How do I install Open vSwitch on raring? I can't find any official Ubuntu docs on this anywhere.
DevStack seems to do this:
kernel_version=`cat /proc/version | cut -d " " -f3`
apt-get install make fakeroot dkms openvswitch-switch openvswitch-datapath-dkms linux-headers-$kernel_version
On the other hand, this blog does this:
apt-get install openvswitch-datapath-source openvswitch-common openvswitch-switch
I did an Ubuntu server install using preseed. When I log in, it doesn't tell me how many packages (including security packages) require an upgrade, and when a restart is required. How do I configure it to show me these things on login?
I'm trying to install Ubuntu server from ISO, on a system that doesn't have networking connectivity to the Internet, but I'm not able to get past a certain point.
Initially, the process proceeds normally, it seems to partition things correctly and installs the base system.
However, when I get to the "Configure the package manager" stage in the "Ubuntu installer main menu", and I hit "enter", I see a dialog that says "Configuring apt" with a progress bar, and then it goes right back to the "Ubuntu installer menu".
The same thing happens no matter what other option I select (e.g., Install the GRUB boot loader on a hard disk, Finish the installation, Abort the installation): a dialog that says "Configuring apt" with a progress bar appears, and then it kicks back to the installer menu.
I'm at a loss to how to troubleshoot this, since I don't see any error message during this process.
I've tried both Ubuntu Server 12.04 and Ubuntu Server 12.10, same result.
I attempted to set my local timezone to America/New_York by doing (as root):
# cp /usr/share/zoneinfo/America/New_York /etc/localtime
# echo "America/New_York" > /etc/timezone
# dpkg-reconfigure --frontend noninteractive tzdata
The "date" program reports the right time zone:
$ date
Thu Feb 14 16:51:28 EST 2013
However, /var/log/kern.log is still reporting times in UTC, e.g.:
Feb 14 21:38:28 newyork kernel: [39716989.760755] xvdf: unknown partition table
Do I need to reboot to fix this? or is there something else I need to change?
On 12.04, when I do apt-get install on postgresql (which is already installed), it returns an error that mentions rabbitmq-server. What are the circumstances that could cause this type of failure?

I'd like to have a unity desktop accessible via VNC on a precise server machine I have running. I installed the ubuntu-desktop package. I'm launching a VNC session with the following in my ~/.vnc/xstartup file:
#!/bin/sh
xrdb $HOME/.Xresources
xsetroot -solid grey
export XKL_XMODMAP_DISABLE=1
gnome-session --session=ubuntu-2d
What could the issue be here? The content of my /usr/share/gnome-session/sessions/ubuntu-2d.session file (this is what 12.04 puts there by default) is:
[GNOME Session]
Name=Ubuntu 2D
RequiredComponents=gnome-settings-daemon;
RequiredProviders=windowmanager;panel;shell;
DefaultProvider-windowmanager=metacity
DefaultProvider-panel=unity-2d-panel
DefaultProvider-shell=unity-2d-shell
DesktopName=Unity
I don't know anything about unity-2d, but I guessed that the default session was not configured to use the launcher. I tried making the following modifications:
[GNOME Session]
Name=Ubuntu 2D
RequiredComponents=gnome-settings-daemon;
RequiredProviders=windowmanager;panel;shell;launcher;
DefaultProvider-windowmanager=metacity
DefaultProvider-panel=unity-2d-panel
DefaultProvider-shell=unity-2d-shell
DefaultProvider-launcher=unity-2d-launcher
DesktopName=Unity
But I got the following warning in my VNC log file:
gnome-session[10354]: WARNING: Unable to find default provider 'qr' of required provider 'launcher'
And the VNC session wouldn't even start with that configuration.
I'd like to use virt-install to create a VM with a specific MAC address. The virt-install man page has this restriction about specifying a MAC address:
For Xen virtual machines it is required that the first 3 pairs in the MAC address be the sequence '00:16:3e', while for QEMU or KVM virtual machines it must be '52:54:00'.
What's the purpose of this restriction?
Note that when I create instances with OpenStack (which is using kvm via libvirt), the instances are assigned MAC addresses start with fa:16:3e, and everything seems to work fine.
Is there an equivalent to doing aptitude safe-upgrade using apt-get?
I've launched an Ubuntu 11.10 instance (oneiric-server-cloudimg-amd64-disk1.img downloaded from here) inside of KVM, with VNC enabled. I can connect to the instance using VNC, and I see a login prompt.
I'd like to be able to use this VNC connection to show an X session instead of a text prompt. What do I need to install/configure so that this VNC session exposed through KVM shows an X11 session?
(Note that I can successfully switch between tty[1-6] by doing Ctl-Alt-F#).
I'd like to make some changes to my networking configuration by editing my /etc/network/interfaces file. What's the cleanest way to make changes to this file and have them take effect, without having to reboot? Typically, I've been doing:
service networking restartBut I have the impression that this isn't the "right" way to make these kinds of changes.
I'd like to use the adduser command to add a user (with disabled password) via a shell script.
By default, adduser prompts you for various values (e.g., Full Name). Is there any way to submit these values via command line? Or will I need to useradd instead?
I'm creating customized binary versions of OpenStack nova packages (lp:nova) using their packaging scripts (lp:~openstack-ubuntu-packagers/ubuntu/natty/nova/ubuntu).
I create binaries by doing:
dpkg-buildpackage -b -rfakeroot -tc -uc -D
This creates a set of packages (python-nova, nova-common, nova-compute, ...).
In our customized version of the code (lp:~usc-isi/nova/hpc-trunk), we recently merged in some changes from another branch, and there's now a new file in our repository that wasn't in upstream: nova/virt/cpuinfo.xml.template.
This file isn't getting added to any of the packages, where it should be added to python-nova.
Why wouldn't dpkg-buildpackage be including this file? A more basic question: how does dpkg-buildpackage determine which files go in which packages? Is it related at all to the debian/watch file? This contains some URLs that are pointing to the upstream project.

When I install rabbitmq-server package on Lucid, I always get a warning about upgrading from a previous version (even though no previous version is installed), and then I have to hit enter to dismiss the dialog. Is there any way to disable this prompt so I can do the install unattended?
I've tried to set up a trivial repository with binary .debs for internal use, but apt-get doesn't see the packages. I've done the following:
On the web server:
http://www.example.com/packagesGenerated a Packages.gz file in the same directory by doing:
dpkg-scansources . /dev/null | gzip -9c > Packages.gz
On the client machine:
Added the following line to my /etc/apt/sources.list file:
deb http://www.example.com/packages /
Ran: sudo apt-get update
The output related to my trivial repository looked like this:
Ign http://www.example.com Release.gpg
Ign http://www.example.com/packages/ Translation-en_US
Ign http://www.example.com Release
Ign http://www.example.com Packages
Ign http://www.example.com Packages
Hit http://www.example.com Packages
But I can't install the package by name. For example, there's a package called "python-nova" which corresponds to package python-nova_2011.3-custom~bzr680-0ubuntu1_all.deb
I've tried to do: apt-get install python-nova, but I get the following error:
$ sudo apt-get install python-nova

Many packages built for Ubuntu seem to have a "-0ubuntu1" suffix (or, more generally, -XubuntuY). For example, the version string for a bleeeding-edge package from the nova project looks like:
2011.2~bzr663-0ubuntu1
I understand that 2011.2 is a major version, and bzr663 refers to revision 663 in the bzr repository, but what is the meaning associated with 0ubuntu1?
When I generate and upload source packages to my PPA, what's the best way to pass DEB_BUILD_OPTIONS that Launchpad will use when building binary versions of the package?
In particular, I want to pass in the "nodocs" option so that the documentation isn't built.
I'm trying to upload packages to my PPA for the first time.
I want to use the PPA for customized versions of the OpenStack Compute (nova) project, so I tried to do a test by uploading packages corresponding to the bexar release of this project (lp:nova/bexar), with a new version number and changelog entry. I signed the source packages using my OpenGPG key, which has been uploaded to the ubuntu keyserver:
$ dch -v 2011.1-0ubuntu2-isi1 -D lucid "ISI bexar build #1"
$ dpkg-buildpackage -s -rfakeroot -tc -D -k4C8A14AB
When I tried to upload the files to the repository, it seemed to work (real email obscured):

However, the packages aren't listed on my PPA page. If I try to upload again, I get the error:

Nothing more to do for nova_2011.2~bzr663-1isi1_source.changes
Am I supposed to do something next? How do I track down what wrong? As of this writing, it's been a day and a half since I've done the upload.
Edit: I tried this again, and I received the email notification. I used a slightly different set of flags for dpkg-buildpackage the second itme:
dpkg-buildpackage -S -sa -rfakeroot -tc -D -k4C8A14AB
I'm trying to use Axis2/Java to consume web services. In particular, I'm trying to generate Java skeleton code from a WSDL file.
I installed the libaxis-java package, but the package doesn't contain the WSDL2Java.sh script I was expecting. I tried to generate the Java code by doing:
java -cp /usr/share/java/axis.jar org.apache.axis.wsdl.WSDL2Java foo.wsdl
But I get the following error:
