for back the old names for the interfaces: # nano /etc/default/grub edit the line GRUB_CMDLINE_LINUX="" to GRUB_CMDLINE_LINUX="net.ifnames=0 biosdevname=0"
Along about Debian 10, the standard first ethernet card interface for a
desktop machine, referred to as "eth0", was changed to "eno1". Just out
of idle curiosity, does anyone know why this was done? (It broke some
stuff on my machine.)
