• sudo does not work in GUI after upgrade to 13.10

  - by Radim

  On 2 completely different machines I have the same problem after upgrading from 13.04 to 13.10: All programs/task requiering sudo permissions (software updater, starting synaptic, installing programs, shutdown) do not start / execute. No gksu (or other) window comes up. Synaptic never shows, software updater pops up with a "you are not allowed to perform this action" message. All programs / task work when started from terminal with sudo, like "sudo synaptics" asks for my password, starts and works as expected. I am in the admin group which is liked in sudoers config (verified with visudo and getent group admin). Some link from GUI to gksu (or similar) is broken. Please help! Radim

• Can't login to Ubuntu One

  - by Gabriel

  I uninstalled Ubuntu One about two months ago and now I re-installed it. I can still login with my account through the site (Ubuntu One) but the client keeps telling me "The authentication failed". If I try to use the Recover password option it also fails with telling me that my email address is not recognized (while I can use it with zero issues through the site) If I attempt to create a new account from the client, it also fails to load the captcha every time. Something is clearly broken here but I can't figure out what it is. Any ideas?

• Ubuntu doesn't start and I can't login

  - by Meph00

  My ubuntu 13.04 doesn't boot anymore. Eternal black screen. If I press ALT+CTRL+F1 I see that it's stucked on "Checking battery state [OK]." I'd like to try to go with sudo apt-get install gdm but I can't login on terminal tty2, tty3 etc. They correctly ask for my nickname, then they make me wait a lot, ask for password and make me wait again. After a lot of time (... a lot) the best I could achieve was visualizing "Documentantion https://help.ubuntu.com". I can never reach the point where I can give commands. Plus, during the long pauses, every 2 minutes it gives a messagge like this: INFO: task XXX blocked for more than 120 seconds. Any suggestion? Sorry for my bad english and thanks everyone for the attention.

  I'm developing a standalone application using java, I have a Login screen, wherein user enters his username and password. For each instance of the application, user have to enter his credentials. From a usability standpoint, I thought of keeping a remember me check Button. My question is, as I am not using any database, how do I persist the user details. I have some rough thoughts, storing them in a property file and retrieving. I think there may be better approaches than the one I had. Any Ideas and suggestions?

• Issues running alongside windows and connecting to wireless network

  - by user292247

  Okay so I'm trying to get started with ubuntu but I'm encountering a couple problems: When I boot up the CD and try to install, it does not recognize that I have windows 7 installed and just sees it as unallocated space so the only way I've been able to install it is by wiping the drive which was fine, but it'd be nice to be able to boot either. And secondly, I cannot figure out how to get wireless working. When I try to connect on the initial installation process it tells me to connect to my adapter and just asks for a password. I suspect it could be a driver issue but I wouldn't know where to find it. I have an AR9485 atheros adapter and am attempting to run ubuntu 14.04. Thanks

• Why won't Remmina connect to Windows 7 Remote Desktop?

  - by rfc1484

  I'm using Ubuntu and I'm trying to connect to another machine in a different network using remote desktop. In Windows7 I have made the following in order to activate remote desktop: I've gone to computer - properties - remote settings I've selected the option: "Allow connections from computers running any version of Remote Desktop I've opened "Windows Firewall with Advanced Security" In inbound rules I've enabled the rules for remote desktop (public and domain) I have also installed Remmina in the Ubuntu machine. For configuring it I did the following steps: Selected the RDP protocol In the server input I have written the Windows machine public IP. In username / password I have typed my login credentials (the same as my Windows admin account) But when I try to connect I get this error message: "Unable to connect to RDP server 89.130.251.160" If I ping my Windows7 machine, I have a correct response. Any suggestions?

• How to get KeePass to properly work with Chromium?

  - by Tom

  The two-channel auto-type obfuscation feature of KeePass doesn't work for me with Chromium (on Ubuntu 12.04 64 bits). However, it works just fine with Firefox. Dows anyone know how to fix this? Textboxes in web forms in Chromium seems to have something special that causes this feature to fail. Only some of the username/password characters are being auto-typed. This might be related to this: if I select an entry in KeePass and click "Copy User Name", I can paste it fine with Ctrl+V in any textbox in Firefox, but I can't on Chromium. However, text copied using Ctrl+C from a regular text file (say, from gedit), can be pasted fine on both browsers. What may be wrong? I wouldn't like to deactive this feature for all the entries in my keepass files as I use them on Windows too and they work just fine there (even on Google Chrome for Windows). This feature gives an appreciated extra security measure against spyware/keyloggers.

• Why is the superblock last mount time in the future?

  - by user69541

  Future time: Since installing Ubuntu 12.04, I regularly have to fun fsck and reset my clock because it shows a 'future time' : Err.Msg. "superblock last mount time is in the future by less than a day, probably due to hardware clock being incorrectly set." FIXED. According to what I have read, it looks like I'm in the right place to get an answer. Following are my feeble attempts to rectify this annoyance: mjh@mjh-desktop:~$ sudo service ntp start [sudo] password for mjh: ntp: unrecognized service mjh@mjh-desktop:~$ mjh@mjh-desktop:~$ sudo apt-get install update Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package update mjh@mjh-desktop:~$ sudo service ntp start ntp: unrecognized service mjh@mjh-desktop:~$ Suggestions?

• Can data classes contain methods for validation?

  - by Arturas M

  OK, say I have a data class for a user: public class User { private String firstName; private String lastName; private long personCode; private Date birthDate; private Gender gender; private String email; private String password; Now let's say I want to validate email, whether names are not empty, whether birth date is in normal range, etc. Can I put that validation method in this class together with data? Or should it be in UserManager which in my case handles the lists of these users?

• Creating a user called 'root'

  - by pnp

  I am creating Virtual Machines using the ubuntu-vm-builder. The syntax goes something like this: ubuntu-vm-builder kvm precise \ --domain newvm \ --dest newvm \ --arch i386 \ --hostname hostnameformyvm \ --mem 256 \ --user john \ --pass doe \ --ip 192.168.0.12 \ --mask 255.255.255.0 \ --net 192.168.0.0 \ --bcast 192.168.0.255 \ --gw 192.168.0.1 \ --dns 192.168.0.1 \ --mirror http://archive.localubuntumirror.net/ubuntu \ --components main,universe \ --addpkg acpid \ --addpkg vim \ --addpkg openssh-server \ --addpkg avahi-daemon \ --libvirt qemu:///system ; I need to enable the 'root' user account after creating each of my VMs (and supply a password for it). I was just wondering whether I can take this short-cut of supplying the username (--user) as root in this command itself. If I supply username as root to create my VMs, am I creating/enabling the root user, or just creating a user named as root? p.s.: any better ways to achieve my task are also welcome. But I don't want to manually meddle with each VM after its creation

• totally stuck trying to SSHing remote server

  - by user9609

  Hey guys, So i've been given access to ssh a server. I have the username/password, but server apparently requires a public key (now bear in mind that i am a noob in ssh). When I do: ssh -p 52 [email protected] terminal says Permission denied (publickey). So I went using ssh-keygen -t rsa and got myself the id_rsa and id_rsa.pub files in /root/.ssh. Chmoded /root/.ssh to 700 and /root/.ssh/* to 600. Tried sshing server.com again, same error. What am I missing? I've been given a Putty Pagant Key file (.ppk) by the SYSADMIN of server.com. Apparently, other users (all Windows) can connect using Putty Pagant.exe. Please help :)

• Why ~/.bash_profile is not getting sourced when opening a terminal in Ubuntu 11.04?

  - by Viriato

  Problem I have an Ubuntu 11.04 Virtual Machine and I wanted to set up my Java development environment. I did as follows sudo apt-get install openjdk-6-jdk Added the following entries to ~/.bash_profile export JAVA_HOME=/usr/lib/jvm/java-6-openjdk export PATH=$PATH:$JAVA_HOME/bin Save the changes and exit Open up a terminal again and typed the following echo $JAVA_HOME (blank) echo $PATH (displayed, but not the JAVA_HOME value) Nothing happened, like if the export of JAVA_HOME and it's addition to the PATH were never done. Solution I had to go to ~/.bashrc and add the following entry towards the end of file #Source bash_profile to set JAVA_HOME and add it to the PATH because for some reason is not being picked up . ~/.bash_profile Questions Why did I have to do that? I thought bash_profile, bash_login or profile in absence of those two get executed first before bashrc. Was in this case my terminal a non-login shell? If so, why when doing su after the terminal and putting the password it did not execute profile where I had also set the exports mentioned above?

• uswsusp won't hibernate with freeplane and some websites open

  - by Richard

  I installed uswsusp on my laptop to hibernate faster, which works most of the time, but whenever I have freeplane (and some websites in firefox...can't recall which ones but can probably find some) it fails. In order to hibernate, I have to resort to closing the offending program or webpage - but this kinda ruins the point of hibernating... It fails when I try sudo s2disk in a terminal with freeplane open, but strangely works with sudo s2ram --force. When it fails, it simply switches to the black screen with s2disk: Snapshotting system but then returns to the login screen. When I enter my password, the hibernating indicator continues flashing but goes back to the desktop I left when trying to hibernate. When it works, it works as expected from hibernate, shutdown and resume. I saw another thread discuss fglrx modules and to include it in MODULE="fglrx" in /etc/default/acpi-support, but that hasn't helped me. I'm using Ubuntu 11.10 with an ATI graphics card on an Acer Aspire 6920.

• Can't login to my XFCE environment from lxdm

  - by Noob

  I installed lxdm as my display manager because I heard its very lightweight. Now after installing it when I select my Desktop as Xfce session I am not able to login. Basically what happens is it waits for sometime and than reload the same login page. On the other hand if I select lxde as my Desktop I am able to login. So, what am I doing wrong here. The other problem I am facing with lxdm is it doesn't show my default user account. I have to select more and enter both my username and password to login into any session.
