Answer 1

for nginx people
if you have php-fpm installed you have to tell it that its user and group is nginx. /etc/php-fpm.d/www.conf . find user which is assigned to apache by default and change it to nginx. also do it for group. then run this command :

sudo service php-fpm restart

also inside of your wordpress directory execute these commands

sudo chown nginx:nginx * -R 

sudo usermod -a -G nginx username

change username into what your current username is.

yet you have to apply propper permissions. run these commands inside your wordpress directory

sudo find . -type f -exec chmod 664 {} + 

sudo find . -type d -exec chmod 775 {} +

(Re)setting the permissions via ftp didn't make a difference for me either. There is no SSH available, so I had to log in the control panel (directadmin in my case), the File Manager where I could "Reset Owner" to "File ownership reset" the /wp-contents directory.

Answer 3

I'm running Nginx with Wordpress. I deleted the upgrade folder in wp-content and then ran the upgrade from the wordpress GUI again. I noted the linux user for the upgrade folder created was www-data. I then did a {sudo chmod -R www-data:www-data .} Ran the upgrade again from the GUI and it worked.

Probably need to change the permissions on most of the folders so they can't be modified by www-data but I'll figure that out tomorrow.

Answer 4

A permission issue, make sure apache (www-data) has write permissions.
