Yesterday I tried to install php-gd for php7.2.15 on Ubuntu 18.04 lts. Today when Ubuntu got updated it installed php5.6 php7.0 php7.1 php7.3 beside my php7.2. I think I did something wrong but now I just don’t want these versions on my server It’s a server holding website and app so can’t play with it, php -v now shows:

PHP Warning: PHP Startup: Unable to load dynamic library

But phpinfo file is normal not mentioning anything irregular and everything is functioning like normal, but I’d like to keep my server clean so any advice?
