Causes and fixes for magento 'connect error: unsupported resource type' error

When we try to update extensions in Magento Connect/Magento Connect Manager or try to install a new package we receive following error:

"CONNECT ERROR: Unsupported resource type"

This could happen due to a number of reasons.

Usually, manual installation will work without any issues.

You can perform the manual installation following below steps:

i. Firstly, download extension.

ii. Then, unzip package.

iii. Next, copy Eightdigits_MarketingSuite/app to MAGENTO_HOME/app:

./mage sync (you need to make ./mage executable if it was not : chmod 750 mage)

iv. Clean cache on Cache Management page of Magento admin dashboard.

v. Then, log out and log in to Magento Admin.

vi. Then, refresh Magento store page so you could see 8 digits comments in page source.

1.PHP version issues

2. Browser issues

This could be due to browser issues.

Please try it on a different browser as this is probably related to internet connection or the downloader.

3. Package extraction

At times, this could be an issue with extracting the package.

On some magento installation, users have this problem.

If you get it please download the package to the Magento directory and then try extract package *.tgz and upload files via ftp manager to your site.
