Requires installation of untrusted packages

[Hado]

I had precisely the same error. And switching to the main server made the proper fix.
Thanks guys!

and when i run "sudo apt-get update" it gives me the following message: (the error message is at the bottom.)

Your help will be highly appreciated.

Thanks in anticipation.

See the link I gave you. It works for the default repositories.

If you need more specific assistance you need to provide us with more details. What repository are you trying to add ? what error message are you getting ?

[bodhi.zazen]

You will need to add the keys to those repositories manually.

Sir,

Thank you for helping me out.

the links you posted and all the information in there was new to me. so i didn't know really what to do. but I followed as much as I can and hopefully have fixed it all.

here's the information I get now when I run "sudo apt-get update" in the terminal:
Is that OK. I guess nothing wrong now, its just problem on the server, they no more have the pages, which is my computer shows 404 error.

You seem to be using a lot of ppa ....

What ppa is that ? You need to go to the ppa and confirm you have the correct line in /etc/apt/sources.list

See the links I already gave you and the project home / ppa page.

If your sources.list is correct, you will need to file a bug report with the project so they can fix their repo (ppa).

Grrrrr WTF???

I get this message no matter what I try to install. From OpenOffice to Gnome Tetris. Nothing installs at all, even if it's in the main repository.

I don't know how to go about getting every single PPA key needed. All I did was install (supported) updates from update-manager and now nothing will install.

So thanks a lot for another great update. I think I'm just going to remove update-manager and never update anything ever again. All it does is just break stuff.


lol why can't anything ever be simple?

[coolman98]

fix worked for me in maverick

Can you run apt-get update from a terminal and post the error message ?
