I've one fine machine running i386 flavor of Debian 9.13 .
I've wish to install 64 bit flavor on a second machine.
debian-10.8.0-amd64-netinst.iso was successfully downloaded & saved.
It was copied to a USB flash drive and installation attempted.
Only did minimal install as I could not connect to internet.
To eliminate possibility that second was itself defective I attempted a
multi-boot install to the first machine [Dell Latitude E6410].
Essentially same result :{
Connection to internet is via a T-Mobile Alcatel Linkzone Hotspot.
The WiFi connectivity programmatically disabled (i.e. it is effectively
just a modem).
It is detected by lsusb as:
Bus 002 Device 008: ID 1bbb:0195 T & A Mobile Phones
No non-free driver is needed as none are on the working system.
I attempted to configure the ethernet device with the numeric URL the
working machine uses when configuring it. The installer was happy until
it tried to connect to a chosen mirror. I tried 3 in the United States
and 1 in Canada. None worked.
As I can boot a working Debian on that machine, all installer logs for
the failed install are conveniently available.
Also I didn't find anything in
https://www.debian.org/releases/stable/amd64/ telling details of how to
set up a "ethernet" device.
What do I do now?
