installation failure when trying rc5 or final iso on lenovo x220 with samsung ssd as target

[kai....@gmail.com]

greetings,

i copied the current iso (tried it.both with rc5 and with today final official iso) to a 32gb usb stick
and made my lenovo x220 boot from it. all went well until i choosed to habe the newly installed
samsung 512gb ssd as target (it was listed in the graphic menu of the available targets).

the system kind of halted for a second or two and then throwed an
anaconda 25.20.9-12 exception report
Trace back (most recent file first):

File "/usr/python3.5/site-packages/blivet/devicetree.py", line 184, in _remove_device raise ValeError("Device %s not in tree" % dev.name)e
...

The exact same line raised already an error when trying to install rc5 on two other lenovo laptops (t430 and
l560) with several different usb drives as targets some days ago.

So at this point, i am a bit without clue what else to try, to get qubes installed and i am wondering
a bit what causes all the other installations to work for all other users?

all the best
Kai

may be it is worth to add that the very same hardware combination worked flawlessly when trying to install qubes 3.2 instead (just tried again to make sure)

btw, i also apreciated that version 3.2 installer supports so many different langauges apart from english.

hope that helps

Look at the custom install Qubes page.

Go in the tty3 and format your drive from there according to instructions. Then go back to GUI and try to install.
