install npm (node have been installed, npm missed)

Question

Ubuntu version is 18.04.1 LTS

I need to upgrade node version. So following some forum recommendations I've uninstalled npm and node:

sudo npm uninstall npm -g
sudo apt-get purge --auto-remove nodejs

install latest version of node:

curl -sL https://rpm.nodesource.com/setup_11.x | bash -
sudo apt update
sudo apt install nodejs

checking results:

> node --version
v11.6.0
> npm -v
bash: /usr/local/bin/npm: No such file or directory

trying to fix:

sudo apt-get install npm

Question

Is any ideas, how to fix broken packages and install npm of latest version?

More details:

following answer.

dpkg --get-selections | grep hold

prints nothing.

> sudo aptitude -f install node
env: ‘aptitude’: No such file or directory

different answers have not helped me.

@karel So... which package is broken? node, npm or different one? — Serhii, Jan 10 '19 at 22:05
To be honest if you install the node snap package you get all this: 1. npm is installed along with it 2. the latest version 3. your choice of all or any of the multiple versions of the node snap package 4. snap packages are standalone, so there are no possible problems due to broken packages - How can I install npm on 17.10? — karel, Jan 10 '19 at 22:10
@karel. I have no idea, how the links can help me fix my issue. following this links (with incomplete answers) issues and questions increases only. — Serhii, Jan 10 '19 at 22:20

I have not managed my issues with broken packages (it seems hard to detect ones, but hoping somebody knows answer). But I've managed issue with node and npm.

To install node i've used article how to manage nodes with nvm.

install nvm:

> curl https://raw.githubusercontent.com/creationix/nvm/master/install.sh | bash
> source ~/.bashrc # to reload env

check accessibe versions for install:

> nvm ls-remote # to find latest stable version
> nvm install v11.6.0 # install node

and now I've installed:

> node -v
v11.6.0
> npm -v
6.5.0-next.0

Npm can be updated following their instruction:

npm install npm@latest -g

Yes, Node Version Manager (nvm) is the final solution worked for me, reference https://www.digitalocean.com/community/tutorials/how-to-install-node-js-on-ubuntu-22-04#option-3-installing-node-using-the-node-version-manager — Happy, Sep 20 '22 at 05:09
