Describe the problem

https://github.com/colouring-cities/ccrp-technical-manual/wiki/Setting-up-a-local-development-environment was tested with Ubuntu 20.04 LTS

Ubuntu 20.04 LTS in weeks - see https://endoflife.software/operating-systems/linux/ubuntu

https://github.com/colouring-cities/ccrp-technical-manual/wiki/Setting-up-a-local-development-environment was tested with Ubuntu 24 - and reportedly it fails

Valuable feedback we received:

When installing a local development environment I encountered the following:

1. Installing PostgreSQL: These commands don't work

sudo sh -c 'echo "deb[ http://apt.postgresql.org/pub/repos/apt](http://apt.postgresql.org/pub/repos/apt) $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/pgdg.list'

sudo wget --quiet -O -[ https://www.postgresql.org/media/keys/ACCC4CF8.asc](https://www.postgresql.org/media/keys/ACCC4CF8.asc) | sudo apt-key add -

I used these ones:

apt install postgresql

sudo apt install -y postgresql-common
sudo /usr/share/postgresql-common/pgdg/apt.postgresql.org.sh

Also the version of postgresql is a bit dated, should we upgrade to the latest version (i.e. 16 or 17?

Other errors:

Configure postgres to listen on network connection.

$ sudo sed -i "s/#\?listen_address.*/listen_addresses '*'/" /etc/postgresql/12/main/postgresql.conf

sed: can't read /etc/postgresql/12/main/postgresql.conf: No such file or directory

$ echo "host all all all md5" | sudo tee --append /etc/postgresql/12/main/pg_hba.conf > /dev/nulltee: /etc/postgresql/12/main/pg_hba.conf: No such file or directory

2. Configuring Node.js: The code below generates an error

export NODEJS_HOME=/usr/local/lib/node/node-v16.13.2/bin/
export PATH=$NODEJS_HOME:$PATH
sudo env "PATH=$PATH" npm install -g npm@latest

Error:

npm ERR! code EBADENGINE

npm ERR! engine Unsupported engine

npm ERR! engine Not compatible with your version of node/npm: npm@11.1.0

npm ERR! notsup Not compatible with your version of node/npm: npm@11.1.0

npm ERR! notsup Required: {"node":"^20.17.0 || >=22.9.0"}

I have not managed to proceed beyond configuration of Node JS.
