Here's couple of suggestions you could try through either command line or grub -> Advanced Options for Ubuntu -> recovery shell (just remember to remount your system with sudo mount -o rw,remount / once you get there): Change permissions and ownership on .Xauthority file in your home folder. Refer to this for more info. In fact, check permissions on all ...

I suggest the following: Format the USB as you would normally do Encrypt the valuable files with cross-platform encryption software Put the encryption software on the usb stick together with the encrypted files. Now you can decrypt the files everywhere. For a list of encryption software: http://arstechnica.com/civis/viewtopic.php?t=1245367

This isn't the greatest fix.. but it worked. I just changed my password to something else. I noticed that one of the characters that I was using required being hit twice to register. This was only happening in the GUI. So I changed my password to not have that character and BINGO BANGO all fixed up.

First of all, if I remember correctly you have to check a box to install Ubuntu with an encrypted home directory, but I could be wrong. It certainly looks like it's encrypted. Secondly, the bad news: if you encrypted the home directory at boot, it doesn't use your account password, but a separate pass phrase. After you first booted a pop up comes up with ...

I plugged a monitor into the Ubuntu Server (it runs the Desktop version of Ubuntu 14, I believe) and upon logging in saw a message asking me to create a passphrase. I clicked on it and hit enter (for a blank passphrase). After that, I rebooted and password-less SSH logins seemed to work again. Before I mark this as complete, I will give this a few days of ...

to pinpoint the source of the problem, try to setup passwordless login for localhost on the server. This way, you deal with only one machine, the server. If it does work, the problem is caused by the client(s); if it doesn't, you'll have to figure out what's wrong with the server itself

This answer is based on an edit by the user to their own question. They should still answer when they can. Run an e2fsck -v /dev/device (replace /dev/device with the actual device path), and it can probably fix the issue.

You don't have to enter your password for everything. Either your installation is severely broken somehow, or (more likely) you're not using it correctly. Consider running ls in the terminal. You don't need your password for this. Do you always run it as sudo ls? Don't do this. If running ls without sudo fails, paste the result of running sudo ls -l /bin/ls ...

This command should do it: sudo chmod +s /usr/lib/policykit-1/polkit-agent-helper-1 I had this problem when I moronically changed the owner of /usr/lib recursively.

Linux and other UNIX-like operating systems handle permissions very tightly. If you launch applications from your terminal constantly, you can switch your permissions to superuser with this command: sudo su Note that this shouldn't be used as a be-all-end-all command. Software launched with root permissions can alter your system without asking for additional ...

If 'ashot' is your root account, don't call 'sudo passwd'. I've been doing that for the past few months and it wouldn't change my password. To change my password, I had to call 'passwd' without 'sudo'. Otherwise, the password modification is not taken account of.

This doesn't exactly answer the question, but it is another approach to the issue. A couple of versions of Kubuntu ago, I couldn't figure out how to turn this off either. Since I was kind of tired of screensavers anyway, I just turned the screen saving to start after an hour when power is plugged into my notebook (so it wouldn't come on while watching ...

had the same problem today and found your thread^^, so I started myself to solve the problem. I did the same as you did, except I used the conf file from the phone and put the psk in.

A group called PrivacyIdea have created a little package to add a HMAC-SHA1 challenge-response routine to the initramfs, which means that Ubuntu can query you for a challenge to pass to the Yubikey and then use the response to unlock the LUKS volume. For the most part, I'm following these instructions, with some added comments. The process is actually very ...

sudo asks for your password by default. It is not recommended, but you may bypass passwords for users/groups for all, or limited commands, if you chose to do so. Here is why sudo asks for a password by default: Linux is a multi-user system, and the easiest way to see this is to look at the root user, vs your own user. Major system-critical components are ...

Your account is member of the wheel/sudo group which allows you to perform super user commands, but it's not an "administrative" account like root. It is possible to use your root account to log on, removing the need to sudo. However, that practice is discouraged since it would expose the system to serious threats.

The user you are logged in as does not have all of the abilities necessary to perform all commands, this is to protect the system from accidental or intentional damage. Normally root and your username will have different passwords and only the system administrator will know the root password. It is a little different on a 1 user system where your username ...

It's in the nature of sudo to require typing in the password at login and after the password cache expired. If you keep your sudo password in an unencrypted text file (and even in an encrypted it's a bad idea) and want to manage it with kdewallet you don't have to worry about sudo -i because it's a much more secure alternative for your use case. Ah, and ...

This is normal - Ubuntu has this out of the box. What you can do, is restrict access to the actual command that allows you editing network settings, the nm-connnection-editor. Open terminal with Ctrl + alt + T, and enter the following commands: 1) ls -l $(sudo which nm-connection-editor) ; This will show current permissions for the nm-connection-editor ...

This seems to be a legitimate bug in lightdm, the program that manages the lock screen on Ubuntu 14.04 and later. I was able to reproduce this issue in Ubuntu 14.04.2. I've filed a bug report with the lightdm project, you can find it here. Make sure to comment on the bug report if you've experienced this issue! The workaround (as first mentioned by user ...

I managed to solve the problem. First I tried the suggestions in the comments to no avail. After a bit of searching of "Die Systemrichtlinien verhindern das Bearbeiten von Netzwerkeinstellungen für alle Benutzer" I found a Launchpad entry connected to this problem: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1045972 I created a file ...

do you have any information on the the laptop that you wish to preserve/save? if you don't, best thing to do would be to reinstall. This way, you will get to know a little more about Ubuntu/linux and I can assure you, it is not hard at all! Installing Ubuntu these days is very easy. try pressing the shift key repeatedly instead of holding-it. if the ...

In your gui login screen, on the top right corner close to network symbol, there is a square symbol with your current keyboard layout.

I'm not sure how long you've had this OS running, but if it's a new install why not just Nuke and Pave ? Reinstall your OS and you can have whatever password you want.

It is normal behavior for passwd to not show your password or even placeholders for characters (as is done in many apps including web browsers) because if someone knew the number of characters in your password it would be significantly faster to brute force. So just type away then press enter.

I had this problem too and while it still exists for me I have identified a workaround that enables my system to boot. My issue was to do with cryptsetup not accepting my password. This prevents me for booting and fixing system issues. Turns out that my password included a special character '@' as in P@ssword. At the prompt pressing RIGHT SHIFT and key 2 ...
