Unable to install Parallels Panel Web Hosting Component using autoinstaller on the Debian 7.2. The following error appears in
Unpacking psa-proftpd (from .../psa-proftpd_1.3.4c-debian7.0.build115130619.21_i386.deb) ...
dpkg: error processing /var/cache/apt/archives/psa-proftpd_1.3.4c-debian7.0.build115130619.21_i386.deb (--unpack):
trying to overwrite '/etc/pam.d/proftpd', which is also in package proftpd-basic 1.3.4a-5+deb7u1
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)
It means that the previously installed proftpd server conflicted with psa-proftpd_1.3.4c-debian7.0.build115130619.21_i386.deb package.
It is possible that you have installed it manually before Plesk was installed on the server.
dpkg --list | grep proftpd
Remove the existing proftpd-basic package:
dpkg --remove proftpd-basic
Install the Panel Web Hosting Component again using autoinstaller.
