If you are hosting your blog on WordPress then you might have seen this error “An automated WordPress update has failed to complete” sometime or other. This usually happens when you install a plugin, upgrades or any WordPress installations which disrupts in between. This error shows up above the WordPress main dashboard. This happens because WordPress creates a .maintenance file inside your host where you have hosted your WordPress. This file keeps the entry of this error message and as a result it displays every time even after it has been rectified.
You can resolve this by simply deleting the .maintenance file from your host. Once deleted check back your WordPress dashboard again. You will find the error disappeared.
