Sadly, after the install, there are no templates at all.
During the install I never saw this screen:
I am trying this on a new pc build on which 4.2 failed to install due to the “network configuration bug”. Is there anything obvious I can/should try?
Can you run the following command in a dom0 terminal to see if you can access the post-install menu?
sudo /usr/libexec/initial-setup/initial-setup-graphical
It’s a very frequent bug of Qubes OS installer: skipping the last installation screen/step. This bug was there in R4.2, R4.1 and probably before. I encountered it several times.
The solution that I know is to shred the disk and reinstall Qubes OS again, if you are installing it to an empty drive.
Perfect, this worked!
Now I’m trying to also get my usb wifi key to work (netgear nighthawk a7500) 
Thanks for the sanity check I ran in to the same issue
Are you sure that’s the only thing that is missed when this bug happens?
I mean I saw this workaround, but I am still not sure that it’s a good idea to run it and use OS further. Can it be, that something else should have been started by installer and was missed. Or not?
I have no idea, but I would guess that the post-install menu handles everything. If something important was missing, the system probably wouldn’t be usable.
No issues so far.
