Let me start by apologizing if it turns out I just really suck at searching. I couldn't find much on this problem, much less a solution. At a very basic level I generally understand what "Hash Sum Mismatch" means. I just don't really know what to do about it. When I try to download and install OpenSSH after a fresh 4.3.3 jailbreak using Redsnow I get an error in Cydia, "Hash Sum Mismatch". I'm not sure what I should do, if anything. There was a problem with the jailbreak the first time so I restored and did it again and everything else seems to be working fine. Any help would be greatly appreciated.
