Answer 1

Execute bellow commands

sudo chown -R www-data:www-data /wp-content/plugins/
chmod 777 /wp-content/upgrade/

open your wp-config.php file and place bellow line.
define('FS_METHOD','direct');

Answer 2

This error is due to the absence of permission given to the wordpress files. All the folder permissions should be 755.

chmod -R 755 /for all folders

And all the file permissions should be 644.

chmod -R 644 /all the files

You can also check the wordpress GUI and check the site health(Tools > site health)if your health status is not good, scroll down and see the errors over there,needed permission for each file will be mentioned over there and give the permissions accordingly.

Only for try

chmod -R 777 /parent folder where all the files are included if this works you can confirm that your issue is with the permission.If that didnt work check out the memory and the wp-config.php file

Answer 3

If you are using WP-CLI you could try the command below: sudo wp plugin install [plugin name] --allow-root

This helped me solved the same problem as yours before.
