There will always be a lot of things to do after a fresh Ubuntu installation. Ubuntu 13.04 Raring Ringtail was scheduled to be released on April 25th. Now it’s still in beta and alpha stage, which means it’s not fully stable and may contain bugs and issues.
If you have already upgraded or installed Ubuntu 13.04, one important thing is to install Adobe Flash Player Plugin to enable flash in your browser.
There’re two ways to install Adobe Flash Player in Ubuntu, I would recommend using the second one if you’re running on a 64-bit system.
1. One is flashplugin-installer, which is available by default in Ubuntu Software Center. It automatically downloads and installs a copy of the plugin (The file downloaded is the tarball as provided on the Adobe website). For 64-bit Ubuntu, flashplugin-installer installs the 32-bit version of Flash and a related compatibility library which may be slower and less stable.
To install it, click the link below to launch Ubuntu Software Center and install.
2. The Canonical Partners repository contains a package called adobe-flashplugin. This package actually contains the non-free flashplugin itself (Note that this package is exactly the same file as can be installed by downloading from the Adobe website). For 64-bit system, I would recommend installing this package with the native 64-bit library.
To install adobe-flashplugin package, first enable the Canonical Partners repository by System Settings -> Software Sources -> Other Software tab and then check the repository below.
After adding the repository, update and install via 2 commands in terminal (Ctrl+Alt+T):
sudo apt-get update
sudo apt-get install adobe-flashplugin
