Red Hat / Fedora :: PNG Backend Error While Installing Cairo-1.6.0 - Requested PNG Backend Could Not Be Enabled

Nov 29, 2010

I want to install GTK+. I see there are also numerous dependencies, which i've been slowly tackling, and the Cairo package has been particularly difficult. It claims the following upon ./configure --prefix=/usr configure: WARNING: Could not find libpng in the pkg-config search path checking whether cairo's PNG backend could be enabled... no configure: error: requested PNG backend could not be enabled I've done some searching and found that libpng.pc is in my /usr/lib/pkgconfig/ directory and that the following commands don't do the trick:

Fedora :: Software Update Error - Failed To Initialize The Packaging Backend

Mar 15, 2010

From the GUI, software update gives the error "Failed to Initialize - Failed to initialize the packaging backend. This may occur if other packaging tools are being used simultaneously." In the more details, "There are unfinished transactions remaining.

I run a terminal, switch to root and do as it tells me. It returns saying that there are no unfinished transactions. I've run it several times with the same result. Then I run "yum clean all" and "yum upgrade." The upgrade processes runs and reports "there are unfinished transactions..." However, the upgrade process still completes. Basically it is now a severe annoyance, but the system does seem to upgrade. I just cannot figure out why there are somehow unfinished transactions that I cannot get rid of. I tried reinitializing the rpm database - no luck. How can I somehow reset yum?

Debian :: Install Not Supported By Backend

Aug 14, 2015

I am new to Debian Wheezy and I can't install anything. Ever time I try to install a .deb file I get the message saying that installation is not supported by backend. Also I'm unable to install from the terminal; it always says something like "path not found" or "file doesn't exist" (I'm on my phone so I don't have an exact error detail). Everything I've read tells me to install something to fix the problem but I can't install them due to the same error.

Ubuntu :: 100 Percent CPU (What Is Backend Under All Processes)

Apr 30, 2010

I've just installed the Netbook Edition of Lucid on my MacBook, and it works great, with two issues:
First, each time I start, the computer is extraordinarily laggy (pretty much unusable), until I run System Testing for video, and go through the whole process. Then it seems to work great. Also, I'm having a 100% CPU issue, which switches between my two CPUs. There was nothing under "my processes" that showed any kind of heavy use. But, under "all processes" was something called Backend. I killed the process and now everything seems to be working just fine.

Fedora :: Failed To Initialize Packaging Backend

Mar 16, 2010

Recently I started getting pop-up saying:

Failed to initialize
Failed to initialize packaging backend
This may occur if other packaging tools are being used simultaneously.
under more details i get:

There are unfinished transactions remaining. Please run yum-complete-transaction as root. I get to terminal, and as a root I try yum-complete-transaction, but it just says there are no unfinished transactions left. I tried to update thru yum, but this is what I get:

# yum update
Loaded plugins: fastestmirror, presto, refresh-packagekit
Determining fastest mirrors .....

After lots of googling, I tried:
"yum clean all",
"rm -f /var/lib/rpm/__db*" + "rpm -vv --rebuilddb" + "yum clean all",

Everything else is working well, and I am able to update with "--skip-broken", but I keep getting this pop-ups. I use fedora 12.

Fedora :: KPackageKit - Failed To Initialize Backend?

Jun 16, 2010

Since Livna went down, I've been having having problems with KPackagekit. I disabled the Libna repo by setting enabled=0 in /etc/yum.repos.d/livna.repo, and have been able to update with Yum.KPackageKit fails on me now with the message "Failed to initialize backend. This may occur if other packaging tools are used simultaneously."Then it fails to finish, which causes me to reboot before I can use Yum successfully.Under Settings, I see no indication that it knows where the repositories are, and no way to add repos.

OpenSUSE :: Why Is Zypp-backend Dropped In Kupdateapplet 0.9.11

Mar 24, 2010

in KDE:Factory:Desktop you can find a new version of kupdateapplet. In the changes you can find the following:

- dropped zypp plugin (bnc: 590192)
- V 0.9.11

I have no access to 590192 in bugzilla, so can anybody tell me why the only real working backend is dropped? The PackageKit-Backend is not showing the updates from 3rd-party-repositories (packman or obs). Is there any possibility to get back the working 0.9.10?

Ubuntu :: Partitioning The System Drive For The Backend?

Apr 27, 2010

Here is my learning curve or what I would like to try. 1. Install Ubuntu on computer with following hardware:ASUS M3A7-EM AM2+ CPU, looking for a 45w one 780G/SB700, if the onboard video gives me grief I will install a nVidia 2gb DDR2 RAM 320gb or 500gb system drive, nothing smaller in the cupboard.

2. I want to install Mybuntu backend on this computer as part of a media sharing system. I have several PVR cards and it will be trial and error to see what works. I have a 1.5tb drive for media storage.

3.I have several old laptops to experiment with as frontends, I also want to install Mythbuntu and Kubuntu on one these to compare KDE and Gnome. At least two of the laptops have wireless so it will be easy to network.

Ubuntu Servers :: MythTV (master Backend) 0.24.1 On 10.04?

Aug 12, 2011

I had a dedicated HTPC box running Mythbuntu 11.04 (MythTV 0.24.1, I believe) that was both a master backend and frontend. I was also running a separate box (server 10.04) as a file server, print server, etc. Very recently I decided to try to migrate the backend duties and database from the HTPC box to the server so that I only need to have one machine running 24/7. So, on the server, I installed mythtv-backend-master from the repository, which for 10.04 is version 0.23.0+fixes. You might have seen this one coming... when I try to import the database from the Mythbuntu box into the server's MythTV installation, I get an error message saying the database schema (1264) is newer than expected (1254).

So, I'm wondering about my options at this point. Is it reasonable to install the same version of MythTV on the server? What would be the best way of going about that?

Is there a way to easily revert the database schema to the earlier version that's required?

Will I just need to start over with a new database? (Hopefully not this one.)

Other options I haven't thought of?

Networking :: Installed Mysql As The Backend To PowerDNS?

Mar 17, 2011

I am marking this solved because I believe it is posted in the wrong forum. I will repost in Software. Sorry for the mistake. I have a small website that I want to host from home. I'm able to access it through the public IP but have not been successful in setting up the zones in PowerDns using PowerAdmin to resolve the domain name. I have read several sites regarding the issue but I still have no success. I'm hoping someone may be able to help with editing my master zone in order to resolve the domain name. I am using CentOS 5.5 to host the site and I've installed mysql as the backend to PowerDNS.

Server :: Web Interface For Backend File Transfer

Oct 11, 2010

setting up a basic apache webpage that would allow users to view files and folders on a server and transfer it from one directory to another? I know it doesn't sound very secure but this is an internal server so security is not a big issue as it is pretty secured in its network already. We have users that need to move files from one directory to another and we'd like to give them some intuitive interface to do this rather than having them log in to the linux system and run mv/cp commands. They are not very linux saavy.

PS: The system is running CENTOS 5.4.

Fedora :: KPackageKit: Failed To Initialize Packaging Backend?

Failed to initialize packaging backend. This may occur if other packaging tools are being used simultaneously.

Details: There are unfinished transactions remaining. Please run yum-complete-transaction as root.

I don't know anything about other packaging tools - I think I don't using any. Yum works fine in terminal. Reinstall PackageKit and KPackageKit files doesn't helped me. I also try to rebuilt rpm db:

rm -f /var/lib/rpm/__db*
rpm -vv --rebuilddb
yum clean all

I'm using Fedora 12 x86_64.

OpenSUSE Hardware :: Driver/ Backend For CanoScan 3000?

Mar 3, 2010

Have very recently installed Open S on my PC. As it's all really new 2 me have been strugling a bit to get things to work @ first. Now it's much better but my bleeping scanner won't work for love or money, apparently the Linux driver ( or should I say backend) for the thing has not been created. Its CanoScan 3000 and I still have the discs with Windows setup. Is there any way to get that thing work under Linux or should I get another scanner? Obviously, me writing the backend, is not really a very realistic option.

OpenSUSE Hardware :: SD Card Not Triggering PCI Backend After Boot?

When an SD card is inserted before/at boot time, everything works fine, meaning recognized by kernel and mounted to userspace.When an SD card is inserted after boot time, the kernel doesn't 'see' the hardware change not triggered, so no block device /dev/mmcblk0{p1}, so nothing to mount.This behavior is not openSuSE specific, when booting SystemRescueCD-2.0.1, the same behavior is noticed.SD card inserted after booting:

OpenSUSE Multimedia :: Configure Phonon's Xine Backend?

Jun 24, 2010

I have installed smplayer, and configured it to use the code...

Kaffeine (and dolphin's video preview) seem to use phonon's xine backend, and I can't find out what video output it uses. I'm guessing its plain old xv as it seems accelerated but turnes into a blue square when I move the window.

How do I tell the xine backend to use the same vo as smplayer?

OS 11.2 64 bit, KDE 4.4.4 (Factory)

(ps: I have a 'legacy' ATI graphics chip, xpress 200M working with the opensource radeon driver, which is brilliant btw).

OpenSUSE Multimedia :: KDE 4 Phonon Xine-backend Configuration

Sep 6, 2010

So I have made an interesting Discovery with regards to using KDE4 Kaffeine version 1 and Dolby Digital 5.1. The basic problem seems that there is no way to configure the Phonon xine Backend in KDE 4 for use with Kaffeine version 1. There is however, a xine-config file located at:


There appears to be no GUI way to change the default xine configuration (for use with KDE 4 applications) and while you can do so manually, the options seem bewildering, at least to me.

When you run xine-ui or Kaffeine/KDE3 there is an option to adjust the xine audio configuration using a GUI. Any changes made here are ignored by KDE 4 applications. As luck would have it you can copy the old xine configuration (adjusted by Kaffeine/KDE3) over the new one for Kaffeine in KDE4. The old text file configuration is located at:


If you were to use the old Kaffeine/KDE3 to adjust your xine audio configuration and then copy this file to the Kaffeine Version 1 KDE4 location, those changes should be used by the new version 1 Kaffeine in KDE 4. After Kaffeine/KDE3 audio settings work as you desire, open up a terminal session and make the following file copy. You must overwrite or rename the old configuration file for backup.

cp ~/.xine/config ~/.kde4/share/apps/kaffeine/xine-config

Since this new xine configuration is in the new Kaffeine version 1 KDE4 location, it may only modify how the new Kaffeine works and nothing else running in KDE4, but it is still an interesting find.

Ubuntu :: Delay MythTV Backend During Boot Process?

Apr 24, 2010

When I reboot my computer I cannot see my Tuner card until I manually restart the MythTV backend.

the problem is that the backend is being started before the drivers to the tuner card (HVR-2250). is there a way to change this.

I figure I should ask here as more people know there way around start up commands. I figure the easiest thing to do is to edit this file:


I would think adding a sleep or wait command would do the trick?
