Yesterday I installed a program to run windows games. The installation through the terminal spat out ten different types of “Error reading the jupitos bus” type messages that I simply could not parse, but they sounded grim and serious.

But it ran just fine afterwards so those messages couldn’t have been that important?

the resulting error messages normally at least give you something to search for

lp0 on fire

And:

#include <errno.h>
#include <stdio.h>

int main (void) {
    errno=ENOANO;
    perror("");
    return 0;
}

Yields:

$ ./a.out 
No anode
