I am running Ubuntu 18.04. I wanted to install node and npm on my machine. The apt repository version of node is 8.x, whereas I wanted to have version 12.x (Current LTS version).

I followed the guide here: https://www.digitalocean.com/community/tutorials/how-to-install-node-js-on-ubuntu-18-04

As per the guide, I downloaded curl -sL https://deb.nodesource.com/setup_12.x -o nodesource_setup.sh

and then ran it with sudo -E ./nodesource_setup.sh

However, my machine fails to run sudo apt update with the following (full) output:

maxim@fujitsu:~/scripts$ sudo apt update
Hit:1 http://gb.archive.ubuntu.com/ubuntu bionic InRelease

This answer suggests that one should use apt update instead of apt-get update. None the less, I am running apt update.

This answers suggests to answer "Y" to the prompt.

This github issue, from the Docker community, makes it clear that doing so is a bad idea.

However, this answer, suggests that sometimes repositories change the names of package sources.

So my question is, is it OK to answer Y here? I don't want to just blindly accept whatever error the package manager throws at me.


If you don't answer Y to the question you never will get apt-get (or apt) working.

It seems reasonable that a security repository sets its 'Suite' value to 'bionic-security'. Why it was bionic-updates I can't tell, but it probably was an error.

As for apt-get contra apt, apt was introduced in Ubuntu 16.04 as a new interface to the package system - se here: https://itsfoss.com/apt-vs-apt-get-difference/

To fix the "changed its 'Suite' value" issue run the following commands:

sudo apt clean
sudo apt autoclean
sudo apt update && sudo apt upgrade
