I get the following error at the early boot stage (soon after grub):

mount: mounts none on /dev/pts failed: Device or resource busy

I have asked the same question before here. But I was not able to solve the issue. Here is the output of the command grep -r "/dev/pts" * at /etc directory:

apparmor/severity.db:/dev/pts/* 8 9 0
apparmor.d/abstractions/consoles:  # program uses the /dev/pts/ interface, it actually has access to
