Not able to install any new plugins

Hi, I’m new on wordpress and I’m trying to install few plugins but not able to install them, getting following error.

“Downloading update from http://downloads.wordpress.org/plugin/wp-multibyte-patch.1.6.2.zip…

Unpacking the update…

Could not create directory. /home/vol4/hosting.net/fees1_domain009/example.com/htdocs/wp-content/upgrade/wp-multibyte-patch.tmp/wp-multibyte-patch“

What should I do to deal with this issue?
