Nextcloud version : (probably 17 but cannot determine now sa occ error)
Operating system and version : 18.04
Apache or nginx version: Apache/2.4.29 (Ubuntu)
PHP version (eg, 7.1): 7.3 installed previous was 7.2

The issue you are facing:

Is this the first time you’ve seen this error? (Y/N):

Steps to replicate it:
updated php 7.2 to php 7.3
then restart apache2

  1. root@localhost # sudo -u www-data which php /var/www/html/nextcloud/occ files:scan --path “skumar/files/Educational/Tutorials/” -vvv
2

Wouldn’t it be a good start to post the error message your getting? I’m sorry, but with the given description no-one can really give you any valuable advice, except that you should double-check the shared command syntax. Executing the which command on php will only return the php path and perhaps some errors not execute the occ command itself :wink:

apologies, I managed to fix the error myself, there were some php dependencies missing. which after I installed it started to work.
thanks.
