Upgrading to symfony 1.4

To typically upgrade the version of symfony, I usually run the command

# sudo pear upgrade symfony/symfony

But it seems that the channel details have updated you would require updating that first and then you can upgrade to symfony 1.4. This is what i did.

rp@devbox:/usr/share/php/symfony$ sudo pear channel-update pear.symfony-project.com
Updating channel "pear.symfony-project.com"
Update of Channel "pear.symfony-project.com" succeeded

rp@devbox:/usr/share/php/symfony$ sudo pear upgrade symfony/symfony

rp@devbox:/usr/share/php/symfony$

Hope this helps someone else trying to upgrade as well.
