I’m a user of the Windows 10 WSL feature, where I run the Ubuntu distribution and always install the latest versions. I like to keep my packages up to date. Unfortunately, the latest Ubuntu release, 21.04 was not installed correctly and whenever I tried to update the system packages, it would error out when setting up systemd.
The solution to this seem to be a quick one. Turns out, the file libsystemd-shared-247.so was there, in the /usr/lib/systemd folder:
It seems that we can get around this issue by copying that file to the previous folder (/usr/lib, so the following command should be used:
Ffmpeg allows these tools to work with a variety of formats. For example, on Exhale and Opus GUI, it allows a number of formats to be encoded into .opus and xHE-AAC formats. On rav1e and SVT-AV1 GUI, it is needed to allow non-raw files to be encoded directly to AV1.
Previously, my guides pointed to Zeranoe’s website, but it has been discontinued and those instructions are now obsolete. Here, I’ll guide you though the steps to download fresh ffmpeg builds for Gyan’s website.

Hi everyone,
In this post, I’ll guide you through the steps to download ffmpeg and use it in Exhale GUI. This is needed if you want to encode files in formats other than WAV.
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.
Let’s set the distro to eoan, the current stable Ubuntu version: DISTRO="eoan"
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
The commands should like this in the terminal:
We can now run sudo apt update to update the repository information:
We will now attempt to install the nodejs package by running sudo apt install nodejs:
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
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:
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
We need to extract the control.tar.gz file: tar -xzf control.tar.gz
Using nano or your favorite text editor, we will edit the control file. Look for python-minimal: nano control
Change python-minimal to python2-minimal:
Save the file. On nano, press CTRL + O, then exit pressing CTRL + X.
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
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
We can now install the package with dpkg. We’ll run the following: sudo dpkg -i nodejs_10.19.0-1nodesource1_amd64.deb
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:
And that’s it! We have successfully installed Node.js on our Ubuntu Focal installation.

Hi everyone,
In this post, I’ll show you how to download ffmpeg to use with SVT-AV1 GUI. FFmpeg is required to extract the video file to .y4m, encode the audio to Opus, and merge both files when the encode is finished.
2. Select the nightly build which is the first one shown in “Version”. Select the 64-bit Windows version if you have a 64-bit machine, and select “Static” in the Linking column. Then, click on “Download Build”:
Step 2
3. Click on the downloaded file:
Step 3
4. Go to the “ffmpeg” folder, and then to the “bin” folder. You should see “ffmpeg.exe” inside:
Step 4
5. Extract it and place it in the location where you have SVT-AV1 GUI:

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
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.
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.
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.
