[Sticky] Carbonio CE Related Scripts

@sharif I think that there's repetition in your script; try looking for ${!hostnames[@]} and you'll find two identical blocks:

• one dealing with "# Function to set the hostname"
• the other one dealing with "# Function to configure /etc/hosts"

I think to have discovered a little bug in the "Fan Made Script" (ce_installation_script_public_UB_v3.sh), when it comes to the "# Function to Change Admin User Password" routine. This is the original source code:

# Function to Change Admin User Password
change_admin_user_password() {
    echo "Changing admin user (zextras@$(hostname -d)) password..."
    read -s -p "Enter new admin password: " ADMIN_PWD
    echo # Move to a new line for clean output
    if su - zextras -c "carbonio prov sp zextras@$(hostname -d) $ADMIN_PWD"; then
        echo "Admin user password changed successfully."
        status[19]="Done"
    else
        echo "Failed to change admin user password."
        status[19]="Failed"
    fi
}

And this is my modification:

# Function to Change Admin User Password
change_admin_user_password() {
    echo "Changing admin user (zextras@$(hostname -f)) password..."
    read -s -p "Enter new admin password: " ADMIN_PWD
    echo # Move to a new line for clean output
    if su - zextras -c "carbonio prov sp zextras@$(hostname -f) $ADMIN_PWD"; then
        echo "Admin user password changed successfully."
        status[19]="Done"
    else
        echo "Failed to change admin user password."
        status[19]="Failed"
    fi
}

In the end it should be used hostname -f and not hostname -d for this command to actually work

su - zextras -c "carbonio prov sp zextras@fucine.email XXXXXX"

See, in fact, here:

root@mail:~# hostname -d
email

root@mail:~# hostname -f
fucine.email

So by using hostname -d I'd have gotten (which actually failed, for obvious reason):

su - zextras -c "carbonio prov sp zextras@email XXXXXX"

Whilst by using hostname -f I got (which worked, as we had to reference zextras@fucine.email):

su - zextras -c "carbonio prov sp zextras@fucine.email XXXXXX"

Quick guide:

Option Description Example
-i Displays the network address (IP) of the host | Example: hostname -i
-f Displays the Fully Qualified Domain Name (FQDN) of the host | Example: hostname -f
-s Displays the short hostname. This is the hostname up to the first ‘.’ | Example: hostname -s
-a Displays the alias name of the host | Example: hostname -a
-d Displays the DNS domain name | Example: hostname -d
-y Displays the NIS/YP domain name | Example: hostname -y
-n Displays the network node hostname | Example: hostname -n
-v Verbose output | Example: hostname -v
-h Displays help message and exit | Example: hostname -h
-V Displays version information and exit | Example: hostname -V

Furthermore, for anyone downloading the script from the link posted as comment to this YouTube video, it might be useful to convert it via:

dos2unix ce_installation_script_public_UB_v3.sh

If dos2unix is not already installed in your system then having it in place would be as easy as (for Debian GNU/Linux systems):

sudo apt install dos2unix

In the end it should be used hostname -f and not hostname -d for this command to actually work

Nope, in the end hostname -d is doing its job, but in case FQDN is referring to a 2nd level domain - which I think is the direct consequence of some step during script's execution (mine originally was "mail.fucine.email", but then it became "fucine.email") - then hostname -d would print just 1st level domain, and that should be avoided, of course.
Now I'm going to see at which step an originally defined 3rdlevel.domain.tld is rewritten in terms of domain.tld. Anyway this is what I have in place:

root@mail:~# cat /etc/hosts
127.0.0.1 localhost
78.46.195.130 fucine.email mail
root@mail:~# hostname -f
fucine.email
root@mail:~# hostname -d
email
root@mail:~# hostnamectl

I'm using your script on Ubuntu: 20.04LTS.It's amazing !
