BIOS update via DSU failed on M620

Dear PowerEdge list,

I am facing a problem when trying to perform a BIOS update on an 
Poweredge M620 system running Fedora C22 using dell system update 
(latest dsu from DELL repositories). I get the following error messages:

ls: cannot access /opt/dell/dup64/src/srvadmin-hapi: No such file or 
directory
Check /opt/dell/dup64/var/log/dell_rbu.dks.log for build error.

and finally

BIOS Update failed using Dell RBU method.
BIOS_VCKYF_LN_2.5.2 could not be installed


For a full log of the tried update, see below. Interestingly directories 
below /opt/dell/ do not exist. Any idea?

Best regards,
Michael
