Try clearing the cache yourself, and give it a try again.

Hmm! Do this instead:

> sudo -u **username** php /path/to/mautic/bin/console cache:clear

Change the username to the mautic directory user, and the /path/to/mautic to your mautic directory.

I still have the same error, i think the console is broken,  
if i just do php bin/console, i get the same error…

If that is so, then you might want to update it manually. Steps are here [https://docs.mautic.org/en/troubleshooting/update-failed](https://docs.mautic.org/en/troubleshooting/update-failed)
