This page contains information on Flash, a proprietary format for delivering audio and video content, primarily over the Internet.
Flash is Non-Free Software
Adobe's Flash plugin cannot be included in Fedora because it is not free/libre and open source software. Adobe does release a version of the Flash plugin for Linux, and this can be used in Firefox, Konqueror and other popular Internet browsers. When Adobe releases a newer version of the Linux Flash plugin, it makes packages available for Fedora, but Fedora cannot include Adobe's plugin as long as it is unavailable as free and open source software.
Fedora 10, 11, 12 and Rawhide
This section contains information relevant specifically to installation of Flash on Fedora 10 or later releases.
Enabling Flash Plugin
Adobe offers several methods to install their 32-bit Flash 10 plugin. In general, the YUM version is preferred, since it allows the plugin to be updated automatically through Fedora's normal update mechanism. The YUM version simply installs the repository configuration files, after which you must install the Flash plugin separately.
To begin, refer to the Adobe site at http://get.adobe.com/flashplayer/. Select YUM for Linux to download, and confirm (or the .tar.gz version for the 64 bit alpha; see bottom).
This will download the adobe-release-i386-1.0-1.noarch.rpm file. Installation of the repository file adobe-linux-i386.repo to /etc/yum.repos.d/ can be performed by installing the .rpm file. Issue the following command within the directory where you have downloaded the repository rpm file.
su -c 'rpm -ivh adobe-release-i386-1.0-1.noarch.rpm'
The .rpm file also copies the adobe General Public Key (GPG key) to /etc/pki/rpm-gpg/RPM-GPG-KEY-adobe-linux but does not import it. To import the key, type:
su -c 'rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-adobe-linux'
The system is now ready to fetch rpm packages from adobe using yum. To verify this, take a look at the /etc/yum.repos.d/adobe-linux-i386.repo file that was just created. You should see something similar to the following:
[adobe-linux-i386] name=Adobe Systems Incorporated baseurl=http://linuxdownload.adobe.com/linux/i386/ enabled=1 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-adobe-linux
Notice that the file contains the URL where the packages are located, whether or not the repository should be enabled, whether rpm should check downloaded packages from adobe against the GPG key, and the location of the key itself.
On 32-bit Fedora
After completing the adobe repository configuration, run the following command to install the Flash plugin and ensure sound is enabled:
su -c 'yum install flash-plugin alsa-plugins-pulseaudio \ libcurl'
You may see messages indicating that
libcurl are already installed. This is not a problem. Note also that
nspluginwrapper is installed by default and will wrap the Flash plugin. If you have upgraded from a previous version of Fedora, make sure that
nspluginwrapper is installed and the latest version:
su -c 'yum install nspluginwrapper'
Next, you should check the plugin.
On 64-bit Fedora
32 bit wrapped version
These instructions will install a 32-bit plugin that will work with the 64-bit browser by being "wrapped" with nspluginwrapper.
After installing the repository configuration, run the following command to install the Flash plugin and ensure sound is enabled.
For Fedora 10:
su -c 'yum install flash-plugin nspluginwrapper.x86_64 \ nspluginwrapper.i386 alsa-plugins-pulseaudio.i386 \ libcurl.i386'
For Fedora 11:
su -c 'yum install flash-plugin nspluginwrapper.x86_64 \ nspluginwrapper.i586 alsa-plugins-pulseaudio.i586 \ libcurl.i586'
For Fedora 12:
su -c 'yum install flash-plugin nspluginwrapper.x86_64 \ nspluginwrapper.i686 alsa-plugins-pulseaudio.i686 \ libcurl.i686'
You may see a message indicating that
nspluginwrapper.x86_64 is already installed. This is not a problem.
Adobe also has a pre-release version of a 64-bit plugin. Until this is supported via yum, you will need to do the following:
- Download the .tar.gz version from Adobe here.
- Use "gtar -xzvf" to extract libflashplayer.so and put it in either in
- Restart Firefox.
- OR: An rpm for the 64bit alpha flash can be found here
Checking the plugin
After the installation, exit all copies of Firefox and start it again to enable the plugin. Then type the following text in the Firefox address bar:
A section similar to the following should appear:
This information tells you that the Adobe Flash plugin has been successfully installed.
In some cases,
nspluginwrapper produces SELinux AVC errors, some of which may prevent viewing Flash content. Changing the relevant SELinux boolean may resolve this problem, but eliminates a great deal of additional security when using
nspluginwrapper. To make the change, run the following command:
su -c 'setsebool -P allow_unconfined_nsplugin_transition=0'
libflashsupport package is no longer needed with Flash 10 and has been removed from Fedora 10. The Flash plugin now calls the appropriate ALSA functions directly, and in the default configuration ALSA delivers sound to PulseAudio.
