... and get help when needed...
Unfortunately you are going to continue to be disappointed, if this is what you expect on internet forums where everyone that offers advice does so voluntarily. As Nick said, occasions do arise when nobody who might be prepared to help, has any idea what the problem might be. We do actually fare reasonably well here in this respect however. Take for example the Newbie Questions
section on the Linux Mint forums, as they have already been mentioned. At this moment in time, it has 4 unanswered topics on the first page, and another 4 on the second page. Compare that to our much smaller, quieter, Linux forum here. That's not to say a word against Linux Mint forums, where I am also a member; it just goes to show that topics going unanswered on internet forums where everyone who gives advice is a volunteer, is not unusual.
Supposing someone other than you had made your complaint here. Would you feel any responsibility towards them? Perhaps you would think that you should have made more effort to respond to their posts? If not, then please don't expect anyone here to feel responsible for your topic only receiving one response, either. We volunteers here do our best, but "real" life always comes first. I don't imagine you are any different in this respect.
Regarding your problem; issues with updates are often distro specific. As nobody had responded to your topic after a couple of days, I thought The-Toolman's response was perfectly adequate. Directing you to where you are likely to find the greatest number of Linux Mint users was good advice, in my opinion. I can't imagine what more you expect from volunteers who don't know the answer to your question.
