Install VirtualBox 7.1.x in Ubuntu 22.04/24.04 & Keep Updated

Last updated: September 12, 2024 — Leave a comment

This tutorial shows how to install Oracle VirtualBox in Ubuntu 22.04 and/or Ubuntu 24.04

VirtualBox is a popular free open-source tool for running different operating systems in virtual machines.

The tool is available in Ubuntu system repositories, but old. So, here’s the step by step how to install guide for latest version for beginners.

VirtualBox VM Manager

NOTE: VirtualBox so far only support x86_64 (amd64) CPU architecture type. Meaning for modern Intel & AMD CPUs.

Step 1: Download & Install the .deb package (Optional)

Oracle provides official .deb & .rpm packages for installing the software in Debian/Ubuntu & Fedora based systems.

User can select download the package by going to its website via the link below:

Download VirtualBox for Linux

Next, open the Downloads folder, then either double click on the package or use right-click menu “Open With Other Application” and select open the .deb package you just downloaded via Software Install (or App Center). Finally, click install button to install it.

NOTE: The installing process may fail sometimes due to old package in your system, in the case, just uninstall the old one (go to bottom for how) then try to re-install again.

Once installed, search for and launch it either from start menu or ‘Activities’ overview depends on your desktop environment.

Step 2: Add VirtualBox repository to keep it up-to-date

The .deb package you installed via ‘Step 1’ used to automatically add the repository. However, it does NO longer do the trick in recent versions.

So, here’s how to do it step by step via the new Ubuntu PPA policy.

1. Download & install the key

First, press Ctrl+Alt+T on keyboard to open up a terminal window.

When it opens, run command to make sure “/etc/apt/keyrings” directory exist:

sudo mkdir -p /etc/apt/keyrings

Then, run command to use wget to download key, dearmor it (so unreadable), and finally save it to that directory:

wget -q -O- https://www.virtualbox.org/download/oracle_vbox_2016.asc | sudo gpg --dearmor --yes --output /etc/apt/keyrings/oracle-virtualbox-2016.gpg

You can finally verify the key file, by running command:

cat /etc/apt/keyrings/oracle-virtualbox-2016.gpg

As the screenshot above shows you, it should outputs unreadable text.

2. Add VirtualBox repository

Before adding the source repository, first run command to get system code name:

cat /etc/os-release

The apt repository so far only support Debian Stable (& old stable), Ubuntu 22.04 & 20.04 LTS (focal, jammy). For all their based systems, use the code-name you got via this command.

Then, in terminal window, run command to create & edit a sources file:

sudo nano /etc/apt/sources.list.d/virtualbox.sources

Then in the terminal window, paste following lines:

Types: deb
URIs: https://download.virtualbox.org/virtualbox/debian
Suites: jammy
Components: contrib
Architectures: amd64
Signed-By: /etc/apt/keyrings/oracle-virtualbox-2016.gpg

Replace jammy (for 22.04, Mint 21.x) according to last command output, such as noble for 24.04/Mint 22, focal for 20.04/mint20.

When done, press either Ctrl+S or Ctrl+O and hit Enter to save file, then press Ctrl+X to exit.

Finally, verify the sources file by running command:

cat /etc/apt/sources.list.d/virtualbox.sources

It should outputs the content you just added into that file.

3. Update system package cache

After setup the source repository, run command to refresh your system package cache:

sudo apt update

The terminal output should print a line looks like:

“Hit:5 https://download.virtualbox.org/virtualbox/debian jammy InRelease”

4. Install or Update Virtualbox

If you skipped the “Step 1”, then you can install it (7.0.x series at the moment) by running command in terminal:

sudo apt install virtualbox-7.1

Finally, when a newer release is out, you’ll be able to update it through Software Updater (Update Manager) tool.

Uninstall

To remove VirtualBox, open terminal (Ctrl+Alt+T) window and run command:

sudo apt remove --autoremove virtualbox virtualbox-7.1

And, remove the source repository by simply deleting the key & sources files:

sudo rm /etc/apt/keyrings/oracle-virtualbox-2016.gpg /etc/apt/sources.list.d/virtualbox.sources

Also, run sudo apt update to refresh package cache.

Install & Setup Eye Candy rEFInd Boot Manager in Ubuntu 22.04/24.04

Last updated: May 4, 2024 — 1 Comment

This simple tutorial shows how to install and setup the rEFInd boot manager in your Ubuntu 22.04, and/or Ubuntu 24.04 computer.

Most Linux uses Grub2 as default boot-loader. Though, there’s a good alternative called rEFInd. It’s a free open-source boot manager for EFI/UEFI enabled computers, such as all Intel-based Macs and recent (most 2011 and later) PCs.

rEFInd with Matrix theme

Why rEFInd:

Compare to Grub2, rEFInd has a more eye candy boot interface, and a simple and easy to tweak config file.

No need to update something, it auto-scans for all boot-able systems on every boot, and displays you the OS menu entries from both local disk and removable device, such as USB drive and CD-R.

It’s more reliable at booting Windows with Secure Boot active. And, it provides handy options to shutdown, restart, and/or go to BIOS settings.

How to Install rEFInd:

The boot manager is quite easy to install in Debian, Ubuntu, and Linux Mint, since it’s available in system repositories.

1. First, launch terminal (press Ctrl+Alt+T on keyboard) and run command to verify if UEFI enabled on your machine:

ls /sys/firmware/efi

The command will list content of ‘/sys/firmware/efi‘. It will show you No such file or directory, if UEFI not enabled.

2. To install rEFInd from system repository, simply run command:

sudo apt install refind

The package in system repository may be old. To install the most recent version, use the official PPA maintained by software developer.

  • Run command to add the PPA: 
    sudo add-apt-repository ppa:rodsmith/refind
  • Update system package index: 
    sudo apt update
  • Finally, re-run apt install command to install the package: 
    sudo apt install refind

Remove duplicate icons in boot menu

After installing rEFInd, you can now restart your machine to see the new boot menu.

In menu, use left/right arrow keys to switch menu entries, hit Enter to boot, or press Tab (or F2) for more options.

For duplicate icons issue, simply use left/right arrow to select the icon (menu entry), and hit Delete key on keyboard, finally answer yes to remove that icon (menu entry). Though, deleting icon may NOT work when 3rd party theme is in use.

Install Themes

The menu interface is easy to tweak by editing the refind.conf file under “/boot/efi/EFI/refind/” directory. Every option has description text telling what does it do and how it works.

To be more straightforward, you can install third-party themes. And, here are some rEFInd themes in Github.

Most themes have how to install steps in Readme file, they are usually:

    • Open “Files”, and navigate to “Other Location -> Computer (or system, root, etc) -> boot -> efi -> EFI -> refind”. (Some Desktop may need to open File Manager as root first!)
    • Create “themes” folder in that directory if not exist.
    • Drag and drop the themes you downloaded (extract & re-name first) into that “themes” folder.

Finally, apply new theme by editing the refind.conf file under “/boot/efi/EFI/refind/“, and adding new line in the end (replace rEFInd-glassy accordingly):

include themes/rEFInd-glassy/theme.conf

NOTE: the theme folder name, rEFInd-glassy in the case, is unique according to the PATH to icons/imgs in ‘theme.conf’ file.

In case the boot menu screen resolution is low, you may also add (or uncomment by removing #) resolution max line to set the maximum available resolution, or use resolution 1024 768 for certain resolution (Note that not all resolutions are supported).

Uninstall:

To uninstall refind in Debian and Ubuntu based systems, open terminal and run command:

sudo apt remove --autoremove refind

Also remove the PPA (if added) by running command:

sudo add-apt-repository --remove ppa:rodsmith/refind

To get rid of the refind boot menu, you also need to remove all the related files:

sudo rm -r /boot/efi/EFI/refind

For more, see rEFInd in its official website.

How to Install iTunes in Ubuntu 22.04 | 24.04 (Step by Step)

Last updated: May 4, 2024 — 2 Comments

This is a step by step beginner’s guide shows how to install iTunes in Ubuntu 22.04 and Ubuntu 24.04 LTS.

Windows app is easy to install in Ubuntu & other Linux, thanks to Wine. However, it’s not so easy for beginners to install & setup Wine.

So, here I’m going to show how to install iTunes using Bottles (a wine runner) to make things as easy as possible.

NOTE that, iTunes running with wine does NOT detect iPhone, at least not for me. But, it’s OK for syncing music via iCloud! For just transferring music files, VLC is a good alternative.

iTunes 12.8.0.150 in Ubuntu 22.04 LTS

NOTE 1: This tutorial is tested and works in Ubuntu 22.04. Though, it should work in most other Linux!

NOTE 2: In this tutorial I installed iTunes 12.8.0.150! Newer versions either crash frequently or run into blank window.

Step 1: Install Bottles

As mentioned above, Bottles is a wine runner to make running Windows apps in Linux super easy. The only downside could be that it’s only available as Flatpak runs in sandbox.

Firstly, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to enable Flatpak support:

sudo apt install flatpak

Other Linux can follow official setup guide to enable Flatpak support.

Then, install Bottles as Flatpak by running command:

flatpak install https://dl.flathub.org/repo/appstream/com.usebottles.bottles.flatpakref

This command may have more than a thousand MB download due to run-time libraries. Don’t be worried about it. Installing Wine directly from its website will also has quite a few hundred MB files to download.

 

Step 2: Setup Permission for Bottles

Bottles is installed as Flatpak which runs in sandbox. By default, it has only file access to your user ‘Downloads‘ folder.

If you want to make apps, that are installed through Bottles, visible in start menu and/or dock, and access music files in other folders (such as ‘Music’ folder), then you have manually grant permissions.

Option 1: Use command to grant file access permission:

To allow Bottles to add apps into start menu, run command in terminal:

flatpak override com.usebottles.bottles --user --filesystem=xdg-data/applications

To allow Bottles (iTunes) to access your user Music folder, use command:

flatpak override com.usebottles.bottles --user --filesystem=xdg-music

Option 2: Use Flatseal, graphical tool.

Flatseal is a popular graphical tool to manage permissions for Flatpak applications.

First, open terminal (Ctrl+Alt+T) and run command to install Flatpseal:

flatpak install https://dl.flathub.org/repo/appstream/com.github.tchx84.Flatseal.flatpakref

After installed the tool, launch it. Choose “Bottles” from left, and click add “Filesystem -> Other files” permission for:

  • xdg-music
  • xdg-data/applications

Step 3: Download iTunes (exe)

Apple website only shows the download for the latest version of iTunes, which is NOT working good (even not work so far) with current version of Wine.

For the old versions, there’s a 3rd party website that provides a large list of downloads. All download URLs in that page are official (point to apple.com), the website only lists them out for you.

Download iTunes (old versions)

In my tests, iTunes 12.9.x is the most recent version that installs, which however CRASH quite often. The iTunes 12.8.0.150 is the last that’s working good.

NOTE: Wine and Bottles keep updating with new features and bug-fixes. So, newer iTunes versions might be working in future when you see this tutorial. Try for your self.

Step 4: Install iTunes

Now, search for and launch “Bottles” from start menu or ‘Activities’ overview depends on your desktop environment.

NOTE: first time installing a Flatpak app, need a log out and back in to make app icon visible in start menu. For choice, you may run flatpak run com.usebottles.bottles command to start it from terminal.

In the first launch, follow the wizard to run the initial setup.

When done, click either “Create New Bottle…” button or the top-left “+” icon to get started.
Then, in next window type a name (‘iTunes’ in the case), select “Application” as environment type, and click “Create”.

Next, it automatically generate configuration and config Wine for the new ‘Bottle’ you just created.

When done, click to open the ‘Details’ page for the new bottle you just created. Click on “Run Executable” button, then browse and choose the “iTunes64Setup.exe” file you downloaded in last step.

Note in the file chooser dialog, you may need to switch bottom filter to “All Files“, so to make the .exe file visible.

After that, the installer wizard for iTunes should start. Just follow to install it until done.

Step 5: Launch iTunes

To launch iTunes, either go to ‘Details’ page for the Bottle in Bottles, and click the triangle icon “▸”.

Or, click the 3 dots “⋮” icon right after it, and select “Add Desktop Entry” menu option (need to done Step 2 first).

After that, you can start iTunes from start menu, just like other apps installed from Ubuntu Software.

Uninstall

To remove iTunes only, simply launch ‘Bottles’ and go to Details page for iTunes. Then use the top-right corner “⋮” menu option to delete bottle.

To remove Bottles app, open terminal (Ctrl+Alt+T) and run command:

flatpak uninstall --delete-data com.usebottles.bottles

In command, skip --delete-data will keep the apps installed through Bottles

After removing Bottles, also run the command to remove useless run-times to free up disk space:

flatpak uninstall --unused

How to Easily Transfer Music from Ubuntu Linux to iPhone

Last updated: December 21, 2023 — 1 Comment

Got local music files in your Ubuntu PC/laptop? Here’s how to transfer them to your iPhone.

It’s NOT hard to install iTunes in Ubuntu using Wine in today’s Linux. However, iTunes running in wine does not detect my iPhone, at least in my case in 22.04.

If you just want to transfer music from PC to your iOS device, then you don’t have to struggle with iTunes in Linux. There are easy alternatives! And, VLC is a very popular one of them.

This tutorial is tested on iPhone with iOS 16.1.1, and Ubuntu 22.04 with default GNOME.

Transfer Music from PC to iOS via VLC

1. First, go to “App Store” and install the free open-source VLC media player in your iPhone or other iOS device.

VLC media player in App Store

2. Not sure if it required, but you may launch VLC in iOS for the first time to generate app folder.

3. Now, connect your iPhone or other iOS device into Ubuntu. Then, open “Files” and go to the mounted folder from left panel.

In my case, it’s a phone icon with text “Document on iphone”. In that folder, click VLC icon. Finally, drag’n’drop your music files into the VLC sub-folder.

When done, you can now open VLC in iphone/iOS, and find out the local music files under “Audio” bottom tab.

4. (Optional) If you want to use Apple Music or other app for music playback, then you can save songs to files.

First, navigate to “Songs” tab in VLC. Then, tap top right “circle with 3 dots” icon, and click “Select” to choose all the files.

Finally, use the bottom right icon to open menu to “Save to Files” for all selected music files.

Sadly, this feature does NOT enabled for Firefox Snap in my case for Ubuntu. User can choose to either install Firefox as .deb package, or manually enable Wayland support for the Snap pacakge.

Besides Wayland for Linux, Firefox 121.0 also adds Voice Control commands support on macOS systems, and prompts Windows users to install the Microsoft AV1 Video Extension to enable hardware decoding support.

Other features in Firefox 121.0 include:

  • Option to force links to always be underlined
  • New PDF viewer floating button to simplify deleting drawings, text, and images.
  • Option to disable the debugger; keyword on the current page.
  • Support :has() selector, the hanging and each-line keywords, balance keyword, lazy loading iframes.
  • tail call elimination support in WebAssembly language
  • Various security fixes.

How to Get Firefox 121.0

Most Linux that pre-installs Firefox, will build the latest package soon and publish into system repositories.
