Default Keyring Password Problem

I found an old laptop that has centos 5.5 installed. I reset the root password, but I need to reset the gui password. Is there a way to view this password or reset it? I have not worked with Linux over 5 years and am rusty on all the commands

I'm running kali linux. I'm having troubles installing pretty much anything, because when I add any ppa using the add-apt-repository command, I get an error message. I'll use simple screen recorder as an example

add-apt-repository ppa:maarten-baert/simplescreenrecorder

maarten-baert/simplescreenrecorder
Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret-keyring /tmp/tmp.EQM7zzCyye --trustdb-name /etc/apt//trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-jessie-automatic.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-jessie-security-automatic.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-jessie-stable.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-squeeze-automatic.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-squeeze-stable.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-wheezy-automatic.gpg --keyring /etc/apt/trusted.gpg.d//debian-archive-wheezy-stable.gpg --keyring /etc/apt/trusted.gpg.d//kali-archive-keyring.gpg --keyserver keyserver.ubuntu.com

Can someone please tell me what is going on? I have never been able to add a ppa before using kali linux.

Hi everybody,

I used to be a Linux developer, but I have not used Linux or anything UNIX-like for a long time (more than 10 years). I had it installed by someone else and assumed that the root password is not set. Turned out - it has been. I can logged in as "owner" because I have guessed the password ("password") but no such luck with root. Can anything (other than reinstallation) be done? Is there some default password that root gets at installation that someone at this forum knows? Any other suggestions?

Thank you in advance.

I just booted my PC in Vector Linux 7.0 Standard Live Edition. It is a bootable version of Linux that requires no installation. I am currently booting of a DVD-RW. The problem I am running into is the default password for root has already been set. It didn't prompt me to create a user or password at any point. In fact the first time I booted it all that happened was the Operating System loaded up. All I have done since them is run a portable netbeans and try to access the hard drive. When I tried to access the hard drive I got the following error.

Authentication is required to mount the device
An application is attempting to perform an action that requires privileges. Authentication as the super user is required to perform this action.
Password for root: _______???______

I found a few password suggestions on forms like root and vector, but these didn't work. If you would like to experiment with the OS burn it to DVD. See if you can figure out the solution to the problem. Here is the download link: http://vectorlinux.com/downloads

Hi

I unfortunately can not remember my supa user password for Ubuntu linux on my Odroid U3.

Being new to linux I am lost as to how to restore or reset the password.

Any help offered will be really appreciated.

Hi
When i tried to change the password for a particular user as a root by using usermod command I didn't see any error at that time.But later when I tried to login again it is not accepting the new password as well as old password.Why its happening?Any help....

Hi, I forgot my password so went into root to change it.

From grub menu, Ubuntu : advanced options : ubuntu recovery : network : root

input passwd then typed in a new password and re-entered password. rebooted.

Tried to uninstall Firefox from software centre but the new password was not accepted for authentication.

Could anyone advise what the problem could be or suggest what I may have done wrong. The password appeared to be accepted ok in root. Thanks

is there a way via terminal to reset the username and password for my router?
i have recently started working with the terminal and in order to use ssh im going to need to download some software and enter the username and password for the router which i havent a clue what it is. im not sure i ever set the username and password on it????

if i could re make the username and password for my router i would then be able to get this ssh working.

or is this not possible?

I need to be able to create new user accounts and make sure they're forced to reset their password upon first login, also if they don't log in within 4 days of the account creation their account must automatically lock. How do I accomplish this?
