Can't Download?

Try changing download location in administration-->software sources. If this doesn't help please post your /etc/apt/sources.list file here.

Here's the sources.list file:

deb cdrom:[Ubuntu 7.10 _Gutsy Gibbon_ - Release i386 (20071016)]/ gutsy main restricted

You say you're trying to download some applications, which ones are trying to download?

That may help somebody else check whether its happening on their system as well.

Also, can I suggest disabling the Automatix repositories and reloading your sources (assuming you're using Synaptic) and then trying to download the applications again.

Yet another Automatix problem ... :)

Those web repositories are the problem, i don't think there is such a thing at all. Try removing them from all the lines:

deb http://ca.archive.ubuntu.com/ubuntu/ gutsy *web* multiverse restricted universe main
deb-src http://ca.archive.ubuntu.com/ubuntu/ gutsy *web* multiverse restricted universe main #Added by software-properties
deb http://security.ubuntu.com/ubuntu gutsy-security main restricted *web* multiverse universe
deb-src http://security.ubuntu.com/ubuntu gutsy-security main restricted *web* multiverse universe #Added by software-properties

You need to open sources.list with sudo to edit it, so instead of opening it normally type in a terminal (applications-->accessories):

sudo gedit /etc/apt/sources.list

If you can't still get it to work here are five lines that work for me (all updates enabled same as in yours, no automatix of course) just copy all you have somewhere and put them instead:

deb http://archive.ubuntu.com/ubuntu/ gutsy main universe restricted multiverse
deb http://security.ubuntu.com/ubuntu/ gutsy-security universe main restricted multiverse
deb http://archive.ubuntu.com/ubuntu/ gutsy-updates universe main restricted multiverse
deb http://archive.ubuntu.com/ubuntu/ gutsy-backports universe main restricted multiverse
deb http://archive.ubuntu.com/ubuntu/ gutsy-proposed universe main restricted multiverse

Everything worked except these two:

http://ca.archive.ubuntu.com/ubuntu/dists/gutsy-updates/Release: Unable to find expected entry web/binary-i386/Packages in Meta-index file (malformed Release file?)

http://ca.archive.ubuntu.com/ubuntu/dists/gutsy-backports/Release: Unable to find expected entry web/binary-i386/Packages in Meta-index file (malformed Release file?)

Thanks Wrwrwr, that solved my question.

The real question is how did those "web" got in there? I had the same problem and I know I didn't add this "web things" in sources.list. I managed repos inside synaptic, so how did it add them in there?

I also have "web" mentioned in my sources.list. Maybe it came from firefox because I installed totem-mozilla through firefox.

Yes, firefox ask me about this : « Do you want to enable the following component: 'web'? »

I tracked this down and fixed it this evening. See bug #202170 for details.
