Well, I'm not really sure that description represents the situation. I 
didn't just make up the issue of permissions. In fact, I don't know 
nearly enough about Linux to even conceive of a solution like that.
What I got was an error message, with the word "ERROR" in capital 
letters, and I looked it up on the net. I really can't see how that's an 
unreasonable course of action.

Following that, after I came across a suggestion that it was a 
permissions problem, I came here to this list to ask further, and I 
wasn't told right away "no, that's not a permissions issue, that's a 
different problem". I was told how to possibly modify permissions, and 
got kind of deep into it before someone finally said "hey, maybe it's 
not a permissions problem". So for a while I had a lot of support for 
the idea that it was a permissions problem.

In other words, faith doesn't enter into it. My understanding of Linux 
is only as good as the information I find in response to my queries.

I'm not sure how far I would get if I always assumed I was just doing 
things wrong every time I came across an error message. I've worked with 
computers long enough to know that an error is quite likely to actually 
be an error.
