How to fix it and install the control panel?
And one more thing, during installation you need to enter "FQDN hostname", what is it? I just have ip, login, password from a dedicated server, and I don’t even know where this server is located and which provider, but I need to deploy the server.
And if you put the vesta control panel, will it be possible to work with TomCat? Because I already installed it.

Answer 1

firstly, you have an executor,
it must be completely demolished,
too, everything will be cleaned during installation,
no tomcat, you can’t
fcdn, this is your domain

Answer 2

Completely reinstall VPS on bare OS. Then update the packages and only then start the installation process.

Answer 3

The problem is solved like this:
First, remove
apt-get --purge -f remove roundcube-core
Then it swears at non-empty folders, clean them
rm -fr /etc/roundcube/ *
Then, if it rearranges the vesta, we make BECAP! all sites and databases, otherwise it can overwrite everything and put the message.
