Normally Magento install theme can be done from the Magento Connect. But recently in our Magento installation service we used to get tickets complaining that the customers are not able to install Magento Blue theme via Magento Connect. When you try to install you may get the below error.
ERROR: Via magento connect magento-core/Interface_Frontend_Default_Default_Blue requires package "magento-core/Interface_Frontend_Default" (version >= 1.3.1, version <= 1.4.0, excluded versions: 1.4.0), installed version is 1.4.0.0 Install Errors No valid packages found PEAR ERROR: install failed magento-core/Interface_Frontend_Default magento-core/Mage_Core_Modules
To fix this, login to your account via SSH and navigate to the Magento installation folder and execute the below command.
Install Interface_Frontend_Default correct version
./pear install magento-core/Interface_Frontend_Default
And then the Blue theme
./pear install magento-core/Interface_Frontend_Default_Default_Blue
You can get help for pear command by executing
pear help
And to list Channels
pear list-channels Registered Channel
