Permission issues when updating

noncomputergeek · 02-09-2011, 06:20 PM

Hey guys. I messed something up big time in ubuntu 10.10.
I was trying to update it but i somehow took off the rights for debian packages (i think i denied the rights when it asked for my password, not really sure, it's been a while since this happened.) and now i cant install them. Any clue how to fix it?

I think that message is just telling you that the AMD package(s) you're trying to install are not signed, so you have not way to know if they have been forged by some cracker. I.e., use at your own risk.

The thing is i remember it asking for my password or something like that but i was distracted and accidentally denied the rights for something. It's not an "use at your own risk" thing because it just wont let me install it. Is there any way to figure out if i have denied debian packages permission on my computer?

Well, possibly you replied "No" when you were asked to install the Debian repository signing key.

I'm not using one of my Ubuntu systems right now, but I think that the apt-key command is the one you need to import the key, although there may be a "key management" option in the package kit GUI that Ubuntu uses by default.

Try a Google of "Debian signing key install" or something similar for signing key information.

i think what you just said is exactly what happened.
so just putting "apt-key" in terminal will get the key or what?
I'm so lost man :/

Are you using Debian sources in Ubuntu? If so, you should not do this.
Are you using any third party repos in Ubuntu? This includes those all too problematic and often troublesome PPA repos.

See this on using apt-key:

Also see this:

And for those unpredictable PPA repos:

Don't despair! You'll find your way (to the promised land of FOSS) soon.

So, I started one of my Ubuntu systems, and lo!, right there in the system menu I found an "Apt key management" item. (Of course, I probably installed it when I was setting up my system. I always install several update managers since they have different strengths and weaknesses.) Anyhow, I suggest you either follow tomcd's advice, or go to your system menu item and see if there's something in there that looks like it will let you "manage" your repository keys.
