network breaking in Ubuntu 14.04 VPS install?

[VJftw]

I have a Cloud VPS with OVH which I have installed Ubuntu Server 14.04 x64 using their online VPS manager.

I log in with root, and encounter the following when I try to install VestaCP

Code: Select all

Error: apt-get install failed

After this occurs, I tried running

Code: Select all

apt-get update

which failed as well as

Code: Select all

ping google.com

which returns unknown host

From this, it seems that running the Vesta installer somehow disables network connectivity on this VPS.

Any ideas on why this happening and how to solve this?

[inerd]

I am having that issue also :( My host is XtraHost :(

[VJftw]

I ended up modifying the installer to stop the bind9 dns service stopping.

http://vestacp.com/pub/vst-install-ubuntu.sh

try commenting out this line to look like this

Code: Select all

# Backup bind9
# service bind9 stop > /dev/null 2>&1

[imperio]

I am having that issue also :( My host is XtraHost :(

Your problem with OVH ?

[inerd]

Im not with ovh but with Xtrahost. It seems to happen around the hostname change :L

[imperio]

What error are you see?

[fluxxytux]

Has anyone found a fix for this ... ?
My Installation gets too ...
