A great article from Mat Newman, where he explains the installation steps for the IBM Connections plug-ins for IBM Notes 9:

A quick one to share today – how to get the IBM Connections Activities, Status updates and enhanced Business Card Plug-ins installed easily in IBM Notes 9:
Modify your access to /opt/ibm/notes
I found this was necessary because one cannot modify the content of /opt/ibm/notes using the installer from within the Notes client, and one cannot execute Notes as root, so:

• Open a terminal
• sudo nautilus
• Navigate to the /opt/ibm folder
• Right-Click Notes
• Choose properties
• Go to the Permissions tab,
• Change “others” to have “Create and Delete” rights.

Once you’re finished, you can modify the access back to the default using the same procedure.

Download and extract the Connections Plug-ins in IBM Notes 9

Download the Installer from the IBM Connections plug-in download available from greenhouse:

Once downloaded:

• Open the file in Archive Manager,
• Extract ConnectionsAddonInstaller.zip
• From within ConnectionsAddonInstaller.zip, locate the file “updateSite.zip” and drag that to your required install location.

Now you’re ready to install.

From within IBM Notes 9:

• File -> Application -> Install,
• “Search for New Features to install”,
• “Add Zip/Jar Location…”,
• Navigate to the updateSite.zip file extracted earlier.
• Next, Next, Accept, Install, etc, etc…

Restart Notes … VOILA! IBM Connections Activities, Status Updates and Enhanced Business Cards.
