When I try to load a program to radare2 debug mode, most of the time I get the following error:
$sudo r2 -d a.out
Hello world!= attach 2851 2851
Cannot open '/proc/2851/maps': No such file or directory
Hello world!asm.bits 64
Cannot open '/proc/2851/maps': No such file or directory
-- Now i'm like an evil engineer. MUAHAHAH

Radare2 works but doesn't load the program. Should I need to configure something else on the system?
This is on Ubuntu 18.04.1 LTS.
I think I had a similar issue and I got it solved by making sure that the target program has executable permissions set. Something like this in your case
chmod +x a.out
Hope that helps!
