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 [0x00000000]>
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.
