finally i managed the auto installer to run through. But the qmail package will not be installed. I always get the following error. Code: Installing packages mv: cannot stat `/etc/drweb/drweb32.ini': No such file or directory Reading package lists... Building dependency tree... Reading state information... The following NEW packages will be installed: plesk-mail-qc-driver psa-drweb-configurator psa-qmail psa-qmail-rblsmtpd 0 upgraded, 4 newly installed, 0 to remove and 12 not upgraded.

It will not install. All databases and the complete /etc/ structure where backed up before dist-upgrade. For your information. Before managing to reinstall plesk, i installed qmail and courier-imap from debian sources. But they are already removed. Addtional information. The complete plesk installation failed a long time before it went through cause there where different libraries missing: Code: plesk-platform-runtime_1.0-892097.14062518_amd64.deb plesk-librdbmspp_2.0-735641.14062518_amd64.deb sw-mariadb-client_1.0.0-14033113_amd64.deb Also some libraries in the subfolder libboost-plesk-1.54.0 i had to link with ln -s to the parent folder cause it did not find it during installation. Any ideas how i get it qmail installed?
