Wireshark source code and installation packages are available from https://www.wireshark.org/download.html.
Most Linux and Unix vendors supply their own Wireshark packages. You can usually install or upgrade Wireshark using the package management system specific to that platform. A list of third-party packages can be found on the download page on the Wireshark web site.
Wireshark and TShark look in several different locations for preference files, plugins, SNMP MIBS, and RADIUS dictionaries. These locations vary from platform to platform. You can use About→Folders to find the default locations on your system.
