You should be able to uninstall frappe-bench using pip, and remove the frappe-bench folder from your home directory. Install docker-ce using apt and follow the instructions to install frappe found here.
Is it possible to remove the server completely, and deploy a new one or do you have other systems running on there? I would migrate the database and deploy new server.
@smino If he went through all the steps in the install guide there is quite a lot of clutter like a mariadb server, redis, etc. already running on the system. It will be easier to migrate to new deploy to avoid future errors.
Yes I have all the mariadb, redis, etc installed, I don’t have a problem to reset my server, but I cannot spin up a new server. Its by a private cloud provider, they don’t provide panel to reset or something.
I have done a switch from conventional to Docker myself and @rbn.dev is quite right about mariadb and redis artifacts causing mischief. That being said, using apt to remove redis-server and mariadb-server as well as ngtinx before attempting the Docker install is a good idea if spinning up a new server is not an option.
