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?
