Getting Error during Upgrade


I am trying to upgrade nextcloud 11.0.1 to 11.0.5 and when I run the following command it giving error. I wonder if someone can help me.

sudo -u www-data php /var/www/html/nextcloud/updater/updater.phar

sudo: unable to resolve host cloudwebserver1
PHP Warning: PHP Startup: Unable to load dynamic library ‘/usr/lib/php/20151012/’ - /usr/lib/php/20151012/ cannot open shared object file: No such file or directory in Unknown on line 0
Nextcloud Updater - version: 1.0.3

Step 5 is currently in process. Please call this command later.
