I've seen many similar questions but whatever I tried so far wasn't successful.

I installed PHP in different versions and in parallel from an PPA. This is exactly how I want it.

But now I have some older, unmaintained versions of PHP installed on the system (I even can see e.g. an /etc/php/php5.6 folder with content though php5.6 -v claims it's not installed, but php7.0 -v still works e.g.).

How to get rid of specific older versions and their extensions.

apt purge etc. did not help and I want to keep the PPA for future versions.

EDIT Looking at the list of installed PHP packages I doubt it's installed from the PPA?

PHP 5.6 is no more installed and its configuration files are no more tracked by the package management system APT/dpkg. If it were, dpkg -l would produce a line starting with rc for it. So you can simply rm the remaining tracks of PHP 5.x found on your machine. (Note: Taking a backup before removing files is advisable.)

The versions 7.0, 7.2, 7.3 and 7.4 are installed using APT/dpkg on your machine and you can use the package management system’s tools to uninstall them, e.g. apt purge. The command to remove everything related to PHP 7.0 would be:

sudo apt purge php7.0\*

Note: Check what is going to be removed before proceeding.

  • thanks. So though other files might have been installed these tracks needs to be removed manually? Is there a simple way to identify them as they must have been part of the install process? – LBA Jan 27 '20 at 12:57
  • @LBA Configuration files (mostly stored in /etc) should be removed in the purge process. I cannot tell you retrospectively why /etc/php/php5.6 was not removed in your case. Maybe you had a local modification there? The purge command might have told you the reason when you uninstalled PHP 5.6 using APT in the past. – Melebius Jan 27 '20 at 14:15
