Issues building SDN base controller with unmet dependancies

RocTec — Tue, 18 Nov 2014 14:10:26 GMT

I am coming across a number of issues building a base controller.

Following the installation guide running on Ubuntu 12.04.5 LTS

first issue it get while install the keystone server section 2.1.2

2. Use the following commands to install the Keystone server on the local machine.
~$ sudo apt-get install python-software-properties
ubuntu-cloud-keyring

Error

python-software-properties : Depends: python-pycurl but it is not installable

~$ sudo add-apt-repository cloud-archive:icehouse

Command not found

I have tried installing but constantly come across issues. Has ubuntu 12 LTS support changed since the document was created?

I have tried to build it on 14.04 but come across simular issue with unmet dependancies but i know its not support on 14.

Any help or suggestion on a reliable method of installing the controller.

Hello,

for issue 1:

Looking at the command you posted the section "ubuntu-cloud-keyring" ends on a new line:

~$ sudo apt-get install python-software-properties

ubuntu-cloud-keyring

can you try to execute the command on a single line?:

~$ sudo apt-get install python-software-properties ubuntu-cloud-keyring

issue 2:

did you try to add the repository as shown in the manual (I'm going to use Icehouse in the example below):

~$ sudo add-apt-repository "deb http://ubuntu-cloud.archive.canonical.com/ubuntu precise-updates/icehouse main"

The controller should be installed on a Ubuntu server 12.04 (as from the manual you are following).

Please let me know whether the issue persists after modifying the apt-get and add-apt-repository commands.

Regards,

Antonio

Hi,

can you try to run:

anto@ubuntu:~$ sudo apt-get update

Then try to install needed packages?

If still facing issues please post the output of following commands:

anto@ubuntu:~$ dpkg -l

and

anto@ubuntu:~$ dpkg --get-selections

Also, Is this a fresh installation?

if not, was this server upgraded to 12.04 from an older version?

Is the server running on a VM? (if yes, considering that the error is related to the OS, it might be simpler to re-build it)

Did you install a GUI on the server?

Antonio

Is this an issue with my version of Ubuntu or will everybody be experianing these sorts of issues trying to install.

I have run into errors with the apt-get update

Posted this on the Ubuntu Fourm to try and resolve.

This was a freash install from the 12.04 LTS from http://releases.ubuntu.com/12.04/

I also ran the other 2 commands and attached the output

Hi,

I did never experience such issues in all installations I performed.

This looks to be an issue on your server.

Looking at the hash sum mismatch error it may be useful to run:

sudo rm -R /var/lib/apt/lists/*

and then again

sudo apt-get update

The files you uploaded does not seem to contain the output of the dpkg -l or dpkg --get-selections command.

Starting from scratch and following latest (and updated) installation guide may be a good idea though.

Regards,

Antonio

I have got the apt-get install update to work without failing although not entirely sure how

I ran

$ apt-cache search python-pycurl

bzr - easy to use distributed version control system

bzr-doc - easy to use distributed version control system (documentation)

python-bzrlib - distributed version control system - python library

$ apt-cache search python-bzrlib

python-bzrlib - distributed version control system - python library

python-bzrlib-dbg - distributed version control system - debug extension

python-bzrlib.tests - distributed version control system - testsuite

$ sudo apt-get install bzr-doc

The following NEW packages will be installed

bzr-doc

0 to upgrade, 1 to newly install, 0 to remove and 0 not to upgrade

But

apt-get install python-software-properties still failed

$ sudo rm /var/lib/apt/list/*

rm: cannot remove `/var/lib/apt/list/*': No such file or directory

$ sudo apt-get update

and then it worked.

I will build the rest of the controller and try and replicate the issue (I had rebuilt the server a number of times)

Thanks for the time and help.

Sorry, hadn't read the reply before posting,

Yes i think the

$ sudo rm /var/lib/apt/list/*

fixed the issue.

Thanks for the help.
