8195,Plugin Installer  failed,tsingzero,,"defect on 2.7-beta2-9638
2.7 beta1 doesn't have this problem.

in some enviroment, the working_dir on the host will be something like: /home/user/www/site/wp-content/upgrade and plugins_dir: /home/user/www/site/wp-content/plugins

but in the ftp context, the working_dir will be: /www/site/wp-content/upgrade and plugins_dir could be: /www/site/wp-content/plugins.

So, in the wp-admin/includes/plugin-install.php, function wp_install_plugin has the call:
$res = update_pluginfiles_base_dir($working_dir . '/' . $filelist[0], $plugins_dir . $filelist[0]);

if we install the plugin: all-in-one-seo-pack

will be: $res = update_pluginfiles_base_dir(""/www/site/wp-content/upgrade/all-in-one-seo-pack"", ""/www/site/wp-content/plugins/all-in-one-seo-pack"");

and in the function: update_pluginfiles_base_dir($from, $to):
it will call: $files = list_files($from), which would opendir(""/www/site/wp-content/upgrade/all-in-one-seo-pack""), then if will fail.
