How to Install Blender 3.5 in Ubuntu

Option 1: Install Blender as Snap

For Ubuntu 20.04 and higher, it’s super easy to install the latest Blender package through the official Snap package.

Simply open Ubuntu Software, search for ‘Blender’ and click install it.

I’m not sure if Ubuntu software in 18.04 has added support for Snap, but user can just press Ctrl+Alt+T on keyboard to open terminal and run command to install the daemon & Blender as snap:

sudo apt install snapd && sudo snap install blender --classic

Option 2: Install Blender via the Linux tarball

Some users do not like the snap package that runs in sandbox. For choice, Blender website offers the portable Linux tarball:

Download Blender

And here’s a step by step guide shows how to create app shortcut for the portable package.

Blender is also available to install as Flatpak package. For those prefer the classic .deb package, there’s a third-party PPA, though not updated at the moment of writing.

Install & Try out Ubuntu’s New Fonts in Ubuntu 22.04 | 20.04

Posted on by Kernel

The Ubuntu design team is working on new Ubuntu fonts and proposes to use as default in the upcoming Ubuntu 23.04.

For testing purpose, the team posted the .deb packages for the new fonts in this thread. User can try it out by installing in all current Ubuntu releases and report any issue in this page.

I’ve tried out the new fonts in Ubuntu 22.04 LTS. The text in system menu and application window becomes a bit thin and compact than before.

And, the document text in text editor looks enlarged, that I even doubted if the font size was changed mistakenly.

How to Install the New Fonts

First, press Ctrl+Alt+T on keyboard to open a terminal window. When it opens, run single command to download the 2 font packages:

wget https://launchpad.net/ubuntu/+source/fonts-ubuntu/0.862-0ubuntu2/+build/25677616/+files/fonts-ubuntu_0.862-0ubuntu2_all.deb https://launchpad.net/ubuntu/+source/fonts-ubuntu/0.862-0ubuntu2/+build/25677616/+files/fonts-ubuntu-console_0.862-0ubuntu2_all.deb

Install wget via sudo apt install wget if it says command not found.

After downloaded the packages, use command to install them:

sudo dpkg -i fonts-ubuntu-console_0.862-0ubuntu2_all.deb fonts-ubuntu_0.862-0ubuntu2_all.deb

You can then remove the 2 packages in user home folder. And restart computer to apply changes after installation.

How to Restore original fonts

The stock fonts package version varies on different Ubuntu editions, so I would recommend to first install Synaptic package manager in Ubuntu Software.

Then, open “Synaptic” and do:

  1. Search and highlight “fonts-ubuntu” package.
  2. Go to menu “Package -> Force Version”.
  3. Select the old stock version from pop-up dialog, then click “Force Version” button.
  4. Finally, click “Apply”.
  5. Also, do the previous steps one by one for “fonts-ubuntu-console” package.

Also, restart computer to apply changes and done!

How To Clear Apt Cache In Ubuntu, Debian, And Linux Mint

In this tutorial, we will show you the easy way to clear Apt Cache in Ubuntu, Debian, and Linux Mint. apt (Advanced Package Tool) is a command-line package manager used in Debian-based Linux distributions?  It is used to manage software packages on a Linux operating system. apt is used to install, update, upgrade, and remove packages from the system with a simple command-line interface.

Generally, packages are stored in the Cache folder being installed on the system. Most of the packages are stored in the Cache directory which is located at ‘/var/cache/apt/archives’. Apt stored packages in the cache for future usage as the other software might need to use it.

But as the system gets older, a lot of packages get stored in the Cache occupying the space. So, it’s better to practice clearing Apt Cache and clearing the storage.

How To Clear Apt Cache In Ubuntu, Debian, And Linux Mint

There are multiple ways to clear Apt Cache in Ubuntu, Debian, and Linux Mint-based operating systems.

Apt Autoclean Command

Run the following command to remove the packages from Cache.

sudo apt autoclean

Apt Clean Command

Run the following command to delete the apt-cache.

sudo apt clean

 

If you run ‘apt clean‘ with a parameter called ‘–dry-run‘, then it will show you the directories from which packages will be deleted, and will not actually delete the packages.

 sudo apt clean --dry-run

sudo apt install build-essential git cmake libhidapi-dev

2. Then, clone the source by running the git command in terminal, and then navigate to the source folder:

git clone https://github.com/Sapd/HeadsetControl && cd HeadsetControl

3. Create ‘build’ sub-folder, navigate to that sub-folder and start building it:

mkdir build && cd build && cmake ../

4. Finally, run make and then make install to build and install the tool:

make -j4
sudo make install

Once successfully installed, it will output that ‘/usr/local/bin/headsetcontrol‘ and ‘/usr/local/lib/udev/rules.d/70-headsets.rules‘ installed.

How to Install the Extension for graphical UI

For Ubuntu 22.04 and higher, first search for and install “Extension Manager” from Ubuntu Software.

Uninstall:

To remove the extension, either go to the link page above and use ON/OFF switch, or use “Extension Manager” or Gnome Extensions tool.
