WordPress Update Failed Error
Downloading update from https://wordpress.org/wordpress-5.9.zip… Unpacking the update… Could not copy files. Installation Failed
The auto-update failed because of the server problem generally. When these errors happen, a blank white screen would be shown, and after sometimes an updated failed notice would be given.
If you see the “WordPress Update Failed” error when trying to update WordPress, it usually means that your server cannot connect to WordPress.org at the moment.
Here are some potential solutions:
- Try updating again in a few minutes. If the error persists, try again later.
- Check if WordPress.org blocks your server’s IP address.
- If you’re using a shared server, check with your host to see if they block any outgoing connections to WordPress.org.
- Try updating WordPress offline. See the instructions here: Updating WordPress Offline
- If none of the above solutions work, it’s possible that your WordPress files are corrupted. Try re-installing WordPress from scratch.
