How does package management in Debian work?
What are all these commands like apt-get, apt-cache, dpkg, dpkg-deb, dpkg-query, etc? What are their roles?
how to install software in Ubuntu.
I am new to Debian but a long term user of various other Linux distros, most commonly Ubuntu at home and Xubuntu for my old work computer. I tried Debian 6 LXDE the other day on the older PC, from a live LXF disc. It picked up all my hardware automatically and was so stable (more so than the Xubuntu LXDE distro on the HD) that I decided to install it.
Now that it is on the HD it is still very stable, but I am struggling with package management and installing "stuff".
I am fairly comfortable with the CLI and have managed to get myself into the sudoers group, install grub and add the old Xubuntu to grub manually (I was not impressed that Debian didn't pick up the other two distros on the machine, even after a grub install and update grub and all the other tricks I could think of).
Anyway, back to package mngt:
First, why is there no pdf viewer/reader by default? How do you start building if you can't read the many helpful articles in pdf?
But more annoying, when I try to install pdfedit, epdfview, evince, okular, pdf-viewer, osso-pdf-viewer or kpdf (at least one of which MUST work in Debian LXDE) using "apt-get install" or "aptitude install", as root or as sudo in the Terminal, why do I get "Couldn't find any package whose name or description matched" "Couldn't find package" or "Unable to locate package"? I can't even install synaptic to help!
Then I found that my sources.lst only listed the install CD as a repository (how stupid is that?) so added some repositories to it (eg deb http://http.us.debian.org/debian stable main contrib non-free) and did a sudo apt-get update. And apt STILL can't find anything.
And what is that Debian Installer in the >Menu>System Tools? It asks for a password then nothing opens that I can detect. Is there a GUI for package mngt?
I'm looking to upgrade a few packages but noticed that the version available through Yum isn't necessarily the most up-to-date version as per the package website. One such example is Mysql:
[root@localhost ~]# yum info mysql-server
Loading "installonlyn" plugin
Setting up repositories
[code]....
If you look on the mysql website, the latest community edition is 5.1.50. I suspect the answer might be to do a distribution upgrade via media (i.e.: burn a CD) however was wondering if there's any ways around that?
I've come from Fedora and am trying out Arch Linux. I was wondering if the packager 'pacman' contains funcionality like that provided by 'yum whatprovides': provides or whatprovides Is used to find out which package provides some feature or file. Just use a specific name or a file- glob-syntax wildcards to list the packages available or installed that provide that feature or file.

Since the problem seemed more related to the raid controller than the disks (the disks still responded and I was able to restore their contents with some trickery), I got myself a QNAP NAS TS-119 as a replacement, installed Debian on it and wanted to install the original set of packages to the new platform.Instead of simply installing all packages on the QNAP that were on the old x86 box, I wanted to maintain the status of automatically installed packages in aptitude.
After looking at /var/lib/aptitude/pkgstates and a bit of confusionI looked at the aptitude source code and found the following rather simple explanation:Aptitude merges the package status information from apt and aptitude without storing redundant information in its own status file (which is good). This means the information aboutckages that were automatically installed is tracked in /var/lib/apt/extended_states.This may seem trivial but I couldn't find this information on the Internet I thought I'd submit a dummy question here in case others are havng similar problems.For the sake of completeness: There seem to be situations (like pending actions) where aptitude will store auto-install information in its own state file, /var/lib/aptitude/pkgstates.
I've been looking and trying various programs to replace my beloved Wallpaper-Tray on my new Ubuntu 10.04 setup. The problem is, nothing seems to be able to work with my dual monitors like wallpaper-tray did.
Drapes, Wally, Nitrogen, and Wallpapoz are all pretty worthless when it comes to dual monitors. I am looking for something that will stretch my dual-screen wallpaper across both screens like wallpaper-tray did. Drapes comes close by centering a wallpaper in the middle of both screens - but if it can't stretch it across both screens then that's a deal-breaker for me. Not all my dual screen wallpapers are 3840x1200. Also, drapes was giving me errors every time at startup....very annoying.
Or am I just missing something with the programs I've been trying? It's surprising that those programs wouldn't have more options available for dual monitor setups.
When I run zypper dup I get this message :
System management is locked by the application with pid 3787 (/usr/sbin/packagekitd).
Close this application before trying again.
How do I do this?
I've gone though the system purging/removing what I don't require on my Fedora install using the graphical tool in gnome 3. I then used package-cleanup --leaves to clean up some cruft left behind. yum list installed shows I still have 1031 packages installed, which is about 400 more than similar setups I used to have on Debian, and truthfully on Debian I have more stuff installed that I've still got to install here (gimp, nvidia drivers, etc).
I see a buch of stuff in yum list installed I don't need, so I can use yum remove foo to cleanup some more, but I'm wondering if there's another graphical interface or perhaps and advacned option in the add/remove software application I've been using thus far.
I might switch to OpenSUSE from Debian, but I have my doubts still about package management with OpenSUSE. I'm glad to see that zypper now has the --clean-deps option. Is there a YAST GUI for this as well? I don't like the command line very much. Additionally, is there any way to remove a package with all its config files? In Debian with the Synaptic front end, you can right click on package and click "remove" and it will just uninstall the package but leave its configuration files intact.
But if you select "Completely Remove" it will remove all the configuration files so that if you later install the package again it will use the default settings once again. Is there any way to do this with OpenSUSE? Again, I'd prefer a GUI. Does 11.3 offer Delta RPM updates, and are there many repos that offer delta RPMs? Does Zypper cache downloaded packages by default? And using the YAST package management GUI are packages caches by default? If so, where? Does the YAST GUI try to refresh the package cache all the time, or can I do it manually?
I JUST got back on my laptop now that I have my new A/C adapter, and guess what? The package management system is broken! Which sucks, because I have quite a bit of updates to install.
Here's the details provided by Synaptic when installing the new version of AWN:
Code:
I finally convinced my wife to remove Windows from her Acer Aspire 5680 and instead to use OpenSuse, but unfortunately I am having some major trouble for no reason.
You see as soon as I installed the OS, I tried to add some new programs, like Thunderbird, etc but I keep getting an Accessing the Package Management failed error message. It says that it can't continue because process 9172 is blocking it. But I opened the System Monitor and can't find the **** 9172! My OpenSuse installation doesn't have this problem.
how to fix it? I can't install or update any software at all!

I have been playing around with quickly, and installed the package for my application. The install failed. Worse, none of my package managers can install anything anymore - I get the error
Code:
E: The package swift needs to be reinstalled, but I can't find an archive for it. This seems to be the same problem as here [URL] But I cannot fix it in the same way as there is no online package for me to reinstall. When I try to install the .deb I get a message that it is either corrupted or the permissions are wrong.
I'm having trouble understanding the principles behind OpenSuse package and repository management. Here is a concrete example: I want to install the 32bit version of glibc. (using zypper) Naturally I write 'wp glibc' to see what's available. Output:
[Code]....
I'm looking for the (32bit) tokyocabinet library. I go through all the hoops like I did in the first example. Nothing shows up! How is that possible? Does opensuse really not have this library in any repository? Does that mean I have to install from source? How can I be sure that zypper searches through all repositories?
Umarks is no longer under development.

Any ideas? (or better, inside info from someone who knows)

One suggestion mentioned is that Ubuntu change from debian to rpm package format. Could someone please tell me why rpm is better? I have only tried an rpm distro a couple of years ago with Mandriva and with a live-cd now-and-again. But, I never have used one long enough to experience why it might be better. Why is rpm better? Or, are those folks at LXF wrong?

View 2 Replies View RelatedI tried following this tutorial on how to create a Debian/Ubuntu package and ran into the following stumbling block: When I tried installing debmake (a tool to easily create Debian packages; trying to debian-package a jhbuild prefix and upload it to a PPA) I got an error from APT saying that the package was not found.After an extensive Google search, I noticed that the package was only used in Ubuntu up to Hardy and after that was deprecated. Why? Did dpkg-dev suddenly include the deb-make command in its package or something?
After reading the deprecation announcement on the mailing list located in the Google search it seems as though debhelper replaces debmake.
How do we perform offline patch management with Debian? This isn't a question about which tools to use on Debian to load the patch once it is on a CD and transferred to said offline computer via sneaker net. More, how do I keep said offline (or strictly firewalled) computer in synch?
Pardon me while I make a comparison to Solaris. I am in no way stating Solaris is better. It just happens to be my baseline of experience.In Solaris, I can download Cluster Patch Updates (CPU). So if I build a Solaris box with a CD that is a year or more old, I can download the latest CPU and get the box patched up to date, and from that point on sneaker-net patches as they appear.
We have an Apache Subversion (http) server for hosting our codes, and, for the 3 next month, we are behind a DSL connection (max upload 100 kB/s).
When a remote co-worker try to download a new fresh copy of our projects on his computer directly over http, the transfer goes fine : with a bandwidth monitor (gnome-system-monitor or bwm-ng) we can see that the server is trying to send ~95kB/s and the connection remains usable for others task in parallel (just a bit slower, which is normal).
But : when the remote co-worker is connected through SSH to this server, and uses tunneling to communicate with Apache Subversion, the server is sending more than 200kB/s : the connection is not usable for other tasks during the transfer as with ~102kB/s actually transferred through the DSL Line, it's completely congested and more than fifty percents of the packets are lost.
I think that I understand why : TCP/IP auto-detects the max amount of successfully transmitted bytes per second, and try not send more than this maximum value.
When the Apache server is connected to the local instance of openssh-server through localhost, packets are transmitted successfully between them. Only after, openssh-server try to send it to the client (and should retry if it's not successfull) but during that time, Apache is already giving the next one... giving this saturation effect (Apache is not aware of the saturation, or at least, not enough)
I recently converted a Toshiba Satellite A75 notebook with a broken screen into a minecraft server that me and my friends will be using at UAB. It's currently running the latest version of Debian in text-mode with a few shell scripts that backup files and update a webpage at specified times.
The server runs fantastic ( though it's currently on my home network so no one can join it unless they are on LAN ) but there is a minor problem. I took a look at the backups from last night and it seems the server shut down around 10:00 in the morning because the laptop went into sleep/hibernate mode or something like that. I'm not sure what's causing this exactly but I think it's some setting in gnome-power-manager, but I can't run it in text mode.
what do I need to add to /etc/apt/sources.list? can't really understand the howtos and tutorials
View 7 Replies View RelatedI have recently upgraded the hardware of my zenbook from i5 to i7. Unfortunately the battery discharges very fast (30 min instead 3 h with i5) because the system turns all time at maximum speed (I guess).
Is there any power management update for Debian Jessie8.3 on i7 processors?
We would like to setup Lenny (Gnome) clients and need Desktop Mgmt Software, to manage clients over central management system.
