Just as the title says I getting an error after installing Ubuntu 10.10 64bit on a new machine. After doing updates and installing BOINC I was getting an error of "Recent Lost Result blah blah blah" and "Application version has unsupported platform i686". I found that a libs package was no longer included in the 10.10 build. To correct this error run the following commands from terminal.

sudo apt-get update
sudo apt-get install ia32-libs

I thought about putting this in the linux help thread but it relates only to Ubuntu at this time.
