TS3991 unable to update due to invalid signature

Why am I not able to update itunes due to an invalid signature

Hello Shelly,
It sounds like you cannot update iTunes because a message about an invalid signature. I recommend downloading this update directly from our site and installing that file instead:
iTunes 11.0.4

Thank you for posting in the Apple Support Communities.
Best,

[SOLVED]Unable to upgrade due to invalid signatures

I thought that maybe it was a temporary issue with the mit gpg server and it would resolve itself, but it has persisted for 2 days now. I have tried refreshing the key list with pacman-key --refresh-keys. I've tried purging the files with pacman -Sc and downloading again, still no dice.
The output is:

I don't know if maybe that one key that isn't being found on the server could be the issue? I have tried several different key servers and they all output the same information. Which is to be expected I assume.

Yup, followed the instructions on the pacman-key wiki page. I have been upgrading fine for months sincfe then and was able to upgrade with no problems the day before and then all of a sudden now I can't. I am pretty sure I haven't changed any settings anywhere that would have caused this. I'm using SigLevel = Optional DatabaseOptional TrustedOnly.
EDIT:
I changed to SigLevel = Never and pacman reported that a lot of the package files were corrupted and asked if I wanted to delete them. I deleted them and ran pacman -Syyu again, everything working now.
Why didn't pacman tell me the files were corrupted and ask if I wanted to delete them while I was using SigLevel = Optional DatabaseOptional TrustedOnly?

I have iphoto on my apple airwave. It is needing upated, but I am unable to update due to my exhusband. It was purchased under his itunes account. I can no longer even see my pics. What do I do.

I have iphoto on my apple airwave. It is needing upated, but I am unable to update due to my exhusband. It was purchased under his itunes account. I can no longer even see my pics. What do I do.

Can I back up my iPhoto library without being able to get into it? Such a mess.
Just try what LarryHN recommended. Move the iPhoto application from the Applications folder to the Trash, then go the main page of the App Store, sign into the store menu with your AppleID, enter iPhoto into the Search Field. When iPhoto is found in the store, look, if you can buy it for free. Probably there will be a "Get" button beside the application. Then you can install it for free.
Before you run the newly installed iPhoto, make sure you have a backup. You should really not risk to run a new iPhoto version on your iPhoto library, before you copied the iPhoto Library to a different drive.
iPhoto needs to convert the library to a different format, and that can go wrong in rare cases, but it happens. You simply need to have a copy of your library before you risk the library upgrade.

When downloading updates for Quicktime 7 and Itunes 10 I keep getting an error saying that files shared by these updates has an invalid signature and that the downloaded has been removed.

When downloading updated for Quicktime 7 and Itunes 10 I keep getting an error saying that files shared by these updates has an invalid signature and that the downloaded has been removed. If I don't get that message I get a message saying that the download was unsuccesful and that in order to download I need to go to tools and then select dowload only. Please help I really want to update my iphone!

Thanks for helping out, but I already tried these steps.
I even tried this on a iMac with similar results. The only difference was that the errorcode was called 2001 instead of 21.
Today I took the phone to www.iphoneambulancen.dk. A guy (in Aarhus, Denmark) that specializes in iPhone repairs. I figured, that given his occupation he'd seen most errorcdes. Two hours later, he called me back, and told me that he had replaced the battery.
So, it turns out that a broken battery can cause this behaviour.
But thanks again

HT1386 Unable to update due to apple icon stuck. Can't connect to iTunes due to unable to put in passcode

Unable to update due to apple icon stuck. Can't connect to iTunes due to unable to put pass code into phone.

http://discussions.apple.com/thread.jspa?messageID=12206661&#12206661
I had the same problem. It appears that the servers chuck a hissy fit if you don't download your purchases in a timely fashion. I used the 'report a problem' feature in my iTunes account to contact customer support via email. They replied about 24 hours later, reset my download cue and the problem has now been resolved.
Hope this helps you solve your issue.

When updating iTunes to 11.4 I get the following error: "Files Shared by these updates" has an invalid signature. It will not be installed. Running Windows 7 64-bit.

For general advice see Troubleshooting issues with iTunes for Windows updates.
The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.
Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.

I can't update iTunes software due to "Invalid Signature" issue

Everytime I try to update my iTunes software it says it has an "Invalid Signature" and won't be installed. For the latest big update I had to totally remove it and reinstall it from scratch. Now I still can't update it and of course I keep getting messages telling me to update to the latest version. I am using Windows XP and have AVG Internet Security 2012 full version. Can anyone help me with this. It may be a "settings" issue but I'm not sure which settings, ie. Windows, AVG or iTunes. AVG have said its not their issue.
Please help

Can you repair Apple Software Update?
Go to START/ALL PROGRAMS/Apple Software Update. If it offers you a newer version of Apple Software Update, do it but Deselect any other software offered at the same time. Once done, try another iTunes install
If don't find Apple Software Update in all programs, you can do it in control panel, add and remove programs.

cannot remove an older version of bonjour
Download the Windows Installer CleanUp utility from the following page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
To install the utility, doubleclick the msicuu2.exe file you downloaded.
Now run the utility ("Start > All Programs > Windows Install Clean Up"). In the list of programs that appears in CleanUp, select any Bonjour entries and click "Remove", as per the following screenshot:
Quit out of CleanUp, restart the PC and try another install. Does it go through this time?

ITunes upgrade won't download due to 'invalid signature'

I have a 2nd Generation iPod Touch which will not download any iTunes software upgrades when prompted to do so. The first error message advised me to go to Tools, then Download Only (which I did). The next error message said that iTunes has an invalid signature.

Thanks very much, NathalieS

I would delete the download and redownload the updat file. It is located here for a PC

My PC is telling me apple software updates have an invalid signature ?

I'm having real problems with updates to ITunes and all Apples software, every time i try to download I get "Invalid Signature" and it will not load. Even when I access ITunes help the page gives me a warning that it dose not have a valid certificate and is not safe to continue.

What is the exact wording of the message?
It sounds like you have exceed the five computer maximum. If you computer crashed and you have to reinstall the operating system, and you now authorize the computer again, you will have two computer authorized unless you deauthorized the computer before it crashed.
As discussed in the article yo can deauthorize all (but only onceper year).

After searching around a bit, I found http://www.archlinux.org/news/having-pa … -packages/
I tried that, but I think it doesn't apply to me, as I've installed Arch just last week. Running
pacman-key --init
pacman-key --populate archlinux
does not give me pacman.conf.pacnew, as I think is to be expected as I already started with an up to date pacman, right?
The contents of my pacman.conf are here: http://pastie.org/private/w5iwbcwknmaiffhxchzekq
I tried throwing away the packages with "pacman -Sc kile" and reinstalling with "pacman -S kile", same result.
Any ideas how to resolve this issue?
(Probably unrelated, but I'm running Arch in a VirtualBox, with xfce, Linux version 3.5.4-1-ARCH)

karol wrote:1. You should run 'pacman -Sc' not 'pacman -Sc foo'. 'foo' doesn't do anything here (no harm either) as 'pacman -Sc' doesn't take arguments.
2. The issue you faced has been covered in https://wiki.archlinux.org/index.php/Pa … 9.22_error (next to last question) yet people keep banging their heads against it. Have you read the 'Troubleshooting' part of Arch wiki article on pacman? Was there anything unclear? Maybe we can phrase it better?
I did not have *.part files, only 0-byte-files with the correct name, so that solution does not apply to my problem. Besides, the problem I had was that pacman said "Signature from "User <[email protected]>" is unknown trust, installation failed", so I tried the solution above the one you mentioned, which failed. As soon as I understood something was wrong with my cached files, it was solved quite easily.

Installation of *.pkg fails to due to invalid digital signature

I am a facing a strange issue, installation of quite a few pcakges downloaded from known/trusted sites fails due to invalid signature. To name a few, MS Silverlight, Google video chat pluging and GNU Emacs.
Please see the attached image for error message when I tried to install google chat pkg. It is strange that, digital signature verfication fails every single pacakge. Any clue what is wrong and how can this problem be resolved.
TIA

Invalid signature so update to 11.01 wont load

When I try to update to Itunes 11.01 Iget a reply "Files shared by these updates " has an invalid signature. It will not be installed. I am trying to update from 10.6.3.25 to 11.0 but the files refuses to go past initial download. Any one know what I can do.
I'm using my PC on Wndows 7 for ITunes.

Hi Mark
You say everything is up to date? And you have tried reinstalling all the CC apps? Is Windows also fully up to date? Hmmm... That could be tricky.
What version of Windows are you using? Have a look in Task Manager > Processes and see if 'CEPServiceManager.exe *32' is listed as running?
If not, I don't know where it would be installed from, and we'd need someone like Chris Cox to join the thread to tell us, but my guess is that it would install along with the CC Desktop Application Manager. Windows 8.1 can be problematic, and a bit fussy about the order of things, and it is definitely worth adopting best practice when installing your CC apps. That means restarting your computer, and right clicking the Desktop Application manager and running as Administrator.
How many CC apps are you running? If just Photoshop, Bridge, Expansion manager etc. then - and I hate to say this - perhaps have another go at reinstalling, but run the Cleaning tool after uninstalling.
Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6
Try some other Extensions before the Tony Kuyper's TKActionv3. GuideGuide is a favourite of mine, as well as Dmonzon tools, and maybe Russell Brown's Flypaper Textures.
I have to say that I have had problems with the CC Extension Manager a while back, but simply reinstalling just the Extension Manager fixed it. Perhaps CEPServiceManager.exe *32 installs with Extension Manager? Heck, maybe start with just trying that before reinstalling all your CC apps.
If you are still stuck, I'd risk sending Chris Cox a PM, but not until you triple check that your video card driver is up to date from the card maker's website.
Good luck, and be sure to let us know how you get on.
