No releases for package "magento-core/Mage_All_Latest" exist



I'm moving a customer website from version 1.3.1 to the most 1.9.X recent one.

I made some tests last december and I was able to do the upgrade (1.3.1 -> 1.4.2 - >


Before doing the upgrade on the new production server, I wanted to do a blank run to check if everything was well configured.

For the upgrade from 1.3.1 to 1.4.2, with the command :

./pear upgrade -f magento-core/Mage_All_Latest-stable

 it returns that error:

No releases for package "magento-core/Mage_All_Latest" exist
Cannot initialize 'channel://', invalid or missing package file
Package "channel://" is not valid
upgrade failed

So I checked with the server I used last December and I am encountering the same error.


Did some have an issue for this problem ?


Thank you for your help.
