I'm running Magento 2.4.2 and I'm using Composer v2.0.11. 2 days ago, after running, as usual, composer update, I suddenly received this error:

[ErrorException]
chmod(): Operation not permitted

You can see composer update -v output down below:

enter image description here

What I tried

  • I tried to apply chmod -R 777 . and chown -R www-data:www-data .
  • I tried to apply chmod u+x bin/magento

Any ideas?

Setting the filesystem ownership to the magento user (dev in my case, while before was assigned to www-data user) fixed the problem: chown -R dev:www-data .

  • Be sure to undo your chmod command if you successfully executed it, 777 permissions on the whole Magento filesystem is potentially very dangerous

  • Yeah, thanks for point this out. In developer mode I set them like this as described in the Magento doc: cd /var/www/magento && find . var generated vendor pub/static pub/media app/etc app/code app/design -type f -exec chmod g+w {} + && find var generated vendor pub/static pub/media app/etc app/code app/design -type d -exec chmod g+ws {} + && chown -R :www-data . && chmod u+x bin/magento
