1.5 hours to upgrade Ubuntu from 8.04LTS to 8.10.

All done yesterday night.

If you are using 8.04 (Hardy) then you can update directly to 8.10 (Intrepid). In other cases you should follow a sequential upgrade path and not skip any of the releases (unless you are on a LTS release).

• “Backup important files”. Although the upgrades preserve your data and settings, it’s always wise to backup at least your home directory in case Murphy’s law comes into play.
  • This includes copying (or tar-ring) the desired files to an external drive or a server some place safe. If you plan to do incremental backups in future as well then use something like rsync to help you out. (Backup Tutorial)
• Make sure your system is up to date.  This means that you should have applied all the available updates for your present version of Ubuntu (these updates are different from the actual upgrade. So be careful you don’t skip this step).
• Read the Release Notes to find out if there are some issues and possible workarounds and to know what’s the new release all about.
• Upgrade by running the Update Manager (Note that before 30th October you will have to run ‘update-manager –devel-release’ to let it know you want to install the developmental release)

So, it is not that hard. You only need a little bit caution before upgrading.

Are you ready? Do upgrade tonight.

Ubuntu 8.10 Desktop Edition delivers the features you need for an increasingly mobile digital life, including 3G wireless support and guest sessions that lets users temporarily share computers without compromising security.

Ubuntu 8.10 Server consolidates its support for virtualization with an integrated Virtual Machine builder, and brings with it a fully-supported Java stack and support for per-user directory encryption.

Do you wait for it? I am.

Some people said Ubuntu is not good enough and it is a bad guy of Linux world. It is harmful to the other Linux distributions.

I agreed with them in one point only. It is not good when you find the computer failed to boot after upgrading.

It happens all the time doesn’t it? You need to unmount a CD or you want to pack away the external drive but when you try to umount it you get the dreaded “device is busy” message. Wouldn’t it be great if Linux actually told you what was keeping the drive busy? Here we are in 2008, I’m using Ubuntu Gutsy, and that message hasn’t changed in all the years I’ve used Linux.

# umount /media/disk/
umount: /media/disk: device is busy
umount: /media/disk: device is busy

First thing you’ll do will probably be to close down all your terminals and xterms but here’s a better way. You can use the fuser command to find out which process was keeping the device busy:

# fuser -m /dev/sdc1
/dev/sdc1: 538
# ps auxw|grep 538
donncha 538 0.4 2.7 219212 56792 ? SLl Feb11 11:25 rhythmbox

Rhythmbox is the culprit! Close that down and umount the drive. Problem solved!

The real name of this file is Apache’s directory-level configuration file .

There are three major usages of .htaccess.

1. Authorization, authentication: .htaccess files are often used to specify the security restrictions for the particular directory, hence the filename “access”. The .htaccess file is often accompanied by an .htpasswd file which stores valid usernames and their passwords.
2. Customized error responses: Changing the page that is shown when a server-side error occurs, for example HTTP 404 Not Found.
3. Rewriting URLs: Various server-side PHP scripts use .htaccess to rewrite “ugly” URLs to shorter and prettier ones.

The authorization can restrict the right of access to different directory or by different user right.

Customized error page is also very important for the site which want to provide better user experience.

Rewriting URLs, is used so popularly on all kind of PHP drived programs, such as WordPress.

More detailed usage of .htaccess, please go to Apache Tutorial, and Httpd wiki.
