I am a new Linux user working on a Raspberry Pi. In response to the command "sudo apt-get install i2c-tools", I received the following error messages: Reading package lists... Done Building dependency tree Reading state information... Done Suggested packages: libi2c-dev python-smbus The following NEW packages will be installed: i2c-tools 0 upgraded, 1 newly installed, 0 to remove and 13 not upgraded. Need to get 59.5 kB of archives. After this operation, 223 kB of additional disk space will be used. Err http://mirrordirector.raspbian.org/raspbian/ wheezy/main i2c-tools armhf 3.1.0-2 Temporary failure resolving 'mirrordirector.raspbian.org' Failed to fetch http://mirrordirector.raspbian.org/r....0-2_armhf.deb Temporary failure resolving 'mirrordirector.raspbian.org' E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing? I would greatly appreciate any help in understanding what the problem and how I can rerun the command successfully. Thanks Jerry

Did you run You need to always do this before you run 'sudo apt-get install'.
The 'update' command updates the packages list of your repository.
After that, when you run 'sudo apt-get install <package-name>' the package will be found in the correct location.

This link also mentions 'upgrade' and 'dist-upgrade' too https://askubuntu.com

Higgsboson:

I followed your suggestion and ran the "sudo apt-get update" command which outputted
the following error messages:

Err http://archive.raspberrypi.org wheezy Release.gpg
Temporary failure resolving 'archive.raspberrypi.org'
Err http://mirrordirector.raspbian.org wheezy Release.gpg

W: Failed to fetch http://archive.raspberrypi.org/debia...zy/Release.gpg Temporary failure resolving 'archive.raspberrypi.org'
W: Some index files failed to download. They have been ignored, or old ones used instead.



I then went back to the original error messages for the apt-get install command and noticed the line:
"Temporary failure resolving 'mirrordirector.raspbian.org'
Failed to fetch http://mirrordirector.raspbian.org/r....0-2_armhf.deb Temporary failure resolving 'mirrordirector.raspbian.org'

I then used the URL it said it couldn't resolve and was able to access the file on my browser so I know it is there.

Finally I looked at the sources list of my system (/etc/apt/sources.list) and it contains the line:
deb http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi

This line doesn't seem to me to be correct as the URL does not match the one in the error message.

Could I solve the problem by just replacing "deb http://mirrordirector.raspbian.org/raspbian/ wheezy main" with
"http://mirrordirector.raspbian.org/raspbian/pool/main/i/i2c-tools/i2c-tools_3.1.0-2_armhf.deb" in the sources.list file

Since I am a new user of linus I'm reluctant to change it without first running it by an experienced user. Do you think that this is the problem ?

Thanks for your help

Jerry

BTW: I know this reply is a bit wordy but I come from a System Test software background and was
always told to put in as much detail as possible when writing up a bug.

This won't work because the mirror site for your repository in /etc/apt/sources.list is correct.

It seems you may have an internet connection problem. Are you using wifi? apt-get-installation-doesnt-work-on-raspberry-pi

Higgsboson:

Yes I am using a Wi-Fi connection. After looking at the URL you pointed me
to, I reconnected my Raspberry Pi directly to the LAN cable and retried the two commands.
Unfortunately this did not fix the problem. I was wondering if sending to another
mirror site would be worth trying and if so how would I determine what I have to
put in the /etc/apt/sources.list file.


Thank you for all your help

Jerry

Sometimes the Raspberry mirror goes down in my experience. You may want to try waiting a day to see if the problem fixes itself.

This link shows the 'master' repos for Raspbian and all its mirror sites depending on your location: https://www.raspbian.org/RaspbianRepository

If you choose a repos from your country of origin (or near to it) then the downloads should be faster.
Since you have 'mirrordirector' in your /etc/apt/sources.list, then it is part of the 'mirror redirection system'. https://www.raspbian.org/RaspbianMirrors

So you may indeed try a different mirror repos to see if it helps.
Simply delete your mirrordirector url in /etc/apt/sources.list and replace it with an url beginning with 'http...'.

Is there a new error message you're getting?

can u ping google.com while logged into your rasberry pi ? (<ctrl> + c will stop command)

Guys:

As per suicidaleggroll's suggestion, I retried the commands and they all worked perfectly :-).
I really appreciate all the suggestions that were sent to me and because of the time spent
trying those suggestion and doing some reading based on them, I feel I had gained some additional
knowledge and experience with Linux. As a wise man once said: You learn a lot more from your failures
than you ever do from your successes.
