Ubuntu - Error with flashplugin (x64)

I got this error when I using LDAP Client with Flash:

• Error with: Package 'adobe-flashplugin' is virtual

And I thinks just use this command to fix it:

• sudo add-apt-repository ppa:sevenmachines/flash && sudo apt-get update && sudo apt-get install flashplugin64-installer
• sudo apt-get install chromium-browser flashplugin-installer
