Good day!

I am completely at loss: suddenly sudo started to complain about no tty 
being present. The deal is with uart and display tty(/dev/tty1 and 
/dev/console agettys). Is there a way to troubleshoot what is actually 
missing for sudo to recognize tty being present? Executing tty command 
in the same terminal returns proper /dev/tty1 and /dev/console 
accordingly. Custom linux distro with latest major kernel version.

Looking forward to any assistance.

Semion Nadezhdin.
