modprobe: ERROR: could not insert 'tty0tty': Device or resource busy

[zoltanmaric]

I can't run the emulator under 4.15.0-32-generic in Ubuntu 18.04. Here's what I tried:

cd modules
make
sudo cp tty0tty.ko /lib/modules/$(uname -r)/kernel/drivers/misc/
sudo depmod
sudo modprobe tty0tty # this fails with "modprobe: ERROR: could not insert 'tty0tty': Device or resource busy"

and there are no tnt* devices under /dev/.

This used to work under 4.15.0-29-generic, but not under 4.15.0-30-generic or 4.15.0-32-generic.

Could you please help me with this?

PEBCAK

Sorry, I cloned both this repository and lcgamboa/tty0tty, and I was attempting to perform the steps in the other one instead of this one. The steps above work just fine with 4.15.0-32-generic. I'm closing the issue.
