This is user’s permission problem that will be solved by method given below that worked for me.

step-1 : First open wp-config.php file of your wordpress installation folder.
step-2: Copy below code and paste it at the end of the wp-config.php file.

define('FS_METHOD','direct');

step-3: Now open your droplet access console and enter root as username and its password.
step-4: Copy below code and paste it into access console where you have to specify your plugin directory path and then hit enter.

chmod 777 /yourwebsitename/public/wp-content/plugins/

Note: Replace your website name in the place of yourwebsitename.
Thank you.

After you upload your files, you’ll want to make sure ownership permissions are set to Apache so that Wordrpess can update and/or install plugins without requiring FTP credentials. You can set permissions via SSH.

Single site hosting:

chown -R apache:apache /var/www/html

Multi site hosting:

chown -R apache:apache /var/www/

You may need to do this whenever uploading folders.

define(‘FS_METHOD’, 'direct’);
This worked for me too.

use this code , wordpress asking for ftp details because wordpress doesn’t have permission to write in your server.
use these two commands in terminal.

$sudo a2enmod rewrite
$sudo chown -R www-data /var/www

ryanginx that worked for me too. thx!!

Please, I run `sudo chown username:www-data /var/www -R
sudo chmod g+w /var/www -R but don’t work to me.“`

How should I replace the commands??? Sorry, I’m beginner…

I insert

define('FS_METHOD', 'direct');

And too not works…

Thanks It’s works

sudo chown username:www-data /var/www -R

you can login width root and Type the command: “`

sudo chown -R {path}

• {path}: is path to your website, ex: /home/admin/domain/mywebsite.com ”`

Please try to use 755 for more safer.
Thanks for this excellent answer. I have done by 755.

I had the same problem and the solution above (wp-config.php and chmod) is not working for me.
For me, the trick was PHP execution mode. I just changed it from mod_php to FPM in server settings, and it works like a charm now.

If this is your test rig or going to use it only as a local host you can change the user and group configuration to your user then you do not need the define('FS_METHOD', 'direct'); code to be added in the wp-config.php file.
use the following command to open the apache2 envars file

sudo nano /etc/apache2/envar

Once the environment variable file is opened scroll to section where you will find

export APACHERUNUSER=www-data
export APACHERUNGROUP=www-data

replace the “www-data” with your user name example “user”.

This should fix most of the problems for you
With this you have added the user as Apache2 owner so setting default chmod to 755 or 750 for directories and 644 for files should work without any error.
