Hello,
my machine is running leap 42.3 with all the latest updates installed but when
I start to install leap 15 from an ISO network CD, the process goes up to the
choice of the pre-installed OS version and found correctly the leap 42.3 BUT
immediatly after I got a pop-up error message :
"internal error please report a bug report with logs
run save_y2logs to get complete logs
d�tails storage:: Exception
Caller:
/mounts/mp_001/usr/share/Yast2/lib/y2storage/storage_class_wrapper.rb:260:in
'find_by_any_name'


When I don't want to run ruby I got an other popup window:
Calling the YAST module "Inst_update_partititon has failed'
and some other information sentences

any clue about the possible solution?

thanks
