When ever i use a "sudo" command, it returns "sudo: can't open /etc/sudoers: Permission denied".... HELP PLEASE
While using terminal, any commands with sudo returns the statement seen in the heading... I have only a basic idea of whats happening, so please try and make the solutions simple.. much appreciated
Are you being prompted for a password? Are you using the same password you sign in with? Try just entering sudo with:
sudo su -
It will ask you for a password and then give you a stern warning about acting as root, where you can really mess up your computer for good if you are not careful. If it won't change to the root account you have a permission problem or a credentials problem.

Sudo unable to open /etc/sudoers
Whenever I try to do anything at all with sudo on my fresh x86-64 Arch install, it prints out this error:
sudo: unable to open /etc/sudoers: Permission denied
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin
This is on a fresh Arch install from the core Image CD, packages initially installed from the CD and then upgraded with #pacman -Syu. I can edit sudoers just fine with visudo, and installing outdated versions of sudo produce the same error. File permissions on both /usr/bin/sudo and /etc/sudoers both look as they should be. Also, users and user groups don't seem to be an issue.

It's just probably something that happened while installing the core packages from the install CD that caused problems. As of now, I just reinstalled Arch on a new partition (this was a fairly fresh install) and it seems to work just fine. I was willing to continue to test the issue, but resizing the partition seems to have corrupted it somehow.

Sudo can't open /etc/sysinfo.conf mac os x lion
I have been trying to get locate to work for ages now (well not really, only since I upgraded to lion).
And I'm having no joy. I keep getting an su error when /usr/libexec/locate.updatedb is being called.
Terminal just throws this cool error "su: Sorry".
Console (syslog) shows this error
(pam_acct_mgmt: error in service module)
Which apparently means an error occured in a PAM module
I decided to run dtrace opensnoop to find out what files were being opened and what was going wrong.
Mind you that I am not versed in Dtrace, this is one of my first uses.
This is what I get when I run "sudo /usr/libexec/locate.updatedb" whilst running "sudo opensnoop -x -n sudo -e":
UID

/etc/sysinfo.conf does not exist on my system.
This might be the cullprit, but I'm not sure.
I have been getting the very "helpfull" tip to just use mdfind.
Not being able to use locate isn't the end of the world for me, it just bugs the **** out of me that it doesn't work anymore.
I can't shake the feeling that I don't know what else is broken.I fixed the issue by doing a clean install of Lion.
Now locate works as expected.
Incidentally, when I installed Xcode on my upgraded version of Lion I had the same problem that many other people had which was that the installer window (the one with the progress bar) got stuck at 99% even though Xcode finished installing.
I did not have this issue with the clean install Lion... hmm go figure. -
I uploaded music in the match and when i want to play it in my phone, some of the tracks appear blocked (blanked) and a few not. When I'm connected in a wi fi spot, I can play all of the tracks. Help please.
Hi,
You need a wifi connection to stream. Previously played tracks appear in a temporary cache which allows them to be played again when yOu have no wifi..
You can either predownload selected tracks or use cellular data.

I have an audio problem that when ever I use my Firefox web browser it makes a sharp audible sound similar to a video game gun shot sound effect when ever I go into a new web page? I change to a new site or page a page on a site, I get an audible gunshot ping trpe sound? It happens almost every time. Its very annoying and is driving me nuts???
Any body out there had this happen also or know how to diagnose and fix this type of problem? I would hate to have to delete my whole Firefox program and have to start over again. If that is the case I will probably just scrap it and go on to try Google Chrome instead. I already have GC partially set up. I really have liked Firefox up to this point. I know add ons can cause problems at times but I haven't added anything new lately and this just started happening?Hi,

Suddenly with version 9 and 10 i cant use the shortcut command of ctrl+shift+t to open the most recently closed tab. a feature used several times a day, previously. This is very Frustrating to me, i have tried looking up a tool keyconfig 20110522 and looked that it says that ctrl+shift+t is the right command, but i still cant use it WHY oh WHY?? if i could get some help figuring this out it would be so awesome, cause i love Firefox, been using it almost daily for the last 10 or so years and i don't intend to switch soon.

I am trying to empty my trash but it wouldn't . so I ran this command sudo rm -rf ~/.Trash/* in the terminal
I got an error message
"sudo: unable to stat /etc/sudoers: No such file or directory
sudo: no valid sudoers sources found, quitting"
does anyone have a clue? thanksFirst, never use the shell (Terminal) to empty the Trash. It's dangerous and unnecessary, and it usually doesn't work.
A necessary system file is missing. If you know how that happened, restore it from a backup. Otherwise, see below.
If you don't already have a current backup, back up all data, then reinstall the OS.* You don't need to erase the startup volume, and you won't need the backup unless something goes wrong. If the system was upgraded from an older version of OS X, you may need the Apple ID and password you used.
If you use FileVault 2, then before running the Installer you must launch Disk Utility and select the icon of the FileVault startup volume ("Macintosh HD," unless you gave it a different name.) It will be nested below another icon with the same name. Click the Unlock button in the toolbar and enter your login password when prompted. Then quit Disk Utility to be returned to the main Recovery screen.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
If you installed the Java runtime distributed by Apple and still need it, you'll have to reinstall it. The same goes for Xcode. All other data will be preserved.
*The linked support article refers to OS X 10.10 ("Yosemite"), but the procedure is the same for OS X 10.7 ("Lion") and later. -

I just got a notice to update my firefox to 4.0 and when I downloaded the new software it indicated: that I can't open the application "Firefox" because it is not supported on this architecture. Any ideas about what might be wrong and how to fix it?
Firefox 4 requires at least OS X 10.5 and an Intel Mac. There is a third party version of Firefox 4 that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox
If you prefer, you can get the latest version of Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html -
