Hello. I am running Linux Ubuntu v.11.10 64-bit operating system.

Unexpectedly and the first time I have received this type of system warning notification symbol from my Linux Ubuntu operating system. Personally I am concerned and confused over this issue.

I have received in my top of Unity's black bar of the Linux Ubuntu GUI in the right side notification area, a red triangle with a red exclamation mark inside it. Please see the attached image, “Screenshot A”. This is the first time I have seen this. I do not know what to do about it or how to fix it. I assume this notation symbol has serious issues that need to be resolved being red and an exclamation mark in the notification area of my Unity's black bar.        

So following the instructions shown in the “Screenshot A” image I received by clicking on the notation symbol, I select “Check for updates”. After the “Updating cache” and the “Downloading Release” progress bar from some online server completes; I get a window that states, “Failed to download repository information” “Check your Internet connection.” Please see the attached image, “Screenshot B”.  The “Details”, not fully shown in the box, state the following:
 
W:Failed to fetch http://le-web.org/repository/dists/stable/main/binary-amd64/Packages  404  Not Found
, W:Failed to fetch http://le-web.org/repository/dists/stable/main/binary-i386/Packages  404  Not Found
, E:Some index files failed to download. They have been ignored, or old ones used instead.    

I actually noticed however after 10-15 minutes of actually following the instructions shown the “Screenshot A” and still receiving the messages and "Details" in "Screenshot B", that the notation symbol (red triangle with a red exclamation mark) was automatically removed or gone. I took personal note from the “Details”.  I did notice at a later time the red notification symbol automatically returned in the same location again. I performed the same instructions shown in the “Screenshot A” image again. I received the same “Details” again with the same error message as “Screenshot B”. I then noticed after another 10-15 minutes, the notation symbol was removed or gone again. Now, it is possible it will return again soon since it was not in some manner resolved in two instances. I am not sure what triggers it? Some sort of timed system check maybe and that triggers the notation symbol to reappear?    

So in a novice manner following simple instructions, I see this issue is not resolved.

Please provide me instructions and guidance by:

1. Explaining what is going with this issue by:
      A. What this whole system warning process through a notation symbol in Unity's top black bar notification area means?
      B. What exactly pertaining to this particular issue is going on here?

2. Providing me a solution to this particular issue?

3. What normally would be a general solution to issues that involve a system warning notation symbol in Unity's top black bar notification area?      

Please reply.

Thank you!

Your system periodically checks to see if there are any updates available.  Apparently the Update manager was unable to connect to one of the repositories you are using.  It will try again later.

There is something unconsistent in the message you are receiving: it tells you try to retrieve software for a 64 bits system at http://le-web.org/repository/dists/stable/main/binary-amd64/Packages and also for a 32 bits system at http://le-web.org/repository/dists/stable/main/binary-i386/Packages. In my humble opinion, it is the one or the other.

Anyway, the problem is different: the URLs you are pointing to are unexistent for the moment. Try to change the server you are updating from.

Go to System > Administration > Software Sources > Ubuntu Software > Download from: > Other... > Select Best Server. If this doesn't help, it doesn't hurt.

@ DaveBaldwin & pfrancois:

Hello again. Thank you for your comments.

Okay, you are both correct from your comments -- DaveBaldwin gives me the reason and pfrancois gives me the method or steps to resolve it.

Yes, after having my current Ubuntu session running for over 4-5 hours now, that red triangle with red exclamation mark still in it popped up again in that top black bar of the desktop screen. Then I took action...

Okay, I followed pfrancois's steps and it has been going on for over 15 minutes now and the choosing the 'best download server' has stopped in progress. Please see the attached screen clipping. So it is obvious that there are server issues going on here. In that time, the red triangle and red exclamation mark disappeared again. Yet, the the progress bar for the 'best download server' search is STILL running. (I am sure the the red triangle and red exclamation mark will be back again at some point in the near future.)  

Please answer:

1. Could you please explain what is going on here in more distinct terms and (2.) what I can do to get this specific repository 'established' to be updated for lack of a better word?

3. Is this normal to experience or not?

4. Does this at 'some eventual time' resolve itself or not (where I have to intervene manually)? Where maybe I have to resolve it completely NOW?

Please reply.

Thank you!

I don't know why your system is trying to connect to that repository in the first place.  Did you add it yourself or did some software you installed add it?  It has not been normal for me in the 3 years I've been running Ubuntu 8.04.  I think 'Why?' is the first question.

@ DaveBaldwin & pfrancois:

Hello again.

Thank you for both your continued time to help me.

Okay, I have been to the weblink and at first glance from the URLs I provided in my initial post for the question/thread, I see nothing that begins to relate to anything I may of installed, UNTIL i researched a little more and  I saw a weblink on the side panel for "Back in Time" and then I recall a while ago looking up some backup software and I recall something to the effect about "Back In Time: System Restore on Ubuntu". I then checked my Ubuntu installation log book I personally have and see on April 6th I installed "Back In Time" on this Ubuntu operating system. Okay, so this must be the issue then I presume.

I further checked my logs and found the information website that I had originally used:

beginlinux.wordpress.com/2010/02/24/back-in-time-sysetm-restore-on-ubuntu/  

Okay, so I go to this website I previously was on (the weblink directly above) and find that I receive the message, "Sorry, no posts matched your criteria." NOW, THIS IS NOT A GOOD SIGN!!! HMMM..  

Okay, now this raises a few questions, but first I bet you my choice you will tell me...

...keep it -or- remove/delete it from my Ubuntu system, correct -- my choice, correct?????

Well, I figure if it is going to give me issues and it doesn't look too good and reputable now,  and I know what you are ultimately going to tell me ('get rid of it'); therefore I need to way to purge or flush it out of my Ubuntu system.

So how do I do that??? Please explain in detail so my Ubuntu system does not have it any longer and doesn't generate this periodic red triangle with red exclamation mark notation symbol.

I assume it will require some text line commands through Terminal 'to get rid of it' in my Ubuntu v.11.10 64-bit operating system, right? Please explain in detailed steps?

Yes, I bet you are saying I should do a 'complete' ClamAV system scan after I am done, right?

...and finally, HOW does one KNOW or TELL if a third party website has a 'reputable and reliable and even trustworthy' program to install or not into one's Ubuntu operating system???

Please reply.

Thank you!

Hi Bazingeroo

The link you are looking for will be http://beginlinux.wordpress.com/2010/03/24/back-in-time-system-restore-on-ubuntu/

If you followed the process explained there, for uninstalling Back-in-time, you should just issue
sudo apt-get remove backintime-common backintime-gnome 

Open in new window


But before doing that, it is perhaps enough to deactivate the offending repositories. Go to System > Administration > Software Sources > Other Software and uncheck all the entries starting with http://le-web.org/... From now, you wouldn't have warnings form that repository.

It is possible your Back-in-time machine is OK.

No need to run ClamAV, this is not Windows. So you lost your bet. The systems using the keys in the way described in http://beginlinux.wordpress.com/2010/03/24/back-in-time-system-restore-on-ubuntu/ are reliable in my humble opinion.

@ pfrancois & DaveBaldwin:

Hello again.

Well, I personally want to thank each of you for your help with this question/thread. Both of you have played an important part in your comments with suggestions and actions. DaveBaldwin provided the premise of the issues and pfrancois provided the stepped solutions to the issues. I worked things out as the tester. :- )

Okay, so it appears we start figuring things out and getting to the core of the problem with DaveBaldwin's second premise (second comment) by asking myself “Why?”... ...that I should be investigating the source of the issue – the non-updating URL. I investigate it and raise the data and findings in my last comment. pfrancois  provides the solutions with one less significant than the other – my choice of course.

I am going to give pfrancois the Accepted Solution which his comment in actuality provides me the solution to this question/thread (his last comment). I am going to give pfrancois 300 points (greater than half) for the solution. I am going to give DaveBaldwin the other 200 points (Assisted Solution) for the premise and getting me thinking of what may be going on here (his second comment). I would not of developed the data and findings without some direction to start from DaveBaldwin.  
 
Again, thank you both!!!
