.confluent/home/etc/kafka/zookeeper.properties: no such file or directory

I am trying to get started with Confluent CLI for local development on my Ubuntu 21.04.
After the installation like it is suggested

curl -sL --http1.1 https://cnfl.io/cli | sh -s -- v1.36.0

I cannot simply do local services start:

% confluent local services start

The local commands are intended for a single-node development environment only,
NOT for production usage. https://docs.confluent.io/current/cli/index.html

Using CONFLUENT_CURRENT: /home/serge/.confluent/current/confluent.310995
Error: open /home/serge/.confluent/home/etc/kafka/zookeeper.properties: no such file or directory

I added the following to my ZSHRC but it did not help

# Confluent local
export PATH="/home/serge/bin:$PATH"
export CONFLUENT_CURRENT=~/.confluent/current
export CONFLUENT_HOME=~/.confluent/home

What else can I do in this case?

Any help is very much appreciated.
