Upgrading a Xen Virtual Private Server from Ubuntu 7.04 (Feisty) to 7.10 (Gutsy)


For the last two years, I have been running a Xen based VPS which has Ubuntu server on it. Up to last week, it was running Feisty Fawn (7.04), and it was time to upgrade it to Gutsy Gibbon (7.10), the latest Ubuntu version.

The upgrade had some complications, so I am documenting them here in case someone has the same problem.

Procedure for upgrade

On Debian and earlier versions of Ubuntu, the procedure for upgrading consisted of entering the commands:

OLPC received well in a remote Peru village of Arahuay


The OLPC has started deployment to schools in some countries.

The way the students interact with it, learn how to use it, and interact to each other is already amazing. There are stories of school drop outs coming back to school for the sake of the laptop, aggressive kids who become experts in the OLPC, and help others out using it, and more.



A Toronto company put out a job on for Flash developers. The candidate should know Lynux though. What exactly is that?

If everyone pronounced Linux the way Linus does (Lee-nooks), rather than the Anglicized (Lie-nooks) this would not have happened.

Bell Canada and Rogers laptop connection cards provide internet access anywhere (Linux?)


Two wireless providers in Canada started offering laptop access via PC cards.

Bell Canada has introduced laptop cards that provide internet connectivity anywhere in coverage areas. The ads tout the fact that they can be used in a cab or on a train.

These cards use the mobile phone frequencies and data infrastructure (EVDO).

The monthly unlimited plan is $75 which is reasonable.

Ubuntu Edgy 6.10 to Feisty 7.04 upgrade: sound and video issues


Since late November 2006, I had Ubuntu Edgy 6.10 running on my Toshiba Satellite A100-TA6. I wrote a full report on that here.

So, I decided to take the plunge and upgrade to Feisty 7.04, and so the adventure begins.

Ubuntu Linux backup of a laptop using a USB enclosure and the dump utility


Earlier, I wrote about how to use a USB 2.0 hard disk drive enclosure for backup.

In this article, I explain how to use that hard disk using the dump utility.

The dump utility

The dump utility is one of the oldest commands for backup on UNIX system, but not one that is widely used in home and small business Linux systems.
