Failed AppStore download

I have tried to download an update from the AppStore for Yosemite 10.10.4 and unfortunately it interrupted.

Now I am in a situation where if I try the update again I get the following message:

Some updates need to finish downloading before they are installed.

If I confirm with

Download & Restart

it will tell me it is rebooting the computer but then et another message saying:

Available updates have changed

If I confirm that one too it will just go back to the previous message.

It is some sort of infinite loop.

I have tried updating through the Terminal with:

softwareupdate

command but the result is the same.

MacBook Air, OS X Yosemite (10.10.3)

This procedure will delete certain temporary and cache files used by system processes. The files are automatically generated and don't contain any of your data. Occasionally they can become corrupt and cause problems such as yours.

Back up all data before proceeding.

Triple-click anywhere in the line below on this page to select it:

/var/folders/zz

Right-click or control-click the highlighted line and select

Services ▹ Reveal in Finder (or just Reveal)

from the contextual menu.* A folder should open with a subfolder named "zz" selected. Move that subfolder to the Trash. You may be prompted for your administrator login password. Restart the computer and empty the Trash.

*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select

Go ▹ Go to Folder...

from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
