Magento refuses to upgrade 1.4.2.0 ===> 1.5.0.1

This is my first time using Magento. I upgraded this site from 1.4.1.1 to 1.4.2.0 without issue. Now trying to go to 1.5.0.1 it just seems 开发者_如何学JAVAto refuse at every turn. I tried by entering this key into Magento Connect: magento-core/Mage_All_Latest

And it says this: Ignoring installed package magento-core/Mage_All_Latest Nothing to install

I tried to upgrade via SSH and got this: Attempting to discover channel "magento-core"... unknown channel "magento-core" in "magento-core/Mage_All_Latest" invalid package name/package file "magento-core/Mage_All_Latest" Cannot initialize 'magento-core/Mage_All_Latest', invalid or missing package file Package "magento-core/Mage_All_Latest" is not valid install failed

In the downloader I noticed a the downloader had a version 1.5.0.0 upgrade available. I thought maybe I needed the newest downloader before I could update all the packages. I upgraded just the downloader to 1.5.0.0 which worked. Then I tried the full upgrade again and now it is mega retarded with this: Couldn't resolve host 'magento-core'

That’s cute isn't it? So I gave it once last whirl at the ssh console and i get this bad boy: Attempting to discover channel "magento-core"... Attempting fallback to https instead of http on channel "magento-core"... unknown channel "magento-core" in "magento-core/Mage_All_Latest" invalid package name/package file "magento-core/Mage_All_Latest" install failed

I tried a forcing it via SSH but still no love. I reverted from a backup I made so I do not have downloader 1.5.0.0 any more. Now of course I am back to square one with it telling me there is nothing to install when I try to update via MC. When I check in MC if there are any updates available it lists these two: Mage_All_Latest Upgrade to 1.4.2.1 (stable) Metapackage for latest Magento 1.4 release And the Mage Downloader 1.5.0.1 but I already installed these before and it did no good so I restored my backup before the failed update.

I was trying to ask this question Magento's Forums but they are a mess right now. Their captcha fails and threads close on their own so you get little to no help. I wouldn't be surprised if they did this on purpose in concert with their 1.5.0.1 release.

Go to the root of your website and execute these commands (Where index.php is):

wget http://www.magentocommerce.com/downloads/assets/1.5.0.1/magento-1.5.0.1.tar.gz

tar -zxvf magento-1.5.0.1.tar.gz

Skip the next 4 commands if you have your magento install in a folder called Magento:

cd magento

cp -rf * /home/bitscom/public_html

cd ../

rm -rf magento

rm magento-1.5.0.1.tar.gz

For a detailed explanation see my post on the offical magento forum: here My name is Veracious on there.

If your SSH account is anything other than your apache user (i.e.: root. you will get error 500 when trying to access the site do the the permissions on the new files you just extracted. To resolve that use chown and chgrp. For a detailed explanation once again see my post: here

I think the location for the upgrades have changed. Instead of the: magento-core/Mage_All_Latest use: community/Mage_All_Latest

As what mrdon has mentioned.

I couldn't upgrade through Magento Connect either. I followed these instructions for installing magento and it worked fairly well. I changed line 3 as below to copy the folders/files over my existing ones.

wget http://www.magentocommerce.com/downloads/assets/1.5.0.1/magento-1.5.0.1.tar.gz
tar -zxvf magento-1.5.0.1.tar.gz
cp magento/* magento/.htaccess .
chmod -R o+w media var
chmod o+w app/etc

I followed the instructions from the following post to upgrade from 1.4.1.1 to 1.5.0.1:

http://www.magentocommerce.com/boards/viewthread/219720/#t301761

Then flushed the cache and reindexed everything. Everything worked.

Don't forget to change magento folder ownership to your web server user. In my case I had to run

chown -R www-data:www-data /var/www/magento
