Ubuntu :: Can't Run "sudo Firefox" After Installing Security Updates
Jun 1, 2011
After installing a number of security updates that were listed in the update manager, I can no longer run the "sudo firefox" command.
I got the error message:No protocol specified cannot open display
I found this thread: [url]
Through which I found that I am able to run "sudo firefox" after running:
HTML Code:
I realize this doesn't give you a lot to go on.
Question: Is there a way to view which updates were last installed on my system?

With an Ubuntu 10.10 upgraded from 10.04, under Software Sources, Updates, there is a radio button marked "Install security updates without confirmation." I have this radio button marked, but still get "Important security updates" almost daily in my update manager. I don't remember this feature actually ever working.

Does anyone know when we'll see Firefox 3.0.19 packaged for 8.04 LTS? I'm still stuck at 3.0.18. And what will happen after this? My understanding is that after .19 Mozilla is dropping support for FF 3.0.
Upgrade policies not withstanding, I find it rather annoying when an "LTS" release doesn't keep up with the most security-critical package in the distro, the browser. 8.04 LTS should have moved to FF 3.5+ a *long* time ago. Now it seems it will be forced to do so or else just forget about browser updates for the last year of 8.04?
I know I can install the current Firefox with ubuntuzilla, I just keep wishing Ubuntu would do it for me.

In installing Firefox with sudo apt-get install firefox I don't get Firefox version 5. It seems odd that with Firefox being the main browser included with Ubuntu we don't get the greatest. What is the location of Firefox in Ubuntu, so I can install it with the tar command like on Slackware? Also, anyone know an operand to make tar overwrite files in Ubuntu so I don't have to rm them first, or is this just enhanced security?

After I got the OS up and running (v9.10), I was prompted to download and install some updates. The download is complete, but when I try to install the updates, I receive the following message. What should I do?
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
E: _cache->open() failed, please report.

A day ago I finally got around to upgrading the PackageKit installation that had been sitting for a week and a half, so I found a new upgrade for sudo available - the one that gives the sudoreplay command, I forget which version number it is exactly. When I try to use the sudo command I get this notice in my terminal:Code:Can't open /var/db/sudo/me/1: Permission deniedI didn't get it before. What do I have to do to make it open? I'm using SELinux in enforcing mode if that helps.

For some reason Update Manager is not installing updates as of yesterday.I have it set to check daily and notify if updates are available. It has been working without issues for well over a year now.
Update Manager tells me updates are available and presents the list of security, recommended, and other updates. All are selected to update, but when I select Install Updates in Update Manager it returns with a Reading Package Information window overlaid on the main Update Manager window - building dependency tree then reading state information and dumps me back to the main Update Manager window without performing any update actions.

So, it is my understanding that Ubuntu's automatic updates do not install ANY updates that are not "important security updates." For example, it did not upgrade me to Firefox 4 automatically; I had to do it myself (Don't all new browser versions usually contain new security features/patches? Oh well...That is a separate question entirely).
ANYWAY, is there some way to get the latest stable versions of all of my open-source software automatically (or at least all at once, on command), instead of just security updates? It seems silly to have to install new versions for every program manually.
Also, related/side question: Now that I have installed Firefox 4 myself (via apt-get by adding the mozilla-stable PPA), will I stop getting security updates for Firefox through the standard Ubuntu update manager?
Actually, a really thorough explanation of the whole automatic update system (or a link to one) would be great too.

I am new to fedora (been using debian based distro's for the longest time). With the new release I decided to give FC13 (The kde 64 bit spin) a try. I told it to wipe my entire hdd and encrypt the partitions. The partition manager made a few LVM partitions which I assume are encrypted.
The problem I am having is that if I attempt to use an application that would normally need root access to run, I am not prompted to enter my root password. Instead, I am required to logout and log back in as root. Is there a way to make it so that FC13 will prompt me to enter in my root password so I do not need to log in and out? Or is there something Different I should have done during the install process? Also, what is the terminal equivalent of "sudo" in fedora, or is it still sudo/KDEsudo
I also have not used SE Linux before. Do I need to manually enforce the permissions for my applications and generate my own profiles for it, or is that done automatically?

So yesterday I receive a copy of the SANS @RISK security vulnerability newsletter, and, lo and behold, Mozilla's Firefox and Thunderbird are on it yet again. (Yeah, I know, shocking, isn't it?)So I quickly check what versions I have installed. Yup: Vulnerable.I check whether updates are available.These are pretty serious "remote code execution" vulnerabilities and the status is "vendor confirmed, updates available." So why isn't my 9.10 desktop's update manager telling me updates are available?

I'm new to server admin, so my question is based on what may be a bad assumption. With a server, my assumption is "if it ain't broke, don't fix it". In other words, I'm not really interested in upgrading the software to the latest and greatest if I already have stuff working on the server.
However, the one place where I DO want to constantly have upgrades is for security patches. How do I apply security updates to Ubuntu Server... and ONLY security updates?

I use Ubuntu 10.04.1. When i write to terminal "sudo firefox" it opens the firefox with the default users config settings. But when i write "sudo nautilus" it open the nautilus with new config settings. This means there is a problem on my system ? (when i open the firefox with "gksudo", it is using as new user (root user's) config files but nautilus is opening with the root user's files also with "sudo").

I have a win7 laptop and installed a dual-boot ubuntu 10.10. I'm using firefox & thunderbird, shared between windows and ubuntu (default profiles are on a fat32 disk that is shared between the two OSs). I can mount the fat32 disk as usual, but I can't get firefox OR thunderbird to start unless I start them from a terminal using 'sudo'. This is kinda strange. I used to do this all the time and never had a problem before.
I installed firefox, then did:
cd /etc/firefox
sudo firefox -P
in the profile manager, I set the profile file etc, but when I open firefox without doing 'sudo firefox', it hangs up and cannot find the profile. Why do I have to use 'sudo' to open firefox or thunderbird?
It works fine on my other laptop, but I've deleted & reinstalled ubuntu 3 times on this laptop and still have the same problem.

I just migrated into Ubuntu 9.10 from Windows and moved my mail profiles and also my bookmarks to Thunderbird and Firefox.
I can't see the Mail profiles and messages unless I run "sudo thunderbird" and I can't save or edit bookmarks in Firefox unless I run "sudo firefox".
Probably it's best if I don't run Firefox or Thunderbird as root, eh?
I've tried changing the file permissions for bookmarks.html, but no luck. And haven't even tried to tackle the Thunderbird issue yet.

I sudo apt-get removed Firefox from my system in favor of Google Chrome. However, Ubuntu still prompts me to upgrade Firefox. How do I stop that? Also, whenever I click on HTML files, Firefox is still the one that loads by default. How can that be if I've sudo apt-get removed it? And Firefox is still in my Applications->Internet menu... So, was my sudo apt-get remove successful?

Certain commands like:
fdisk -l
nmap -sT 192.168.0.1/24
iftop
require administrator privileges to run. A while ago i read a post(forgot where i read it) about being able to let a user run these commands in a script (that contains the desired command) created by the administrator/root without the user having to do a sudo and entering a password. Does anyone know how i can go about doing this?

I've enabled root under Ubuntu (i know frowned upon), I'd like to change the default behaviour of sudo so that rather than requesting my password (the password I logon with), it requires the root password.
Have searched the forums but can't find the answer.

At the terminal prompt, I can't login using su nor sudo. I can only login as root at the dialog level. How do I correct this?

I am using Ubuntu 10.04-alternate-amd64 for full disk encryption. After getting my updates which i get as soon as they are released. I am getting the issue temp root (sudo) password is not being revoked. After using any app that requires the use of sudo the permission for it does not get removed like it normally does.
I have tried logging out then back in, which usually removes the permission, this no longer works, also tried waiting and even after 1 hour permission still there. The only work around I have found is to use the terminal to execute the required programs then after closing terminal the temp permission is now removed like it should be. This issue has effected all of my systems and a friend of mine as well, (friend uses same distro).
To replicate issue:
1) Boot system.
2) Login.
3) Check for updates or any other app that uses root permission.
4) Logout
5) Login
6) Repeat step 3
7) App will not ask for permission it will use root permission automatically.

When I access a remote Natty client using VNC I cannot use the sudo command in a terminal. In fact, the terminal closes itself as soon as I type the sequence sud. Even su d. Or su d.
Sua, su a, su c, su e do not cause the terminal to close itself.
This appears to be some sort of new security "feature".
How do I "work around" it?
[edit]
I'd better elaborate.
I have a remote Natty running 11.04 64-bit desktop version. I have installed tightvncserver on it. I log in on 5901 from a Ubuntu 10.04 64-bit desktop using vinagre. The desktop works fine except when I open a terminal in it and type sud. As soon as I type the d the terminal vanishes. This appears to be a deliberate feature. I also log in to other clients that run 10.04 and this does not happen. I have run Mint 11 in VirtualBox on my local machine and created the same remote desktop and viewed it from mint 11 itself. Same thing happens.
It seems to me that 11.04 has been modified to kill a terminal that is part of a VNC display when sud are typed.
how to remotely administer a 11.04 desktop?

I do a lot of testing and developing on an Ubuntu machine at my university, and I don't have sudo access to the machine. It hasn't been a problem so far because the tools I've needed have been installed.
However, I have to build OpenCV, which has a lot of dependencies, some of which (notably, libbz2-dev) aren't installed.
I have access to localtmp on the local drive, and of course my own home folder (which is on NFS). Is there a way for me to install a local version of the tools I need using apt-get without sudo access? If not, is there another way to install them? I've been using CMAKE_INSTALL_PREFIX=/localtmp for some builds, but I'm not sure if this is the way to go, or if there is a better way.
tl;dr Is there a way to install applications locally without the ability to sudo?

In a rage of anger against VI I decided to open my firewall config file in gedit, made some changes and was then confronted by the fact that it was read only. I decided to change the permissions for the whole of the /etc folder with:
Code:
sudo chmod 777 /etc/*
This also changed /etc/sudoers so that now whenever I try to use sudo I get the error:
sudo: /etc/sudoers is 0777, should be 0440
segmentation fault
I cannot change it back to 440 because I need sudo to do that.
