How To Install Nodejs v18 on Ubuntu 22

I installed Ubuntu 22 on my new PC. When I installed nodejs, the default version installed was v12. So I want to upgrade it to version 18.

I tried few methods but only using nvm it was successful.

Different Methods To Install NodeJS on Ubuntu 22

Installing Nodejs with APT from default repositories- fail
Installing Nodejs with APT using a NodeSource PPA – fail
Installing Nodejs using Node Version Manager – success

Refer this tutorial from DigitalOcean

My Steps Installing Nodejs using Node Version Manager (nvm)

1) Firstly list the node version you want to install

nvm ls-remote

1	nvm ls-remote

ubuntu 22 - choose node version — ubuntu 22 – choose node version

2) Secondly, choose the version you want to install. I chose LTS v18 @ lts/hydrogen

nvm install lts/hydrogen

1	nvm install lts/hydrogen

ubuntu 22 - install node v 18 — ubuntu 22 – install node v 18

3) Check if you have installed the right version.

node -v

node -v

If You Got Checksum Error

At first, I had the checksum error, when I checked on the internet it was due to curl installed using SNAP (which I did). I have to re-install my curl using APT and remove the snap path from the path environment.

Curl still point to snap/bin.

curl

curl

echo $PATH

1	echo $PATH

ubuntu 22 - installing node problem due to curl installed by snap — ubuntu 22 – installing node problem due to curl installed by snap

Remove the snap/bin from the environment. Edit it using nano

sudo nano /etc/environment

1	sudo nano /etc/environment

Ubuntu 22.04 Apache – 403 Forbidden You don’t have permission to access this resource

I tried to access my internal website using http://localhost but I got error of:

403 Forbidden You don't have permission to access this resource

1	403 Forbidden You don't have permission to access this resource

I am able to access the website via 127.0.0.1

I have checked my files access and all is good.

Solution

ubuntu 22 apache2 localhost able to access now

1. Edit your default.conf add localhost as ServerAlias (sudo nano /etc/apache2/sites-enabled/default.conf)

<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port t>
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        #ServerName www.example.com

        ServerAdmin webmaster@localhost
        DocumentRoot /home/wanrazali/data/www       
        ServerAlias localhost
        ServerAlias 127.0.0.1

#rest of your configs

fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

127.0.0.1 localhost

# The following lines are desirable for IPv6 capable hosts

Install Signal Messaging Desktop on Ubuntu

Every knows that WhatsApp changes its End Users License Agreement (EULA) . Lots of people are worried about data privacy.

That is why I’m migrating to Signal Messaging. I installed Signal Desktop on Ubuntu but I faced small hiccup which I shared how to solve it.

Download Signal for desktop

Download it here: https://signal.org/en/download/#

and follow the given instructions.

Can get the signing key from the error messageInstall Signal official public software signing key

wget -O- https://updates.signal.org/desktop/apt/keys.asc |\
  sudo apt-key add -

1 2	wget -O- https://updates.signal.org/desktop/apt/keys.asc \|\ sudo apt-key add -

signal desktop install ubuntu - signing key — signal desktop install ubuntu – signing key

Add Signal repository to your list of repositories

echo "deb [arch=amd64] https://updates.signal.org/desktop/apt xenial main" |\
  sudo tee -a /etc/apt/sources.list.d/signal-xenial.list

1 2	echo "deb [arch=amd64] https://updates.signal.org/desktop/apt xenial main" \|\ sudo tee -a /etc/apt/sources.list.d/signal-xenial.list

Update Ubuntu package database and install signal

sudo apt update &amp;&amp; sudo apt install signal-desktop

1	sudo apt update && sudo apt install signal-desktop

signal desktop installation ubuntu - error during installation — signal desktop installation ubuntu – error during installation

If Installation error like me, add the signing key

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys [signing key]

//example
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 3B4FE6ACC0B21F32

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys [signing key]

//example

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 3B4FE6ACC0B21F32

Can get the signing key from the error message

signal desktop install on ubuntu getting the signing key

Then run the command

signal desktop installation ubuntu - add key — signal desktop installation ubuntu – add key

Reinstall again after adding the signing key

signal desktop installation ubuntu successful
