When WordPress goes to update, it creates a lock in the database so that multiple users and processes do not attempt to edit the system in parallel. However, there are cases when this lock is created, but the update never occurs. If this happens and the lock is not released, you will be blocked from retrying until you manually clean up the lock.

The lock is created in the database in the wp_options table. You need to find the option with the option name core_updater.lock and delete the row. Then you can return to the site and run the update again.

Problem:

I was trying to get Resharper’s dupfinder to run from a command line script.  Using Resharper’s command line tools. I keep getting the  errors below.

The solution came from https://devnet.jetbrains.com/thread/460601;jsessionid=FB59ACB66FFC17A22451A99A63A1BD76 which basically says

Remove Zone.Identifier NTFS Alternate Data Stream (http://msdn.microsoft.com/en-us/library/dn392609.aspx) from the ZIP file before using it.

turns out it was spot on. I used 7Zip instead of windows built in Zip extractor. Everything worked after that.

Error I received:
