Hi I am running the perfect server installation of ispconfig + nginx + ubuntu 18.04, and I am running multi php ver 7.2, 7.4, 8.1 when I tried to install redis extension for all php ver, only php7.2 works. I could not install redis extension for php 7.4 and 8.1 ver. root@ECS1:/# sudo apt install php8.1-redis Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package php8.1-redis E: Couldn't find any package by glob 'php8.1-redis' E: Couldn't find any package by regex 'php8.1-redis' root@ECS1:/# sudo apt install php7.4-redis Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package php7.4-redis E: Couldn't find any package by glob 'php7.4-redis' E: Couldn't find any package by regex 'php7.4-redis' Google and found below discussion saying that I need to upgrade to Ubuntu 20.04.6 LTS in order to achieve these. would it break my existing ISPconfig setup? it seems a very high risk upgrade. https://forum.hestiacp.com/t/problem-install-redis-module-php/11845/5 thanks
You need to use a repository that has the packages in question or install them manually. I reccomend using https://deb.sury.org/
Well i forget that this repo does not provide support for 18.04 anymore. Well you should consider upgrading anyways.
