Being new and poking my fingers where they probably don't belong, I have a tenancy to blindly follow where Linux posts lead. The above error is the result of one such adventure. I've tried to backtrack my readings, but no luck. Can someone please tell me how to fix this error?

The Update Manager is a function I'd rather not do without.

Thanks for the Help.

PPAs are not all a permanent fixture. Sometimes they just disappear for a variety of reasons.

If you click on the blue links above ^^^ you will see that they are "Not Found".

If you want to remove the error messages you need to remove the repository(ies) from your sources list. There are a variety of ways to do this. If you want to go direct to your sources list, open a Terminal and input the command: gksudo gedit /etc/apt/sources.list

Look for the line(s) and put a # at the beginning. That will make the line(s) a note only and make it/them invalid. Save gedit . Close gedit.

Try updating again.

What distro are you using? if you are in a Debian base usually
fix problems with updating and upgrading

Good luck to you.

I clicked on the links as you suggested and you were correct. They were both not found.
I have not idea what that error message means.
Are we in the right church but the wrong pew?

Remove the links with errors from your source list.

What distro are you using? if you have gnome as your desktop environment you can use gedit

Look at all the links there and the one with errors put at # infront of them.


Good luck to you!

As for the gnome question. I have no idea.
This is your ballpark not mine.
I'm here for the help.

1) Don't use sudo with gedit. It's a graphical program - so you should use gksudo. Background here: http://psychocats.net/ubuntu/graphicalsudo

2) If you haven't got gedit, install it. Connect to the Internet. Open a Terminal. Issue the command: sudo apt-get install gedit

It worked. I had to download gedit, but it all worked. Good advise.
However, the bad news, isn't there always bad news. Those ppa sites were not listed.
So, where did the Update Manager get them from?

I found them! Under Software Sources > Other Software
Sometimes it pays to be lucky. So says the wizard.
I just ran the Update Manager and it works with no errors.

Thanks guys. You're the best for coming to my aid. Don't worry. I'm sure I'll be back with another oops.
I couldn't be that lucky.
