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 downloading symfony-1.4.0.tgz ... Starting to download symfony-1.4.0.tgz (3,145,121 bytes) ............................................ ............................................ done: 3,145,121 bytes upgrade ok: channel://pear.symfony-project.com/symfony-1.4.0 rp@devbox:/usr/share/php/symfony$
Hope this helps someone else trying to upgrade as well.
