**Your software**  
My Mautic version is:2.16  
My PHP version is: 7.3

**Your problem**  
My problem is: Updating via button was stuck at clearing cache. I exited and now tried a different method.

These errors are showing in the log: NA

Steps I have tried to fix the problem:

I followed these steps and reached this point.

php /var/www/html/app/console doctrine:migration:migrate

I then get this error when it runs:
