Hi,
What is the best way to run OpenCATS locally?

I have tried on Ubuntu 16.04 WSL and Docker. where I generally get to this
root@f45c499c7ae4:/# apt-get install php5.6 php5.6-soap php5.6-ldap
Reading package lists... Done
Building dependency tree
Reading state information... Done
Note, selecting 'php5.6-json' for regex 'php5.6'
Note, selecting 'php5.6-common' for regex 'php5.6'
E: Unable to locate package php5.6-soap
E: Couldn't find any package by glob 'php5.6-soap'
E: Couldn't find any package by regex 'php5.6-soap'
E: Unable to locate package php5.6-ldap
E: Couldn't find any package by glob 'php5.6-ldap'
E: Couldn't find any package by regex 'php5.6-ldap'
I have also tried to install on W11, but ran into issues with the extensions for reviewing resumes.

Thanks!

Hi, I'd use PHP 8.2 and use the pHP8.2 branch at the moment.

I use the OpenCATS Docker Setup. This is currently the most stable and maintainable way to run OpenCATS locally, as it handles PHP 5.6 and required extensions for you.

I was trying docker setup, initially tried getting using opencats/opencats:0.9.5, but it is getting nginx error, so I started build my own image, followed below steps,
downloaded latest release fill zip opencats-0.9.7.4-full.tar.gz
then extracted the contents
then created compose file under the extracted folder, following instructions from https://documentation.opencats.org/tech ... structions
then docker-compose build failed saying Dockerfile not found, I have created DockerFile, but used from image as FROM opencats/php-base:7.2-fpm-alpine-mcrypt
then build failed again saying that image is linux, and apt-get wont work. This base image is Linux and all commands in docker file from instructions is ubuntu, is there any reference to latest docker file or release images that works, I really appreciate any help

Here is the error when running opencats/opencats:develop
