I've just reattached to this project after an absence, and my first new WU completed and validated normally, but the next four errored out with 0 run time, like this:
Task 2348287
Stderr output
<core_client_version>7.0.14</core_client_version>

I'm using Ubuntu 12.04 Beta 1 and BOINC 7.0.14... Any ideas?

Seems that you have to install the ia32-libs package. What I don't understand is how can it be that you computed OK the first WU and not the others. Wraper and Worker are the same.
/ Ah, yes, I had forgotten to reinstall the 32-bit libraries. I am doing so now.
Yes, it's very strange that the first WU worked. It's possible that something changed on my system during a Distribution update, due to it being a beta release of the OS. Perhaps it started with the libraries installed and they were removed by Update Manager. I'm not sure.
I'll try more WUs after these libraries download. :) Thanks.
/ Completed and validated. :)
