Kali无法安装不同版本的php

Question

I have php 7.3 running on kali but I need to downgrade to 7.1 to accommodate an old library.

When I run sudo apt-get install php7.1 I get an error saying there is no installation package found. This happens for every version of php I try.

Is there any reason this might be happening?

Answer 1

Try this

$ sudo apt-get -y install php7.0 libapache2-mod-php7.0

//Restart the server

$ systemctl restart apache2

---

If first method will not work for you then enter this command to update and upgrade all kali environment and tools

apt-get clean && apt-get -y update && apt-get -y upgrade && apt-get -y dist-upgrade && apt autoremove

After running this command run this again

$ sudo apt-get -y install php7.0 libapache2-mod-php7.0

Hope this will solve your issue

Answer 2

Execute this in your console

a2dismod

and chose the version of php you wish to disable, then execute

a2enmod

and chose the php version you wish to enable in your Apache server. Finally just restart you apache with:

service apache2 restart
