APT is the more predictable way to install Ubuntu’s common restricted-format bundle: run sudo apt install ubuntu-restricted-extras on a regular Ubuntu installation, review the proposed packages and complete any license prompts. App Center is a graphical front end, not a separate codec system. It can show snap applications by default and Debian packages from Ubuntu’s repositories when you search for them, but Ubuntu’s documentation does not promise that every codec package appears in App Center for every release.
Choose App Center if you want to search and click through an authenticated graphical workflow. Choose APT when you know the package name and want an explicit, reproducible installation from your enabled repositories. Neither method guarantees support for every media format; the exact package contents depend on the Ubuntu release, edition and media format involved.
What App Center and APT actually do
App Center and APT are two interfaces to software installation. They are not two independent codec technologies. App Center provides a graphical catalog and installer. APT is the package-management command line used to request a named Debian package from configured Ubuntu repositories.
Ubuntu’s desktop documentation says App Center lists snaps by default. When you search for a Debian package, it can also list packages from the official Ubuntu repositories. If the same application exists as both a snap and a deb, the snap is shown first. That ordering matters because a reader searching for a media application can otherwise select a different package format from the one intended.
#1 Best Overall
APT does not search a visual catalog for you: the command identifies the package directly. For a standard Ubuntu installation, the commonly documented bundle is ubuntu-restricted-extras. Ubuntu Community Help gives the equivalent apt-get syntax, while current Ubuntu instructions commonly use apt:
sudo apt install ubuntu-restricted-extrasThe package must be available in an enabled repository for your release. Ubuntu’s 24.04 LTS package archive places it in the multiverse component, so a system with different repository settings may not be able to install it until those settings are corrected.
For the App Center’s package behavior and format ordering, see Ubuntu’s “Install an application” documentation and “Snap and deb packages”.

| Reader need | App Center | APT |
|---|---|---|
| Interaction | Search, select and click through a graphical interface; authenticate when prompted. | Run a terminal command and name the package explicitly. |
| Package formats | Snaps are listed by default. Debian packages from official Ubuntu repositories can also appear in search; when both formats exist, the snap is listed first. | Installs the named Debian package from configured APT repositories. |
| Selection control | Convenient, but inspect the format and publisher listing before installing. | Direct control over the package name, with terminal output showing the planned changes. |
| Best fit | Someone who prefers a graphical workflow and can find the required package in that release’s catalog. | Someone comfortable with a terminal or following an exact package instruction. |
| Main limitation | Official documentation does not establish that every codec package is searchable in App Center across all Ubuntu releases. | The package and its current contents depend on the release and enabled repositories. |
If your objective is the broad common-format bundle on regular Ubuntu, APT is usually the clearer route because the package name is known. App Center is still useful when you want to inspect a listing visually or avoid the terminal, provided the package is actually offered for your release.
Before installing: identify the real media problem
“A codec problem” can mean several different things: a video that has no picture, audio that is silent, a file that a player refuses to open, or a Bluetooth headset that cannot negotiate a particular format. Installing a broad bundle without identifying the symptom can add packages without fixing the relevant issue.
- Note the Ubuntu release and desktop flavor. Package availability and package contents are release-specific.
- Record the file or stream format that fails, such as the container and audio or video codec, rather than describing it only as “a movie that will not play.”
- Check whether the failure is limited to one application. A package installed for the operating system does not make every snap or application use identical codec components.
- Decide whether you need codecs only or also fonts and archive support.
ubuntu-restricted-extrasis a metapackage with additional recommendations, not a codec-only installer.
Ubuntu’s official package and release documentation does not claim that one bundle enables every codec or fixes every media file. Treat the package as a common-format starting point, then investigate the specific format if playback still fails.
Install the bundle through App Center
App Center can be appropriate when you want a graphical process. The exact catalog shown depends on your Ubuntu release and repository configuration, so use the package name as a search term but do not assume a result must exist.
Recommended Free Tools
- Open App Center from the Ubuntu application overview.
- Use the search field and enter
ubuntu-restricted-extras. If the package is not returned, do not substitute an unrelated media player or an unverified download; move to the APT method or investigate repository and release differences. - Inspect the result’s format and publisher information. App Center lists snaps by default and may list a Debian package from an official Ubuntu repository. If both are available for an application, the snap appears first.
- Open the package details and check the description before selecting Install. The bundle is described as providing commonly used media codecs and fonts on Ubuntu 24.04 LTS, with related recommendations.
- Authenticate with your account password when App Center requests it. Installation cannot complete without the required administrative authorization.
- Read the package-change summary and any license dialog. The bundle can recommend Microsoft TrueType fonts and the non-free
unrarutility, so a font-license prompt or additional package list is possible. - Wait for App Center to finish, then close and reopen the media application that was running when the installation began. Test the specific file or stream that originally failed.
The graphical workflow does not change the package’s release-specific contents. If App Center offers a snap or a third-party Debian package instead of the official repository package you intended, stop and verify the listing rather than assuming all entries provide the same system integration.
Install the bundle with APT
APT is preferable when you want the package name and source to be explicit. The command documented for a regular Ubuntu system is:
sudo apt install ubuntu-restricted-extras- Open Terminal.
- Enter the command exactly as shown and press Enter.
- When prompted, type your Ubuntu password. The password does not appear on screen while you type.
- Review APT’s transaction summary. Confirm that the package names, download size and additional changes are acceptable before agreeing.
- Read any interactive license prompt, particularly the one associated with Microsoft TrueType fonts, and select the option that matches your acceptance.
- Allow the installation to complete. If APT reports that the package cannot be located, check the Ubuntu release, enabled repositories and desktop flavor instead of repeatedly retrying the same command.
- Reopen the affected media application and test the format you identified earlier.
Ubuntu Community Help documents the older but equivalent form sudo apt-get install ubuntu-restricted-extras. The package name is the same; apt is the shorter command normally used in current Ubuntu guidance.
APT installs the Debian package from your configured repositories. It does not automatically turn an unrelated snap into a deb package, and it cannot install a package that is absent from the repositories enabled for your release.

Ubuntu’s 24.04 LTS archive describes ubuntu-restricted-extras as a metapackage for commonly used media codecs and fonts. A metapackage primarily collects other packages; its exact dependency and recommendation set can change between Ubuntu releases.
- It depends on
ubuntu-restricted-addons. - It recommends
libavcodec-extra, which supplies additional FFmpeg codecs. - It recommends Microsoft TrueType fonts.
- It recommends the non-free
unrarutility for handling RAR archives.
These entries explain why the install can be larger than a codec-only change. A recommendation is package metadata; whether recommended packages are installed also depends on your APT configuration. Review the transaction summary rather than assuming the bundle contains only the component you need.
The package archive for Ubuntu 24.04 LTS is the authoritative place to check the current description and dependency information for that release: Ubuntu Packages: ubuntu-restricted-extras for noble. Do not carry the 24.04 package list forward as a promise about another release.
Release, installer and edition differences
Ubuntu 24.04 LTS
The 24.04 LTS archive contains ubuntu-restricted-extras in the multiverse component and documents its dependency and recommendation set. That is the evidence for the package details above; a different release can publish a different set.
Rank #4
Ubuntu 24.10 and later App Center changes
Ubuntu’s documentation says App Center enhancements, including third-party Debian-package installation, were added in Ubuntu 24.10. A third-party deb is not equivalent to a package from the official Ubuntu repositories. Ubuntu warns that such packages may add repositories and have unrestricted access to the system, and discourages third-party deb applications. Prefer the official repository package when it meets the need.
Ubuntu 26.04 LTS installer option
Ubuntu 26.04 LTS release notes describe an optional installer choice labeled “Install third-party software for graphics and Wi-Fi hardware and additional media formats.” For that release, the selected media packages include a non-free AAC codec for supported Bluetooth headsets.
This is a release-specific installer feature and a specific Bluetooth-headset use case. It is not proof that the 26.04 option, ubuntu-restricted-extras, or App Center will enable every codec. It also should not be silently applied to Ubuntu 24.04 LTS or earlier releases. The wording and scope are documented in the Ubuntu 26.04 LTS summary.
Ubuntu flavors need their own package check
Ubuntu Community Help distinguishes the regular Ubuntu package route from flavor-specific restricted-extras packages. Kubuntu, Xubuntu and Lubuntu may publish a corresponding package for their desktop flavor. Before running a command copied from a regular-Ubuntu guide, check the flavor’s package guidance and the release you are actually running.
The App Center versus APT distinction remains the same on a flavor: App Center is the graphical interface, while APT installs a named package from configured repositories. What changes is the package name and the set of packages maintained for that flavor.

The Community Help guidance is available at RestrictedFormats.
Troubleshoot common installation and playback failures
App Center shows no result for the package
Do not treat an empty search as evidence that Ubuntu has no codec support. The official App Center documentation does not establish that every codec package is searchable in every release. Verify your release and flavor, then use APT with the exact package name if the package is available in your enabled repositories.
APT says it cannot locate ubuntu-restricted-extras
The package must exist for your release and be available through an enabled repository. Check that you are using a regular Ubuntu edition or the flavor-specific guidance, and verify repository configuration appropriate to that release. A command cannot succeed when the package is not published for the release or the required component is disabled.
The install completes but the file still will not play
The bundle is not a universal codec license. Recheck the exact audio or video format, the application producing the error and whether the problem is limited to a snap. The package’s documented purpose is common media codecs and fonts; it does not promise support for every proprietary or unusual format.
A Bluetooth headset still has no AAC audio on 26.04
The 26.04 release note ties its additional non-free AAC codec to supported Bluetooth headsets and to the installer’s optional third-party-software selection. If that option was not selected during installation, the release note does not say that the codec was installed automatically. This case is narrower than general video playback.
A license or extra-package prompt appears
That prompt is consistent with the metapackage’s recommendations. Read the text and decide whether you accept the relevant license. If you decline, the package transaction may omit that component while installing others; the resulting system may not have the same font or archive support.
A listing is marked as a third-party Debian package
Pause before installing. Ubuntu says third-party debs may add repositories and have unrestricted system access, and it discourages third-party deb applications. Use an official Ubuntu repository package when one is available, and install a third-party package only when you understand its publisher and system permissions.

- Want a graphical workflow? Try App Center, but verify the package format and publisher and remember that the codec package may not be listed.
- Know the package name? Use
sudo apt install ubuntu-restricted-extrasand review APT’s proposed changes. - Running a flavor? Check whether its restricted-extras package differs from regular Ubuntu.
- Need only a particular format? Identify that format first; the broad metapackage includes fonts and archive support as well as codecs.
- Installing Ubuntu 26.04? Consider the installer’s optional third-party-software selection if you specifically need AAC for a supported Bluetooth headset.
- Considering a third-party deb? Prefer official repositories because third-party packages can add repositories and have unrestricted access.
Bottom line
For regular Ubuntu, APT gives the clearest codec-install path because it names the package directly: sudo apt install ubuntu-restricted-extras. App Center is a convenient graphical alternative when the package is visible in your release’s catalog, but it is only an interface and may present snaps before deb packages. Check your release, flavor and failing media format, and remember that the restricted-extras metapackage includes related fonts and archive support rather than guaranteeing every codec.
