Error while Computing

(moderation:
I have setup running Boinc on my Raspberry PI 5, Unbuntu 20.10, (Boinc manager says Pre-release), I did have to get some help from Youtube to get it working. Its finished quite a few units but every one has failed, I have just noticed this logging into Einstein website,
I clicked on a task and the info below, the units took approx 2.5hours each, is the error in the text below saying "Symbol lookup error"?
Can anyone help please why every single unit from the PI has failed.

Typically the "undefined symbol" error is the result of a missing library (or mismatched version). The "ldd" utility allows you to examine an executable file to verify that all internal (relocatable) symbols can actually be found. The syntax is "ldd -r <executable file name>" where the -r option looks for data and function names. You do not need to run this as root. The good news is this will show any missing symbols; the bad news is it can't tell you what library is required to supply those symbols (How could ldd know?... ) . The usual libraries are: libpthread, libm, and libc. It could be more complicated, but this is the first, and easy, thing to check.
A real Pi 5 user may (soon) chime in with more specifics. I'm just Linux AMD/Nvidia.
Thanks for your replies

Thanks for your replies Gents, I couldnt get it to work so decided to try the Raspberry OS, the Boinc software installed very easily and now working and getting credit for units,
So I couldn't fix it in Ubuntu but it works perfectly OK in the Raspberry OS on the PI 5
The reason you couldn't get

The reason you couldn't get Ubuntu to work is that you were using too old a version that does not recognize the device.
