Use APT when you need Ubuntu’s broad common-format bundle and can follow a terminal command; use App Center when you prefer a graphical installer and the package you need is actually listed for your release. They are not two separate codec systems. App Center is a graphical installation interface that can show snaps and Debian packages, while APT installs a named Debian package from your enabled repositories. For a regular Ubuntu Desktop installation, the usual package route is ubuntu-restricted-extras, although its contents extend beyond codecs and vary by Ubuntu release.
What App Center and APT are really comparing
App Center and APT perform the same general job—installing software—but expose different controls. App Center gives you a search-and-click workflow. APT gives you an explicit package name, repository transaction, and command-line output to review.

Ubuntu’s desktop documentation says App Center lists snaps by default. When you search for a Debian package, it can also show packages from Ubuntu’s official repositories; if the same application exists as both a snap and a deb, the snap is shown first. The distinction matters because a snap and a deb are different package formats with different confinement, update, and integration behavior. App Center is therefore an interface over listings from different sources, not a separate “codec repository.” See Ubuntu’s application-installation guide and its explanation of snap and deb packages.

That directness is useful for a metapackage such as ubuntu-restricted-extras, particularly when App Center does not expose the package in search.
First identify the media problem and your Ubuntu release
A codec bundle is not a guarantee that every audio or video file will play. Playback can also depend on the application, container format, hardware acceleration, DRM, Bluetooth profile, or a codec that is absent from your release’s repositories. Start with the actual symptom: note the file type or the player’s missing-codec message instead of installing several overlapping packages blindly.
Package contents and availability are release-specific. The package page for Ubuntu 24.04 LTS (Noble) describes the current archive entry; another release can add, remove, or change dependencies. If you are on a flavor such as Kubuntu, Xubuntu, or Lubuntu, check that flavor’s restricted-extras guidance rather than assuming the regular Ubuntu package is the right choice.
- Regular Ubuntu Desktop: the commonly documented bundle is
ubuntu-restricted-extras. - Ubuntu flavor: use the flavor-specific restricted-extras package or instructions when provided by that project.
- One unusual format: identify that format first; a broad metapackage may install unrelated extras without addressing the missing component.
- Bluetooth headset audio: check the release-specific installer notes, because the AAC package described for Ubuntu 26.04 targets a particular supported-headset scenario.
Installing through App Center
App Center is appropriate if you want a graphical flow and are comfortable checking the package listing before accepting it. The exact catalog shown depends on your Ubuntu release and enabled sources; official documentation does not establish that every codec-related package is searchable in App Center on every release.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minute- Open App Center from the Applications overview.
- Search for the exact package or a relevant term. If you are looking for the common Ubuntu bundle, try
ubuntu-restricted-extras. If no matching official listing appears, do not substitute an unrelated snap; use the APT method below or consult your flavor’s instructions. - Inspect the result’s package format and publisher/source. When both snap and deb listings exist, App Center normally places the snap first, so select the Debian package only when that is the package you intend to install.
- Select the package and choose Install. Authenticate with your account password when Ubuntu asks.
- Read the proposed package changes and any license dialog. A codec bundle can pull in fonts and archive utilities as well as media libraries; accept only if those additions fit your needs.
- Wait for the operation to finish, then close and reopen the media application that failed to play the file. Some applications load codec components only when they start.
If App Center shows a third-party Debian package rather than an Ubuntu repository package, pause before installing it. Ubuntu added third-party deb installation enhancements in 24.10, but its documentation warns that such packages may add repositories and have unrestricted access to the system. Ubuntu discourages third-party deb applications. Prefer an official Ubuntu repository package when it meets the requirement.
Installing the common bundle with APT
For regular Ubuntu, the Community Help guidance uses ubuntu-restricted-extras for common restricted media formats. The modern APT spelling is:
sudo apt update
sudo apt install ubuntu-restricted-extrasThe first command refreshes the local package index. The second requests the metapackage from your enabled repositories. Ubuntu Community Help also documents the equivalent older-style command sudo apt-get install ubuntu-restricted-extras; both commands use the same repository package system for this purpose.
- Open Terminal.
- Run
sudo apt updateand enter your password when prompted. A password is not displayed while you type. - Run
sudo apt install ubuntu-restricted-extras. - Read the transaction summary. APT lists new packages, additional disk space, and any removals before it changes the system. Enter
Yonly after checking that the proposal is expected. - Complete any interactive license prompt, including the Microsoft TrueType font license if it appears. The installation cannot finish until required prompts are answered.
- Restart the affected player and test the original file. If it still fails, record the format and error rather than repeatedly reinstalling the same metapackage.
If APT reports that it cannot locate the package, the package may not be in an enabled repository for your release, your package lists may be stale, or you may be using a flavor with different package guidance. Do not download a random installer to work around that message. Verify the release and repository configuration, then check the package information for your release.
What ubuntu-restricted-extras installs
On Ubuntu 24.04 LTS, the official package archive describes ubuntu-restricted-extras as a metapackage for commonly used media codecs and fonts. It depends on ubuntu-restricted-addons and recommends FFmpeg’s extra codecs through libavcodec-extra, Microsoft TrueType fonts, and the non-free unrar utility. The archive entry is in Ubuntu’s multiverse component. See the Ubuntu 24.04 package details.
| Component or behavior | What the Ubuntu 24.04 package metadata says | What that means for you |
|---|---|---|
| Media support | The metapackage is intended for commonly used restricted media codecs. | It is a broad starting point, not a promise that every codec, container, or protected stream will work. |
| Dependency | It depends on ubuntu-restricted-addons. |
Installing the metapackage can bring in a set of related packages rather than one codec file. |
| FFmpeg extras | libavcodec-extra is recommended. |
APT may propose additional codec libraries beyond the base bundle. |
| Fonts | Microsoft TrueType fonts are recommended. | Expect font-related files even when your original goal was audio or video playback. |
| Archive support | unrar is recommended. |
The bundle can add archive-extraction support that is unrelated to codec playback. |
Because this is a metapackage, its dependency set can change between Ubuntu releases. Check the package page for your release before treating the 24.04 description as universal.
Ubuntu 26.04 and the installer’s optional media packages
Ubuntu 26.04 LTS release notes describe a release-specific change to the Ubuntu installer. Selecting Install third-party software for graphics and Wi-Fi hardware and additional media formats installs optional packages that include a non-free AAC codec for supported Bluetooth headsets. This note concerns that installer option and headset use case; it does not mean that Ubuntu 24.04 or earlier releases install the same package, nor that one selection resolves every AAC or media-playback problem. Read the Ubuntu 26.04 LTS summary when installing that release.
If Ubuntu is already installed, the 26.04 installer checkbox is not a substitute for diagnosing a missing format. Use the package route appropriate to the installed release and the application reporting the failure.

How to choose the right method
Choose App Center when the listing is clear
Use App Center if you can find an official Ubuntu listing, can distinguish a deb from a snap, and want authentication and progress handled graphically. This is especially comfortable for a first installation or for users who do not want to interpret APT output.
Choose APT when the package name is known
APT is the better fit when instructions specify ubuntu-restricted-extras, when App Center search returns nothing useful, or when you need to see exactly which dependencies and recommendations will be installed. The command is reproducible and easier to document for support.
Do not choose on the assumption that one method has “better codecs”
For the same Ubuntu repository package, the graphical and terminal routes are different interfaces, not competing codec implementations. The meaningful choices are package name, package format, repository source, release, and the media format you are trying to play.

The package does not appear in App Center
App Center’s official documentation does not promise that every codec package is searchable in every release. Confirm your Ubuntu release, search the exact package name, and switch to APT if the official package is absent from the catalog. Do not install a similarly named third-party snap merely because it appears first.

Run sudo apt update again and check that the release and repositories are correct. If you use a flavor, consult its restricted-extras instructions. The package archive entry for Noble cannot establish availability or identical contents for every other release.
Best Value
The installer asks about fonts or a license
That is expected for a metapackage whose recommendations include Microsoft TrueType fonts. Read the terms and choose the response that matches your requirements; declining an optional component can leave the codec portion installed while omitting that recommendation.
The media file still will not play
Do not assume the bundle failed. Recheck the file’s format, the application’s error, and whether the content is protected or otherwise outside the package’s scope. The documented package is a common-format bundle, not a universal decoder for every file.
Bluetooth audio is still missing AAC
Apply the 26.04 qualification: Ubuntu’s release note refers to a non-free AAC codec for supported Bluetooth headsets when the installer’s optional third-party-software selection is used. That specific note does not establish the same behavior on earlier releases or for unrelated AAC playback.
Recommended Free Tools
A third-party deb offers a one-click fix
Check whether an Ubuntu repository package meets the need first. Ubuntu warns that third-party debs may add repositories and have unrestricted system access, and it discourages third-party deb applications. A convenient installer is not automatically a safer or more complete codec solution.
Security, licensing, and maintenance considerations
Restricted media support often combines software distributed under different licensing terms. The Ubuntu package metadata makes the bundle’s broader scope visible: fonts and unrar are recommendations alongside codec libraries. Review APT’s proposed changes and answer license prompts consciously rather than treating the command as a codec-only switch.
Official repository packages receive their metadata and updates through Ubuntu’s package-management system. App Center can also present third-party Debian packages, but those packages may alter repository configuration and run with broad system access. When two choices solve the same problem, the official Ubuntu repository package is the more conservative default.
A practical decision checklist
- Have you identified the Ubuntu release and, if applicable, the desktop flavor?
- Do you know the media format or the exact playback error?
- Is the package you found an Ubuntu repository deb, a snap, or a third-party deb?
- Does the package description include fonts, archive tools, or other additions you do not need?
- Have you read the proposed changes and any license prompt before confirming?
- If the problem involves Bluetooth AAC on Ubuntu 26.04, did you check the installer’s supported-headset qualification?
- After installation, did you restart the affected media application and retest the original file?
For most regular Ubuntu users seeking broad common-format support, the shortest reliable route is sudo apt update followed by sudo apt install ubuntu-restricted-extras, with the transaction and license prompts reviewed. App Center remains a valid graphical route when it presents the intended official package for your release; it is not a guarantee that every codec bundle will be listed or that selecting the first result installs the same package.
