theme and plugin install

what happens if you manually create the upgrade folder?

Sounds like a permission issue on your server.

I found this interesting tibdit when googling your error:

ome plugins require the /wp-content/ folder be made writeable, but in such cases they will let you know during installation. In some cases, this may require assigning 755 permissions or higher (e.g. 777 on some hosts). The same is true for /wp-content/cache/ and maybe /wp-content/uploads/

I manually created the subfolder “upgrade” but the system is then unable to create and subfolders from there for the plugins and or themes.

Could not create directory. /var/www/wordpress/wp-content/upgrade/headspace2.tmp

contentpig, did you ever resolve your issue. I am having the same issue.

I have this problem too.
I appreciated if someone can help me

Maybe you should try this:open your ftp configuration file,make #write_enable=YES to write_enable=YES.
