Installing Node.js 10.x on Ubuntu Focal (20.04) before the official release

Installing Node.js 10.x on Ubuntu Focal (20.04) before the official release

Comments 0 Comment

Hi everyone,

Today, I’ll guide you through the steps of installing Node.js 10.x on Ubuntu Focal (20.04) which is stated to be officially released on April 23, 2020.

Right now, installing Node.js using the NodeSource Node.js official repositories do not work because they do not support unreleased versions of Ubuntu.

You may think of using a previous Ubuntu repository in order to install Node.js, but this will actually not work. This is because Ubuntu 20.04 renamed the Python 2 packages from python to python2.

Trying to install Node.js using the NodeSource repositories

The easiest way to normally install Node.js 10.x is by using the official NodeSource repository. For this, we follow their steps.

curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash

The problem is that because the OS hasn’t been officially released, we get the following issue:

NodeJS script failing on Ubuntu Focal 20.04

No problem. Let’s move to the manual installation method:

  1. Add the NodeSource package signing key:
    curl -sSL https://deb.nodesource.com/gpgkey/nodesource.gpg.key | sudo apt-key add -
  2. Set the version to node_10.x:
    VERSION=node_10.x
  3. Let’s set the distro to eoan, the current stable Ubuntu version:
    DISTRO="eoan"
  4. Now, we need to add the repository to our Linux installation:
    echo "deb https://deb.nodesource.com/$VERSION $DISTRO main" | sudo tee /etc/apt/sources.list.d/nodesource.list
    echo "deb-src https://deb.nodesource.com/$VERSION $DISTRO main" | sudo tee -a /etc/apt/sources.list.d/nodesource.list
  5. The commands should like this in the terminal:
    NodeJS Manual installation commands
  6. We can now run sudo apt update to update the repository information:
    NodeJS manual installation apt update
  7. We will now attempt to install the nodejs package by running sudo apt install nodejs:
    NodeJS installing nodejs fails

As you can see above, following the manual installation steps fails as well because there is no python-minimal package in Ubuntu 20.04. To solve this, we will manually download the Node.js Debian package and modify it to have it refer to python2-minimal instead of python-minimal.

Manually downloading, modifying and installing Node.js 10.x

  1. We will manually navigate to the repository to download the file here: https://deb.nodesource.com/node_10.x/pool/main/n/nodejs/
    NodeJS HTTP repo
  2. From there, just copy the desired Node.js package link to the clipboard. Then, use wget to download it on the terminal. I recommend downloading it to a clean directory since we will run some commands to extract and perform some modifications to it:
    Downloading the NodeJS debian package
  3. Once the download finishes, we need to extract the downloaded debian package with the ar utility:
    ar x nodejs_10.19.0-1nodesource1_amd64.deb
    extracting the NodeJS debian package
  4. We need to extract the control.tar.gz file:
    tar -xzf control.tar.gz
    Extracting control.tar.gz
  5. Using nano or your favorite text editor, we will edit the control file. Look for python-minimal:
    nano control
    Editing the control file
  6. Change python-minimal to python2-minimal:
    Renaming python-minimal to python2-minimal
  7. Save the file. On nano, press CTRL + O, then exit pressing CTRL + X.
  8. We now need to recreate the control.tar.gz tar package to include the modified control file. To do this, we will run the following command:
    tar -czf control.tar.gz control md5sums postinst pr einst prerm
    Recreating the control.tar.gz file
  9. Finally, we will replace the control.tar.gz in the debian package file. We will run the following command to do so:
    ar -r nodejs_10.19.0-1nodesource1_amd64.deb control.tar.gz
    Replacing the control.tar.gz in the NodeJS debian package
  10. We can now install the package with dpkg. We’ll run the following:
    sudo dpkg -i nodejs_10.19.0-1nodesource1_amd64.deb
    Installing the modified NodeJS debian package

After following the above steps, we should have Node.js installed on our operating system. We can confirm this by running node -v and npm -v:

Checking NodeJS and npm versions

And that’s it! We have successfully installed Node.js on our Ubuntu Focal installation.

GRC Remote
How to enable RPC in your Gridcoin Wallet?

How to enable RPC in your Gridcoin Wallet?

Comments 0 Comment

Hi everyone,

Today, I want to tell you how to enable Gridcoin’s RPC protocol to use apps like Gridcoin Remote on Android phones. This allows you to check stuff like your Gridcoin balance, magnitude, CPID, and more!

Here’s how you can enable it. There are 2 options:

Option 1: Gridcoin Remote Configuration Tool for Windows

GRC Remote

Download the Gridcoin Remote Configuration Tool for Windows available in Github. This tool will let you specify the IP Addresses allowed to connect, the Port Number, Username and Password, and it also has a tick box in case you decide to disable RPC access.

You can download this tool on GitHub: https://github.com/moisesmcardona/GridcoinRemoteConfigurationTool/releases

Option 2: Edit gridcoinresearch.conf manually

To edit the gridcoinresearch.conf manually you’ll need to locate that file. It is usually stored in “C:\Users\Your Username\AppData\Roaming\GridcoinResearch”, where “Your Username” is your Windows account folder.
Once you find the gridcoinresearch.conf file, open it in your favorite text editor.

You’ll need to add or edit the following lines:

server=1
rpcallowip=
rpcport=
rpcuser=yourusername
rpcpassword=yourpassword

Change the values after the = to the values you’d like to use. An example of how the lines should look are below:

server=1
rpcallowip=192.168.1.*
rpcport=9332
rpcuser=myusername
rpcpassword=mypassword

Now, save your config file and restart the Gridcoin Wallet. Once it loads, you can connect to it by using the Gridcoin Remote app.

Please be careful with RPC. Not only will Gridcoin Remote work, but anyone with additional knowledge may control your wallet. This is why it’s recommended to only allow IP Addresses you trust, and be careful if you expose the port to the public in your router’s port forwarding page. It’s better if you use an internal VPN. DD-WRT provides such simple VPN that you can connect to and use Gridcoin’s RPC functionality while away. This way, you don’t need to expose the port to the public.

Hope these steps were useful!

Hi everyone,

Today, I’d like to show you how easy is it to cook Chicken Drumsticks:

First, we defrost them and place them in the Air Fryer:

Chicken Drumsticks - 1

We then will give it 10 minutes. When it finishes, we will turn them and give them 10 minutes. We will keep doing this process until the Chicken Thights looks like this (Note that I did a quick cut to allow them to cook faster):

Chicken Drumsticks - 2

We will cook Frnech Fries if we want to, by giving them 5 minutes and turning them. Then we give them another 5 minutes:

Chicken Drumsticks - 3

Dinner is served:

Chicken Drumsticks - 4

Pork Chops - Air Fryer - 1

Hi everyone,

In this post, I’ll show you how easy it is to prepare Pork Chops 😂

The first step is to defrost them:

Pork Chops - Air Fryer - 2

The second step is to season them:

Pork Chops - Air Fryer - 3

The third step is to put them in the Air Cooker:

Pork Chops - Air Fryer - 4

We will give them 10 minutes at 400 degrees. Once it finishes, we will turn them and give them another 10 minutes:

Pork Chops - Air Fryer - 5

Once it’s finished, they are ready to be eaten:

Pork Chops - Air Fryer - 6

Bonus:

Preparing fries: We simply put them in the air cooker and we give them 5 minutes at 400 degrees. Then, we turn them and give them another 5 minutes but we lower the temperature, so they will not get burned. This way, we eat more healthy since we are not frying them:

Hi everyone,

In this post, I’ll show you how fast an easy it is to prepare food on a Convectional Oven.

Today, I’ll use it to heat some Chicken Fries that are sold in ALDI supermarkets.

Preparation:

The bag says that the serving size should be 7 chicken fries pieces, so we will put 7 pieces into the grill of the oven:

Cooking Chicken Fries on a Convection Oven - 1

Now, we will press the Chicken Pieces button, reducing the amount of time from 20 to 15 minutes, as it will burn with the original time. We will still need to check the Chicken Fries to make sure they do not get toasted too much:

Cooking Chicken Fries on a Convection Oven - 2

When we see that they are getting more baked, we can turn them so the other sides can get baked as well. Once we see them they are getting darker in color, we can remove them as they are ready to be eaten, but be careful, as they will be hot.

The way they should look is like follows:

Now they’re ready to be eaten!
