"failed to check for updates" posix error

What is this? How can I fix it?

In case anyone cares I solved my problem. It turned out to be some funky firewall thing ... I don't know why ... but flushing the firewall rules fixed it. Below is the solution that worked.
Another solution has been proposed that requires use of the Terminal.
Type "sudo ipfw list", and you will receive a list of ports (tcp/ip) with their open or closed status.
Then type "sudo ipfw -f flush" to reset the ipfw list.

Windows Update failed to check for updates with error 0x800B0001

Hi all,
I have a WSUS installed on a Windows Server 2008 R2 box, I have a new Windows Server 2012 box (joined to domain) that cannot get updates from the WSUS, whenever I try to search for new updates I receive the following error in event viewer:
Windows Update failed to check for updates with error 0x800B0001
Note: I cannot see the Win2K12 server in the WSUS console under computers node.

I couldn't get it to run even after installing the mentioned KB fixes. So I investigated the error myself, and found a "hack" that seems to fix the issue. Wrote up a small piece on it here:
http://tplive.azurewebsites.net/2013/12/windows-update-error/
You and about a thousand other people have reported "I had already installed [the update], but installing it AGAIN fixed the problem.", which is almost assuredly a simple indication that the original installation of the update failed, and you simply did
not recognize that the installation of the update was not successful.
The fact that the /selfupdate folder was corrupted (read: missing files) pretty much says it all. There's no bug. Your installation of the update simply failed. (Or, the server wasn't healthy to begin with and you got what you got.)
Bottom line: The only known cause for a client-side 0x800B0001 error code is that the WSUS server has not been
properly and completely patched.

Mac OS X 10.6.8, receiving error message "Failed to check for updates. The operation couldn't be completed. Operation not permitted." How to fix?

When I try to update my software, I'm receiving the error message "Failed to check for updates. The operation couldn't be completed. Operation not permitted."
I'm using Safari 4.0.3. Yes, I know this is an old version of Safari - I can't update it, or any other software on my MacBook. Should I just wait for the Lion OS, or is there any kind of fix a non-technical Mac user like me can attempt without screwing up her laptop?
I've tried clearing my cache and resetting Safari already - doesn't help. I've also tried to update after disabling my (Norton) antivirus software, thinking that might be interfering. None of these help.
I don't know if it's a related problem, but also I can't download .pdf files from the internet, although I used to be able to.

You should use the NortonAV uninstaller to uninstall it. Disabling the dreadful thing in the past hasn't always been sufficient for it to cease creating system havoc. The Mac NortonAV version has a long and well-earned reputation for doing truly seriously nasty things to OS X. Shame on Comcast for inflicting NortonAV on its Mac customers. It's not a matter of if NortonAV will mess up OS X but when and how badly. I can't help but wondering if some setting in your Norton AV has decided that NortonAV, rather than you, will be making executive decisions about what you are allowed to install on your computer and is keeping that fact a secret.
After you are done uninstalling Norton use the finder to search for any Norton files that the uninstaller might have missed. Add the option to search for invisible files.
After you have removed all the Norton bits and pieces restart in safe mode by holding down the shift key right after the startup chime. Keep holding down the shift key until you see the Apple logo and spinning gear. Safe mode does some maintenance tasks which means a much longer than normal startup time. Use Disk Utility to repair permission
If your Mac works normally in safe mode restart. If things still aren't fixed you might want to give another shot at reinstalling Snow Leopard from the install DVD and applying the Mac OS X 10.6.8 Update Combo before taking your Mac to the Apple Store.
If you feel the need to run AV software on your Mac use ClamXav in manual mode. It's donationware and doesn't seem to cause the litany of weird problems that are associated with other AV software.

Go to Wifi Settings and then select your Wifi Network. Tap the blue arrow to go into Wifi settings and then select the DNS tab.
Set the DNS to 8.8.8.8 and then go back to the software update page.
This time it shall work.
I tried it on an iPad 1 running iOS 5.0.1 but I am sure this shall help.
Do rate me and reply if it works.

This device does not have a sim card in it. Could this be the reason or am I missing something when I am trying to update.
Yes. You can't update or restore any GSM iPhone without a valid sim card installed in the phone. The sim card need not be activated, but it must be valid & present. If you want to update, you need to get a sim card.

When I try to check for updates, an error message appears with no details. How do I get and check the updates on my new intex cloud fx phone?

I have a new Intex Cloud Fx phone. In this, I go to 'Device in formation' and try to update the device by pressing update now, I get an error message that says 'an error occurred while checking for updates'. Also, it does not respond to the' last updated' command. When I press 'more device information' I can see’ OS version Intex_Cloud_FX_V07’. I have tried all kinds of procedures suggested on the net and elsewhere but have not succeeded in updating my phone, so far. This includes resetting the phone. I am using a Wi-fi connection. It seems that quite a few persons are facing this problem. There have been suggestions ranging from 'there is a bug' to 'there are no updates'. So, the problem persists, with no end in sight. I feel Mozilla should look at it.

Hi!
Thanks for contacting us today! I understand you are having issues with updating, and using the device.
I believe that we are aware of the update issue however, it is ultimately the carrier/ manufacturer to provide updates. Please contact the respective company for assistance.
As for device using, and things not working. Please provide us with more details. (Note: the bug may have already been fixed, but is available in a later update).
Thanks!

I cannot receive updates. When I check for available updates, it reads: "failed to check for updates."

I have set up automatic updates weekly. Each week I get an error message. I am unable to manually check for updates either.

Do you have Season Pass for Breaking Bad? You'd need that to see the show in Available Downloads.
Take a look at this Apple doc for more info -> iTunes Store: Download options when purchasing TV seasons, Season Passes, Multi-Passes, movie bundles, music box sets, or individual movies or TV episodes

HT201210 how do I correct - Unable to Check for Update an error occured while checking for a software update.

error message: Unable to check updates. an error accured while checking for a software update.

It is all in your WIFI.
I have 2 internal Wifi networks at home. In one (family) the software update works immediately, in the other one (guess) it gives me the same error "Unable to Check for Udpate" ... The guess network I did set up carries some restrictions being the reason why the update does not work.
