问题
In my store have magento community edition - 7.1.
I try to install extension using magento store, but I got an error like this for all type of extensions
community/Dropifi_Dropificontactwidget: Could not resolve host: connect20.magentocommerce.com; Host not found
I placed this key for install magento
http://connect20.magentocommerce.com/community/Dropifi_Dropificontactwidget
http://connect20.magento-commerce.com/community/Dropifi_Dropificontactwidget
Help me to get a result for this issue.
Thanks

This was not an issue specific to you. Today, the Magento Connect server experienced an outage which prevented any of the community extension keys from working.
The Connect server appears to be online now, so try again and it should work.

Helpful Note:
You can download extension packages directly by using the following tool:
http://freegento.com/ddl-magento-extension.php
Just paste in your Magento extension keys and Submit. A downloadable link will appear for you to obtain the package.

I had the same problem ("CONNECT ERROR: Unsupported resource type") while upgrading a 1.6 magento on PHP 5.5.
The unpack function (http://php.net/manual/en/function.unpack.php) has changed.
In downloader/lib/Mage/Archive/Tar.php, the line
const FORMAT_PARSE_HEADER = 'a100name/a8mode/a8uid/a8gid/a12size/a12mtime/a8checksum/a1type/a100symlink/a6magic/a2version/a32uname/a32gname/a8devmajor/a8devminor/a155prefix/a12closer';
must be replaced by:
const FORMAT_PARSE_HEADER = 'Z100name/Z8mode/Z8uid/Z8gid/Z12size/Z12mtime/Z8checksum/Z1type/Z100symlink/Z6magic/Z2version/Z32uname/Z32gname/Z8devmajor/Z8devminor/Z155prefix/Z12closer';
