Ubuntu 12.10 not updating after upgrade from 12.04

Question

I upgraded from Ubuntu 12.04 to Ubuntu 12.10. After this it is not updating . The software updater gives this error:

I am not able to install anything from Software Center; it just asks to use this source and after that it just keeps on querying software sources and nothing happens.

The contents of /etc/apt/sources.list are:

Solution 1

I've had this problem myself with Ubuntu 12.10. Be careful what you do to try to fix this - I ended up re-installing 12.04 to fix my machine. With that said, there is a bug report on Launchpad (sory, can't find it) that explains how Ubuntu 12.10 enables a DNS feature dnsdmasq by default, which messes up a lot of systems. This article explains how to disable dnsdmaq. http://www.ubuntugeek.com/how-to-disable-dnsmasq-in-ubuntu-12-04precise.html

Verbatim from the article: "

You need to edit /etc/NetworkManager/NetworkManager.conf file

$ gksudo gedit /etc/NetworkManager/NetworkManager.conf

and comment out the following line from

dns=dnsmasq

to

#dns=dnsmasq

Save and exit the file

Now you need to network-manager using the following command

$sudo restart network-manager

"

Hope that helps.

Solution 2

I finally found the solution to the problem of ubuntu 12.10 not getting updated. There actually was some problem with the proxy, so what I did was as follows:

I ran gksudo gedit /etc/apt/apt.conf to edit the apt.conf file, then

added the line below in the apt.conf file:

Acquire::http::Proxy "false";

now everything is going as smoothly as it was.

Solution 3

Sounds like an internet issue. (Unable to connect to X.X.X.X:XXXX:) Try disabling your Firewall, and getting out from behind any proxies you may be using. If that doesn't fix it, I'd recommend changing your DNS. Your ISP may be giving you a lame DNS server (or maybe you manually set up a lame one. ;)

Anyway, to do this, just set your DNS servers to 208.67.222.222, 208.67.220.220 (that's OpenDNS; there are others. Pick one that you like, but, most importantly, pick one that works.) If you don't know how to do this, detailed instructions can be found here.

Solution 4

I solved this. When I ran

vi /etc/apt/apt.conf

I found in this file strange config with this the IP address 41.191.27.92:

Acquire::http::Proxy "http://41.191.27.92:8080";

Delete this line and add:

Acquire::http::Proxy "false";

After that, run:

sudo rm -rf /var/lib/apt/lists/* -vf 
sudo apt-get update

And all works perfectly!

(I don't know why I found that IP address in the configuration file though.)

You can try this out in the terminal sudo apt-get update -f and then sudo apt-get update. Hope this works.

[gunjan parashar]

after sudo apt-get update -f i am getting the same error

You may not be connecting to the internet, try this: askubuntu.com/questions/135932/…

[daslinkard]

Did you recently upgrade to 12.10 and it worked previously? Also what happens when you reboot your system and try to update?

[gunjan parashar]

no initially it was working correctly once but after after trying to install something from software center it was asking to add universe to the repository then i checked some of the ppa form the other software tab of the software sources , even though after undoing the things it's not updating , plz hep me out thanks in advance i love ubuntu do not want to switch to windows

[nilsonneto]

@gunjanparashar - please add to your question what 10.4.42.15:8080 actually is - looks like you have a proxy - how have you set this up? Are you using a proxy like this Q&A? askubuntu.com/questions/23666/apt-get-does-not-work-with-pro‌​xy/…

[Admin]

Please check with your NETWORK PROXY settings. :) I solved it by changing the mode to normal as I use manual in the university and automatic at home. Thanks

[gunjan parashar]

[gunjan parashar]

@gunjanparashar don't forget to mark an answer as "Accepted" if the answer helped.

So... you're already using OpenDns? Try a different one, then. Also, do you normally have internet trouble? (e.g., frequent connection errors when surfing the web, Wi-Fi is unstable, etc.

[JamesTheAwesomeDude]

Hey... another good DNS provider is Google's DNS - they don't screw up nxdomain like OpenDNS does. Primary server is 8.8.8.8 secondary 8.8.4.4.
