I'm not very linux savvy so please be kind

I successfully upgraded (for the second time) following your very easy instructions here.
During the update it suggested that I uninstall Horde (because of something to do with the domxml uninstall). Thinking that this was merely part of the process I said yes and went ahead.
Although not absolutely necessary I would like to get Horde back on my shiny new updated system.
I tried through the Plesk Updater to re-install Horde yet no joy.
The log gave me
Code: Select all
Preparing for packages installation...

Looking forward to any and all responses.
