E: Some index files failed to download. They have been ignored, or old ones used instead.

Here's my /etc/network/interfaces:

auto lo
iface lo inet loopback

And my /etc/resolv.conf:

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 192.168.0.1
nameserver 127.0.0.1

Obviously internet works (I'm using this computer right now), but the update-manager, the software centre and synaptic don't. Is something wrong with my configuration..? BTW sorry OP I can't help you there :(

[weryl]

BTW OP I apologize in advance if our problems end up being unrelated...

[Donovan.Quinn]

Had the same issue. Tested changing DNS settings and this seemed to resolve the issue.

[Rommie]

This just started happening to me today in Software Centre as well...

"Check your internet connection"

Software Updater is also affected.

"sudo get-apt update" fails as well:

"Something wicked happened resolving ca.archive.ubuntu.com" etc...

Clean install of 12.04 on new HD. Formatted downloaded new image and reinstalled to make sure.

It would appear that the "Default" Software Source is to blame (for Canada anyway). I fixed my issue by going to Edit -> Software Sources and changed "Download From" to "Other" then clicked "Select Best Server". After a minute or two, I was back online. Fixed the issue for "Software Updater" too. Hope this helps.

[meraj21]

I have the same problem with no solution.

[BarfBag]

I suspect this has something to do with the repos. Downloading anything from them is slug slow tonight. I suggest trying again in the morning.

This looks promising, I'll test that as soon as i get back!

[EDIT] It worked, thanks a lot!
