I have Ubuntu 16.04 LTS running with PHP7 and phpmyadmin installed. However, I get a lot of deprecation notices like:
Depre
For PHP 7.3+
Edit the following file : config.inc.php. It can be located in /etc/phpmyadmin/config.inc.php or in /usr/share/phpmyadmin/config.inc.php
/**
* Whether or not to query the user before sending the error report to
* the phpMyAdmin team when a JavaScript error occurs
*
* Available options
* ('ask' | 'always' | 'never')
* default = 'ask'
*/
$cfg['SendErrorReports'] = 'never';
