Re-install Roundcuvbe don´t work

[LarsM33]

Hello,

i have installed Plesk 11.5.0 on my Ubuntu 12.04.4 LTS Root Server.

I have installed Roundcube with the installer and it works fine. i have changed the Roundcube Logo and the Text to my own and it works.
Then i installed an Carddav Plugin . I downloaded the Plugin File unzip these and copy it to /usr/share/psa-roundcube/plugins. After that i edited the main.inc.php at this point nothing works.
Blank Page when i go the webmailer.

i removed the files and the edits in the main.inc.php but it won´t work anymore.

At this Time i uninstalled Roundcube from Plesk with the Autoinstaller frontend but i get an Error that says the Directory is not empty (/usr/share/psa-roundcube)
I removed the files with SSH Connection.

When i re-install Roundcube it seems there are problems with Dropbear and the SSH Keys and the Installation stops.

That is the Error from the Autoinstaller.log

Setting up dropbear (2011.54-1ubuntu0.12.04.2) ...
Converting existing OpenSSH RSA host key to Dropbear format.
Error: Unexpected end of file
Error reading key from '/etc/ssh/ssh_host_rsa_key'

Errors were encountered while processing:
 dropbear
E: Sub-process /usr/bin/dpkg returned an error code (1)

What can i do? The Files are back at the Roundcube Directory.
