Get rid of “Another update is currently in progress” in WordPress

When you updating one of your resources in wordpress, accidentally you close the window (that’s what I did).

Then when you try to update it again, there is still another process already running. You need to get rid of this before you continue.

Use wp-cli:

wp option delete core_updater.lock
