Ubuntu :: Need To Decrypt QR Barcode : Can't Run Software Installed Via Repo / Resolve It?
Jul 25, 2010
I have a Qr barcode to decrypt and to do this I installed from the official ubuntu repo the software needed.
The problem is this: I can't see the software in any menu.
From shell I know how to create a Qr barcode, but I'm unable to decrypt one.
Someone have any idea about how to do it from CLI or in any other way?
I had added a repo from this site: [URL]...now, i have removed the repo as i dont want to use the software anymore, but how do i make sure that i have removed everything on my pc installed from that repo?

I have installed a package on Centos 5.5, and need to find out the repository it came from, so I can enable the source rpms for that particular repository, and download the source, and rebuild the package. Is there some way using yum or rpm to find out which repo the installed package came from? I know Smart PM shows this info, but it has been hanging on Centos 5.5, for some strange reason, so that's not really an option for now.
I'm running 10.10LTS at present, I upgraded via the Upgrade Manager last night, Firefox 3.4 and D-bus stuff if I remember correctly. The system then gave the "restart now or later" buttons and I hit the "now" one. My system, an AMD 3800+ dual core job in an MSI mobo then shut down and, er... died. hitting the momentory action power switch gives an ocasional short noise but I have no power/fans or anything. It's a 480 Watt PSU with green leds and stuff I don't really need but the price was good, so I'm not convinced that it's dead... yet.
Is it possible for an upgrade to stuff the power-up circuitry? Maybe power management?
My next step is to swap the PSU to eliminate this as the "faulty" item. It leaves the Mobo, screwed CMOS and possibly the switch cabling/connector but it's all a bit suspicious. I'm basicially a hardware guy so that's the path I'm following. Unless the upgrade's written to somewhere it shouldn't?
I haven't had time to investigate further as I was dragged away shouting and screaming to a prior engagement by "she who must be obeyed".
Does anybody know of a database program that allows one to use a barcode scanning system? It would be like a library system, but used to track inventory. A library program can work though (we would just see checked out as sold or something like that).
I am trying to install Fedora12 on a usb hard-drive, the first problem I encountered was that the hard-drive would not boot stating "kernel panic: unable to create root device", this is just using the standard fedora 12 install and mostly clicking next (although I add my vista to the grub and tell grub to install to /dev/sdc which is the location of my usb hdd).
I have also tried livecdtousb (wont boot in stick and wont recognize removable hd as removable)
I have tried setting up disc encryption and installing with no LVM.
The drive has this same problem with ubuntu 9.10 however ubuntu 8.10 installs perfectly and I am guessing earlier versions of fedora will too. The problem is that I would like the kernel features of Fedora 12 (mainly modesetting) without this issue.
I have played about with grub and quite like disabling LVM and using the uuid of the drive to select the root partition, my boot partition has 500mb, I have a 2gb swap space 50gb ext4 root partition & 27gb fat32 partition code...
I have nine barcode scanners, each of whose input I want to send to a separate instantiation of a program I wrote. Each device shows up as /dev/hidraw_ (I'm using Ubuntu 10.4). The problem is that they all act as simple keyboard input, and I can't seem to redirect the output from one to a specific instance of my program. I've tried something like cat /dev/hidraw5 > ./myapp, and that doesn't work. I've tried actually opening the device in my program using open("/dev/hidraw5"), and it returns success, but subsequent reads don't do anything, and the scanner output is just printed to the console.
i'm attempting to know and understand fedora more and i will spend probably the next month pouring through all the forums and documents to answer more of my own questions. but there's quite a bit here, so i'd thought i'd ask some noob questions to get me started a little.
ive installed fedora 14 64bit and chosen only kde as the desktop. i selected an extra 2 repos besides the default, fedora 14 -x86_64 and fedora 14-x86_64 -updates. i believe this kernel is installed: 2.6.35.11-83
1. i can only see the 2 extra repo's as being "checked" in kpackagekit, shouldn't i see the default repo also ?
2. i dont have an applet in the system tray indicating the system is up to date, does fedora have this by default ? also after a clean install i ran yum check-update and yum update but the message sayes: "no packages marked for update". i'm not sure if the system is auto-updated during install or not, but with other distros iv tried there is always atleast a few updates needing to be done after install.
3. is kpackagekit the fedora gui package manager ? i dont see any others.
4. i want to upgrade to nvidia drivers, but i think i am missing a non-free repo or something. when i enter: yum install kmod-nvidia xorg-x11-drv-nvidia-libs.i686 xorg-x11-drv-nvidia-libs.x86_64 i get messages stating "no package" i get the same message with yum install nvidia-settings.i also tried this: LANG=C yum --enablerepo=rpmfusion-nonfree info akmod-nvidia but it sayes repo not found.

If I disable the repo-non-oss repository the update works fine. The URL I have for the repo-non-oss repository is:
Index of /distribution/11.0/repo/non-oss
This has been going on for over a week. Do I need to use a different URL for the non-oss repository? I live in New York, United States.
I'm having trouble decrypting a GNU key from LaunchPad.I have followed what the doc's say about it but it doesn't work for me.My Thunderbird can't read it also. I have used the plug-in but I have hotmail.
I am trying to decrypt wmv files in Ubuntu. I have installed the w32codecs and I am able to decrypt dvds. I also have access to medibuntu, but I cannot tell which package(s) at that repository are helpful (if any). The tunebite converter only appears to work on Windows.
I wasn't paying proper attention when adding a repo to yast and need to find the file were the info is saved to delete this. The problem is that whenever i use yast it comes up with an error code saying that it can't find the data for the 'problem' repo. Have tried zypper rm but that comes up with a similar error advising that the data is in a format that was not expected. My thinking is to track the file were the yast repo source details are saved, delete this and then just add the repos that i use back.
I chose the option to encrypt my home folder during installation, but I don't want it encrypted anymore since that makes it impossible to access any files in my home folder unless I'm logged in as that user.
I'm really hoping to avoid reinstalling from scratch just to fix this. Anyone know how to do it?
lets say I install Ubuntu 10.10 on my laptop. I check the box that says encrypt my home directory, and my password is a randomly generated 10 character password using uppercase and lowercase letters and numbers. The next day my laptop gets stolen or something. How hard would it be for someone to decrypt the home directory if that were the goal?
All whas encrypted thrue the setup. When i log back in i check places/removeable media/25.1 GB Encrypted data. and when i press i type my password and hit enter, but it wont decrypt?
I have disk on desktop, bt i cant do anything whit it?
I need to be able to decrypt data, like simple text files, that have been encrypted and base64 encoded with my public key.I need to use openssl so i do:
and i get exactly the same data as before the command was run. Am i right in thinking that i need to decode before decrypting? I tried decrypting, before i realized that i had to decode first,using this command:
I was wondering if any free, small, portable, cross platform programme exists for encrypting/decrpyitng simple txt files?
I know a couple of small ones for windows systems (nosee, dscrypt) but i wonder if there is any i could use on both linux and windows OS. the idea is to be able to carry it on USB key and the programme (or probably there will have to be 2 versions of it) would run either on windows or linux os and i could decrypt and encrypt the file if i needed to. no matter on what system i plug the USB key to.
I'm trying to install debian on a encrypted partition with LUKS and LVM. I've found a good tutorial for ubuntu (here but it's in french). The idea is to create a sda1 partition for /boot and create a sda2 partition which is encrypted with luks ("cryptsetup -c aes-xts-plain -s 512 luksFormat /dev/sda2") and on this encrypted partition, I use LVM to divide it in several different partitions (root, swap, home,...).
I can do it all with the debian live cd but once it's done I need to install debian. The problem is that with the basic install cd (I use netinstall), I cannot decrypt the partition for the installation (or if I can how ?)And with the live cd, I didn't find any option to do that.
I want to be able to encrypt files on my netbook with Ubuntu 9.04 UNR and on my MacBook (Mac OS 10.6.2) and be able to exchange them and decrypt them on the other platform.The Ubuntu command Edit>Encrypt is so easy to use but works only on the netbook. I haven't, thus far, found a program to open them on the Mac or to create an encrypted file on the Mac that I can open on the netbook.
Is there a way for my home folder to not be automatically mounted when i log in? And for that matter a way to change the password from my log in password to something else?
