Updating to latest errors with could not determine the IP or IPv6 address of the network interface

[arjitc]

I've been trying to update to the latest version but I get the following error,

Version: mailinabox.version returns "13" under /home/user-data

After running the command,

curl -s https://mailinabox.email/setup.sh | sudo bash

I've masked my IP with "AAA.BBB.C.DD". The server has network access and the IP returned back when checking with checkip.amazonaws.com is the same as "AAA.BBB.C.DD"

The following error is seen after the Hostname step,

I could not determine the IP or IPv6 address of the network inteface
for connecting to the Internet. Setup must stop.

What happens if you run:

ip route get 8.8.8.8

What happens if you run:

ip route get 8.8.8.8

The output is blank/no output.

but, I was able to get around this issue by editing the file /root/mailinabox/setup/questions.sh

changing,

if [ -z "${PRIVATE_IP:-}" ]; then
        PRIVATE_IP=$(get_default_privateip 4)
fi

to

if [ -z "${PRIVATE_IP:-}" ]; then
        PRIVATE_IP="127.0.0.1"
fi

and then the update worked fine. The virtual machine/system has a slightly different network setup often seen with hosts like OVH.

The output is blank/no output.

Alright. That's the reason why we get an error there, I guess.

It's cool that it works for you now. I hope that this problem won't occur to often - otherwise we need to think about a patch or another way to determine the address.

@arjitc You'll need to find out what has taken over the "ip" command. Either by alias or another package (run \ip route get 8.8.8.8 to see if it is an alias). Or you may not have the iproute2 package. installed.

This is what my box looks like

root@m:~# alias ip
-bash: alias: ip: not found
root@m:~/mailinabox# which ip
/sbin/ip
root@m:~/mailinabox# dpkg -S /sbin/ip
iproute2: /sbin/ip
root@m:~/mailinabox# dpkg -l | grep iproute2
ii  iproute2                            4.15.0-2ubuntu1.2                           amd64        networking and traffic control tools

@jvolkenant I have pretty much the same output here for the commands :)

root@mail:~# alias ip
-bash: alias: ip: not found
root@mail:~# which ip
/sbin/ip
root@mail:~# dpkg -S /sbin/ip
iproute2: /sbin/ip
root@mail:~# dpkg -l | grep iproute2
ii  iproute2                               4.15.0-2ubuntu1.2                               amd64        networking and traffic control tools
