All the sudden (last 4 or 5 days) I can't update any of my distros or software on 2 computers. I get a message to check my internet connection, that the package can't download. I have a gateway, intel b960 processor with 4.?ghz processing speed, 4gb ddr3 memory, and 500gb HDD, 64 bit wifi laptop with 3 distros and windows on. I have Mint qiana, ubuntu 14.04LTS, and open suse 13.1. Plus I have an old systemax (had xppro on) with 2.? ghz dualcore intel processor, 2gb memory, and 500gb hard drive, 32bit. I have 5 distros on it, mint qiana, ubuntu 14.04.1 LTS, Peach, Open suse 13.2, and zorin on it. It is a desktop machine that is ethernet wired. Both machines tell me when there are updates, and I update right away with no problems til 4 or 5 days ago. Now with all except mint, it updates itself, I get a message
Failed to download package files
check your internet connection
A box comes up saying I have updates to install, then checking for updates, then either I have 143 kb will be downloaded, or I think it's 7..kb , I forget the number with that one. the bigger updates seem to work at least so far, and I can't click on anything to get the details of updates. When I click on settings, the computer goes to the software and update settings. So I just click on install now and give my password. the box comes up saying installing updates, downloading under it, then the above message. I'm trying to keep everything updated, but I'm wondering if there is another problem.
I use firefox, chrome and midori as browsers, and I can access them whenever I try to go online. I know I can mess up anything, but I haven't purposely changed a thing, nor have I added new distros in the last month give or take a few days. Ubuntu was the first to have trouble updating, then zorin, open suse, and today peach wouldn't. They stopped updating over the entire period, not all at once. I normally try to go to each distro at least once a week to update while I'm deciding which I want. After the updating problem started I tried to update more. After ubuntu wouldn't update, and the next one I tried would, I didn't try any more, but after the next one wouldn't I tried all of them. My home network and internet all work properly except for that, and all the windows computers are working properly. The setting haven't been changed on the networks that I can see. I do have a cisco router, but this wasn't what that bug was supposed to do, I don't think. My wife and I are the only ones on our network, and she has a windows 7 laptop, that's working ok, I have a windows 7 laptop that's hooked into our tv for watching tv, a windows 8 desktop I really dislike using, can't even give it away. It's just on now for updates, and my 2 linux machines that I play with. What do I need to check, or change to get my updates to work again? I've probably forgot to say something, but I know I'll get asked if I did. I'll appreciate all the help I can get. Thanks
