Error during installation

[sakis2018]

I installed a fresh Ubuntu 14.04 - 64bit on my rootserver.
Then I made the following commands via Putty.

apt-get update && apt-get upgrade -y
apt-get dist-upgrade -y
apt-get autoremove -y

sudo echo "box.example.com" > /etc/hostname

sudo nano /etc/hosts
----
127.0.0.1 localhost.localdomain localhost
111.222.333.444 box.example.com box
....
----

reboot

apt-get install git

git clone https://github.com/mail-in-a-box/mailinabox
cd mailinabox
git checkout v0.27
sudo setup/start.sh

The following error message came up …

My domain hoster is namecheap.
There I have already created a glue-record.
At custom-dns I have entered the following:

ns1.box.example.com
ns2.box.example.com

what am I doing wrong? ask for help.

greetings

Have you really got spaces here

sudo echo “box.example.com”> / etc / hostname

It should be

sudo echo “box.example.com”> /etc/hostname

also

sudo nano / etc / hosts

should be

sudo nano /etc/hosts

No idea what affect this will have but its unlikely to work.

I had to translate the text, since my english is not that good, probably the spaces have been inserted by “copy & paste”. Anyway, of course I did it without the spaces.

Your server is having problem while resolving ppa.launchpad.net are you sure your outbound connections are not being blocked?

[murgero]

The script sets the server name also it looks like either DNS is broken on your box (it tells you this via the “could not resolve x” errors)

[sakis2018]

before I start the script, the server works perfectly. I can run apt-get update, etc. but as soon as I start the script and the upper error message comes I can not make an apt-get update anymore.

// update:

I have now found that the error is in the /etc/resolv.conf.
there is the following listed:

nameserver 127.0.0.1
search cw4.me

but if I enter the following under /etc/resolvconf/resolv.config.d/head

nameserver 8.8.4.4

and restart, then everything works.

How can I fix the error now?
