No, this was stderr I noticed

Josip,

Thank you very much for your suggestions.  I think the amount of 
thrashing (detective work) done so far to problem-solve this seems to 
indicate that there is no clean LTS distribution upgrade for this VE.

I think I'll spare my cycles and instead migrate the data on the 8.04 
VE's to 10.04 VE's.  Thank you.
