As I have tried to install this repo manually, add-apt-repository ppandrej/php and it's timing out. There seems issue with this repo any alternate solution to install ISPconfig?

Exception occurred: ISPConfigOSException -> Command add-apt-repository -y ppandrej/php failed. (/ispconfig.ai.php:15)

 

After running the command below to disable IPv6, ISPConfig installs successfully, and the repository works as expected. The service provider has confirmed that IPv6 is not enabled on the server, and the network is functioning normally.
sudo sysctl --write net.ipv6.conf.all.disable_ipv6=1

 

ISPconfig3 has been installed successfully....
