apt-get; E: Type 'GPG' is not known on line 20 in source list /etc/apt/sources.list

Ok, so I'm running a kinda old version of Ubuntu - Edgy Eft (6.10).

A friend of mine installed it a couple of years ago and I've never updated anything with apt-get until now.

So, now, it looks like it doesn't have / know how to use GPG.
I enter:

Code:

apt-get update

And I get:

Code:

E: Type 'GPG' is not known on line 20 in source list /etc/apt/sources.list

???

I'd appreciate any help. Thanks

Look at your /etc/apt/sources.list. My guess is something got uncommented by mistake.

Thanks Matir. Unfortunately, I don't think the problem is in /etc/apt/sources.list. I compared it line-for-line with a couple of sources.list samples posted on the web. It is exactly the same.
I considered simply commenting out the GPG lines, but wouldn't that compromise the security of the download?

What do your GPG lines look like? None of my sources.list files contain any lines beginning with GPG (and it does verify signed packages).

Here is what lines 20 onward say:

Quote:

GPG Key Information

wget http://www.kubuntu.org/announcements...iddell-key.gpg | sudo apt-key add

that is a command you would manually type in a terminal to download and install a key..
it should not be in your sources list.

Matir · 05-21-2009, 08:12 AM

Agreed with what farslayer said. For example, my sources.list looks like:

Code:

#deb cdrom:[Ubuntu 9.04 _Jaunty Jackalope_ - Alpha amd64 (20090207)]/ jaunty main restricted

Where did you see samples with that line in it?

Keeping in mind, I'm running a pretty out-dated version (Edgy Eft) ...

Here's the link. This matched my list line-for-line:

Matir · 05-21-2009, 08:33 AM

That is the worst formatting for a source.list that I've ever seen.

Those lines are intended as comments within his text, I believe. The format for Edgy Eft's sources.list is no different from even Jaunty Jackalope. If you replace all instances of "jaunty" with "edgy" in what I posted, that should get you started with the base distro.

To be honest, though, you'll get a much better user experience if you reinstall with a newer version of Ubuntu. Newer and more software, fewer bugs, all the goodies.

It doesn't seem like you have much invested in your current install, so you'd probably just need to back up the files in your home directory.

Ok. Thanks guys. I'll do a backup and reinstall with the latest version.
