One more thing beofre making the above modifications. First modify the permissions to 777 to total magento application. Then after installing the extension rollback the permissions to 755 — Pavan Kumar, Jul 15 '14 at 10:21

what is the path for your magento application in your linux SSH server? — Pavan Kumar, Jul 15 '14 at 10:26
That is a permission issue, please check that your magento root directory has write permissions — Amyth, Oct 23 '15 at 06:57

To solve this problem, follow the steps below (I suppose you are using Ubuntu):

1) sudo chmod -R 777 /var/www/html/magentoInstallationFolder/

2) Install Magento Extension

3) Restore correct permissions for directories and files respectively

sudo find /var/www/html/magentoInstallationFolder/ -type d -exec chmod 775 {} \;
sudo find /var/www/html/magentoInstallationFolder/ -type f -exec chmod 664 {} \;

Read more about why 777 permissions are bad and you need to restore good permission code (775) after you install the extension: https://askubuntu.com/a/30635

Magento tries to put the maintenance flag in the root directory. Here is the code that does it:

<?php
//downloader/Maged/Controller.php::startInstall()
if ($this->_getMaintenanceFlag()) {
...
//downloader/Maged/Controller.php::isWritable()
$this->_writable = is_writable($this->getMageDir() . DIRECTORY_SEPARATOR)

If you can't change magento root directory permissions just uncheck "Put store on the maintenance mode while installing/upgrading/backup creation" flag.

That was the right solution for me; settng crazy 777 file permission should never be. – nicolallias Feb 13 '17 at 10:17

There's a couple of suggestions to change the permissions to this:

sudo chmod 777 -R /var/www/html

Which is a really really bad idea. Have a search for 'Magento permissions' and follow the guide instead. Unless you're seeking to get your site hacked wihin a few minutes.

chown -R www-data:www-data /var/www/your_magento_folder That did the tick for me, don't change the owner of the www folder

Type the following command in your terminal.

sudo chmod 777 -R /var/www/html/<magento folder name>. Press Enter.

Then it will ask for password if exists for your username.

Once it is done, login and logout the admin and try to install extension which you want

Edited:

Try this for your files:

sudo chmod 777 -R /var/www/html

and follow the above steps.
