Please, always share the error messages. Ask yourself, why you realized it was a failure and share that information. Not just here, everywhere on the internet if you expect some help. Otherwise the only thing we can tell you is that āif something went wrong, then something has to be doneā.
If you share those messages by copy-pasting them from a terminal, it is a good practice to use the </> button above the text area to make it a codeblock. In case of a simple text using the quotation mark button to quote the message would be enough.
Sharing codes and copy-pasted messages also helps us to understand what you really want to do even if you could not describe your issue properly.
