i could really do with some help, basically every package is seen as untrusted and it is stopping me from upgrading or updating, and to install packages i have to do it from apt-get and say that i trust the source.
View 9 RepliesI have managed to fix the problem where Ubuntu did not recognize my admin password,but now I have another problem.I tried to install an application from the Ubuntu Software Center.I entered my admin password, when I was asked to do it.Then,I got this message: ''Requires installation of untrusted packages The action would require the installation of packages from not authenticated sources.''
And I am not allowed to install the program.It happens regardless of the app I'm going to install-thus I can't install anything! I use Ubuntu 10.10.
I have just recently installed ubuntu on a new (new to me at least) machine and am have some trouble installing common programs from the USC. Like Amarok, BlueFish.. ect. Pretty much everything I have tried says it requires download from untrustworthy source. All installed fine on my laptop. I am running natty narwahl on this computer and 10.10 on my laptop.

View 7 Replies View RelatedI want to start using videos/music files downloaded from untrusted sources (BT,Sharing Forums, etc.). Haven't made this a habit b4 because of the security risks. I want to take steps to reduce the risk & protect my computer from anything malicious. What are some good choices for this? The biggest step I took so far is using Ubuntu since it's very virus resistant, but other threats do exist out there (rootkits, malicious scripts, etc.). When downloading files from untrusted sources, who knows what may be hidden inside.Some options I'm thinking about:
1) Using a VM (with Ubuntu installed inside) & playing the files inside the VM. If anything malicious happen, it would be trapped inside & I could easily revert to a clean snapshot.
2) Using AppArmor to restrict what the files or program used to play the files can/can't do. AA seems very complicated though.
Are the above overkill? Would it be sufficient enough to just open these files on a non-admin user account since no access to root or sudo?
I just upgraded to 10.10 and found that when I visit the secure area of my business site, it throws an Untrusted Connection error (on FireFox). It works perfectly fine with Chromium on Ubuntu though. And it works just fine with all kinds of browsers on Windows Vista too. is this a known issue on FF with the new Ubuntu?

i'm getting an error when trying to run my update manager. i had been having a problem updating my opera, but just today my current package isn't downloading. the error i am getting is:
"Requires installation of untrusted packages The action would require the installation of packages from not authenticated sources." the detail info is:
"computer-janitor computer-janitor-gtk empathy empathy-common icedtea-6-jre-cacao icedtea6-plugin libc-bin libc-dev-bin libc6 libc6-dev libnautilus-extension1 nautilus nautilus-data nautilus-sendto-empathy openjdk-6-jre openjdk-6-jre-headless openjdk-6-jre-lib opera ubuntu-docs upstart"
i tried to just ignore that, so i unclicked it (just wasn't interested in dealing with it right away), and go on {this is how i had been ignoring the same error on my opera update for a week or so} --- and so when i tried going on, i got same above error except with this detail:
"empathy empathy-common icedtea-6-jre-cacao icedtea6-plugin libc-bin libc-dev-bin libc6 libc6-dev libnautilus-extension1 nautilus nautilus-data nautilus-sendto-empathy openjdk-6-jre openjdk-6-jre-headless openjdk-6-jre-lib opera ubuntu-docs upstart" ps- i am a pseudo novice who is trying to learn how to use the terminal, so if it's not too much of a pain, i like terminal directions,
What if someone tampered with some important security updates, and suddenly you get a rootkit instead?
View 4 Replies View RelatedI've read and re-read everything I can find about AppArmor, to no avail. On the whole, AppArmor isn't for me. However, rather than give up on it completely, I have an idea: create a profile that I could use as a template for any untrusted application, with the aim of 1) blocking it from network access and 2) blocking it from installing other applications. I've got as far as creating an empty profile:
Code:
# Generic AppArmor Profile for UntrustedApplication
#include <tunables/global>
/usr/sbin/UntrustedApplication {
#include <abstractions/base> }
What do I need to add to make this profile 100% permissive, except for the two exceptions stated above?
A few weeks ago, i installed Ubuntu Desktop 10.10. I installed several of my previously used programs and am now having trouble with the update manager. It refuses to download updates; insisting that it does not trust the source. The details in the error message indicate that the problem is with a package for Banshee Media Player. I am posting a link for a video I made that displays this problem. [URL]

View 2 Replies View RelatedI have a repository that isn't signed (and would be a pain to get the administrator to sign)need to use APT::Get::AllowUnauthenticated to install anything from this. However, packages from this repository may have dependencies that I want to download from the main Debian repository and I don't want to install these if can't be authenticated.Is there any way to configure apt-get to allow packages to be unauthenticated from one repository, but forces authentication for all others or am I forced to manually download the dependencies and install myself in this scenario?
View 4 Replies View RelatedAt the login webpage of <[URL]>, the Time Warner Cable (TWC) Webmail site, I am immediately confronted with a warning that the Security Certificate is invalid & that the site is untrusted. This occurs with Firefox, Seamonkey, & Konqueror. This does not occur on Microsoft or Apple systems; I have checked other colleagues machines. I have manually overridden the warning & everything functions fine. I have contacted TWC & am awaiting their tests. But, I would like some independent corroboration from other users in the Linux community. Could some of you perform the test yourself on this URL? An error will be readily apparent.

Requires Installation of Untrusted Packages

I am new to Debian (just used Gentoo until now), I run a little server for our company and clients. Unfortunately our hosting company switched us from a Gentoo system to a Debian Lenny box with Confixx and stopped maintaining it. So I will need to do the house keeping, which worries me a bit. Today I started and ran: aptitude update && aptitude safe-upgrade and got a huge list with packages to upgrade. Unfortunately, I am not confident, if I will break something upgrading (Confixx, apache) as I get the following warning message:
WARNING: untrusted versions of the following packages will be installed!
Untrusted packages could compromise your system's security.
You should only proceed with the installation if you are certain that this is what you want to do.
mysql-client mysql-server-5.1 mysql-client-5.1 mysql-common mysql-server-core-5.1 mysql-server libmysqlclient16
Do you want to ignore this warning and proceed anyway?
Is it safe to ignore it and upgrade the needed packages?
I was recently connecting securely to the website where I have my mail account, and I connected through Tor. When doing so firefox presents me with the screen saying that the connection is untrusted and it can't verify the certificate. So I cancelled. I'm using torbutton and I turned torbutton to off and connected again with no problem. Then with torbutton on again, same thing (untrusted).
Is it possible the exit node I was going through is doing a man in the middle attack? However later when connecting through tor I did NOT get the warning about the site being untrusted. I really don't know what exit node I was using when I got the certificate warning and what exit node I was using when I did not recieve the warning. I don't know how long I stay on the same node or how/when it changes.
I have to deploy a server to some customers that should not be given access to the server itself. I know that nothing is 100% secure but I've searched without finding a decent answer (maybe I googled for the wrong terms ?)I need some advice about encrypted filesystem. * The server must boot without asking for a passphrase (the server will be in a restricted access area so typing a password could take a while). I can't store the password for luks in an unencrypted file so it seems a loop to me. The only way out I can see is to store the passphrase in the boot binaries (better than nothing...) but this results in more work for me.* possibly the customer should not be able to move the hard disks to another pc, i.e. reading the passphrase from some unique hardware ID. This is risky but I could add a master passphrase to be used in case of hardware replacement
View 3 Replies View RelatedAt school, the shop I work in has machines that run windows xp and cannot be updated to the latest SP (consider these machines "B"). This means that they are quarantined whenever connected to the network. There are also workstations that we would like to be able to connect to "B" for the sole purpose of dropping a file into a directory. These machines we will call "A" and are considered trusted.
I have No control of the school's network. I have a spare PC with two NICs as well as a 5 port switch. My thought was to use the spare PC as a gateway/router/VPN and setup an isolated "network b" consisting of all the untrusted systems. Disallow all traffic other than the VPN connection. Connect via vpn from the 4ish trusted workstations "A" to Network B. I could use mac filtering (I think) to accomplish this and disallow any computer not specifically authorized, thereby isolating the untrusted computers completely.

I installed a system yesterday without any problems, so I wonder if there's a recent problem with the mirrors I'm using. My /target/etc/apt/sources.list contains:

So it looks like either the UK mirror or security.debian.org.
