If you have your own Ubuntu server running you may encounter the maximal file size upload limit in php scripts which is set to 2Mb as default. In order to change that we first have a look what the size actually is. In /var/www (standard www directory) create a file called info.php with the following content:
<?php // Show all information, defaults to INFO_ALL phpinfo(); ?>
Then browse to this file via http://localhost/info.php (replace localhost with the servername if necessary) and look for the line
upload_max_filesize 2M 2M
which will show you the actual maximum file size. In order to change that open a ssh connection to your server and edit the file /etc/php5/apache2/php.ini with
sudo nano /etc/php5/apache2/php.ini
search for “upload_max_filesize” with Ctrl-W and change “2M” to “20M”. Save the file with Ctrl-O and exit with Ctrl-X. Restart the apache server with
sudo /etc/init.d/apache2 restart
and visit again http://localhost/info.php to check if the maximum file size was changed.

While is may be common sense to some, for those people new to messing around with servers, don’t forget to restart Apache for the changes to take effect.
You can use this line to do so:

Thanks this helped me to upload larger extensions on local TYPO3 sites.
