CentOS 5 :: Remove Applications Without Harming System?
Dec 17, 2009
I'm using x86_64 CentOS 5.4. There are some 32bit applications on my system. Does these applications work on 64bit platform. If not, how can I remove these applications without harming my system.
I would like to remove Mint and recover that space for Ubuntu, but since I installed Mint last, I think it is "in charge" of the grub bootloader, so I figured if I just expanded the ubuntu partition then I would lose the bootloader and not be able to log into anything. Is this the case? what is the best way to remove mint while still preserving the grub menu.
I currently have both Ubuntu 9.10 and Windows XP installed on my PC. I want to remove the Ubuntu partition and leave the Windows partition. The question that I have is that when I remove it, Grub will go with it. Will that mess up my Windows partition?
What I need to do is remove Ubuntu and add the hdd space back to the other partition. I just don't want Grub's absence to keep me from being able to load Windows.
I recently had to power off my Centos 5.5 box (ungraceful shutdown). When it came back up, three apps popped up: "Welcome to the Gnome Help Browser" (which is Yelp). In another desktop, Konqueror is waiting for a login. This happens every time I restart my system. I haven't been able to figure out how to stop this. Every time I've shut down my system since I had to bring it down hard, it's been gracefully and neither of those apps was running.
I haven't used Ubuntu for a while, and just reinstalled it. I have one major dislike about the new version, There are several applications I click on and it takes me to the installer.How do I remove those types of applications or just install them all?
Continuing on my quest to build a system with sole purpose of being a LAMP server, I am trying to have the bare minimum number of packages installed. I'm not trying to disable as many deamons as possible, but actually remove any package that is not required. It might sound a bit extreme but each package that is installed that is not needed is using valuable space on the expensive (and small) 36GB 15krpm SAS disk.
Also it is a damage control approach, in that assuming a cracker finds an exploit in Apache or PHP that allows them to run executables on the filesystem then taking away as many tools as possible will help in damage limitation. For example I don't want an SSH client installed on the system as it has no purpose for me but could be used by a cracker to access other systems on the network, if they compromise that system.
I have installed the absolute minimum from the 5.3 install by deselecting everything during install but that still leaves a great deal of unnecessary packages installed. Seeing as how the system is a 64bit installation and will have no 32bit apps running on it I have first uninstalled all the i386 versions of various libraries. I presume their only function is to provide compatibility for 32bit apps.
I have been looking for information about removing other packages but I don't seem to be able to find information on real dependancies. For example I believe I have no need for dmraid as it is for managing software RAID arrays that I have no intention using. but if I attempt to remove it the dependancies include kernel and mkinitrd. What I can't figure out though is if these are hard dependancies in that those packages will fail to work or soft ones that simply mean without dmraid it will not be possible to configure the software raid module that is loaded into the kernel.
What packages would people recommend to remove, anyone seen a good guide to reducing down CentOS/RHEL to the absolute minimum ? python-elementtree-1.2.6 : Is this really required by YUM ? m2crypto-0.16 x86_64 : Is this really used by YUM, I didn't think YUM connected via SSL ?
when a remove a user from the system using the domain userdel guest the user gets removed but the /home/guest doesn't get removed so i remove it by command rm -rf /home/guest then i recreate the user by giving in the command useradd guest now it gives the error mailbox file already exists what does it mean when it says so though this command creates the user.
I get to my specific problem, I'm running Xubuntu 9.10 (karmic) on a Playstation 3 (PPC). I am attempting to install "Qemu-launcher".
1. Tried to install "qemu-launcher" via "Add / Remove Applications". it gave me an error about conflicting packages, and deferred me to Synaptic Package Manager.
2. Tried to install "qemu-launcher" in Synaptic Package Manager. error: "Could not mark all packages for installation or upgrade -- the following packages have unresolvable dependencies. Make sure that all required repositories are added and enabled in the preferences. -- qemu-launcher: Depends: qemu-kvm (>=0.11.0~rc1) but it is not installable"
3. Tried to download "qemu-launcher" via "apt-get" in terminal - same error as in Synaptic
4. Attempted to download "qemu-kvm" via "apt-get" in terminal: "package qemu-kvm is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source. E: package qemu-kvm has no installation candidate."
5. Found and downloaded "qemu-kvm-0.11.0~rc1.orig.tar.gz". Extracted archive.
I was wondering why some programs are removed when doing a (partial) upgrade. For instance the Nvidia drivers, the network manager and some other server components are removed.
This is very annoying since you're receiving updates on a regular basis.

If I'm perfectly honest, I really don't like the "messaging menu". I don't like the way it's a single point that lumps all sorts of messages together. From a socialite's perspective, I'm sure it's awesome... from a more business orientated perspective, it's cumbersom - the icon is green, does that mean I have an important email, a new post has popped up on my RSS feed (via Liferea), or is it just Bob saying "Hi" in Empathy... I won't know until I click it I would rather have separate notification icons for the individual applications, just like it used to be. Now, I know how to remove application from the Messaging Menu... or at least I thought I did.
I just tried removing 'gwibber' from /usr/share/indicators/messages/applications I have stopped using Empathy (I have used Pidgin/GAIM for a lot longer and I'm stuck in my ways ), so that's gone. I have removed the PPA version of Liferea that had Message Menu integration, so that's gone. I have removed Evolution as I use (and have done so for ~10 years) ClawsMail, so that's gone. The last thing I want to get rid of is Gwibber. I like Gwibber, I just don't want it in the Messaging Menu.
We all know that we can remove installed applications straight from terminal or ubuntu software center. However, sometimes we download .deb files from the web that are not necessarily on the repository. My question is, how do I uninstall a manually installed deb application?
I am unable to remove or install any applications using software centre or update manager or thru terminal. I have ubuntu 10.10 installed.This happened after i tried to install crossplatfromUI application for using Reliance Netconnect device. The device is working without this file. I tried to use the janitor and Synaptic but does not work. I tried what was given here. I am adding the text what i have got after trying some commands given in the thread.
Code: sudo apt-get install -f [sudo] password for murari: Reading package lists... Done Building dependency tree Reading state information... Done
Want to remove programs with no explanations on how to use so used pkgtool to remove gxine, xine, and xmms. When I try to remove juK or Dragon Player, they do not show up in pkgtool list. Dragon Player will not now run from the multimedia list and JuK can't run after starting because it is missing files which were removed by pkgtool above. How do I now go about finding and removing these last two?
I had some problems about a week ago with installing Python2.6-minimal (as an issue, it got resolved), however, after the problem was resolved, 'Add/Remove Applications' disappeared after upgrade was complete. I usually do not use this program for installing, etc., if I can help it, but do use it more often for web address reference when I am considering installing a new program, etc. Question is,is there some way to find out if it is merely lurking somewhere in my system... & then to once again add it to my menu list? Or, if that is not the case, to reinstall it via apt-get, aptitude, or some way like this? I could not find this application (or whatever it is called) in the Synaptic Package Manager.
When I tried to uninstall some applications, pidgin, for example, via 'Add/Remove Software', YaST told me that I have to uninstall another 200+ packages. Is this something normal? I'm new to Linux and don't want ruin the system, so I seek for another way.
I found that 'Software Manager' can also be used to uninstall the package, so I use it to uninstall pidgin. The problem is after I pressed 'Apply' button, there are so many package installing by themselves. I saw that most of them are appended with '-lang'.
I'd imagine I sound like a complete clown but I am completely new to ubunto and linux in general. Having "fiddled around with it" for a matter of weeks I am finding generally I am quite pleased and am taking my time sorting through the chaff. Talking of chaff I have a problem from downloading a program previously which turned out to be unnecessary. Avast, I have removed the program and associated files but for some reason an Icon remains in the applications box at the bottom, not in a grouped file. I have tried various terminal commands taken from forums etc but none of these appear to have done the trick. A simple right click doesnt give me a remove to waste basket option and the drag and drop to waste basket doesn't work either. Amongst terminal efforts force remove etc etc., don't have any affect and the lines about the avast file does not exist.
How does one remove the Dictionary listed under Applications/Office? It's not obvious - I could not find a way to do it either through the Ubuntu Software Centre or the Synaptic Package Manager route.
In gnome 3, when I go to activities>applications I either have duplicates (sometimes I do and sometimes I don't) of some programs or no icons for the ones I uninstalled, but they are still there. How do I hide/delete them?
Half of my hard drive is an unused partition, which is formatted ext2 which is just temporal and has no specific intention of mine. This unused partition has its own swap area, which is also a temporal and not important.
So my HD is:
Now, I'd like installing Windows 7 using these sda2 and sda4 partitions without corrupting current Linux installation and its GRUB2 setting(I'd likt to reconfigure the GRUB2 after successfully installing the Windows image, for the dual-boot).
I've installed Debian GNU/Linux, from a Testing NetInstall ISO, then after setting up the system, I've installed the KDE desktop.Well, I like to have a system with the applications I want, not the applications that the system wants for me, I mean, that's the point of GNU/Linux, isn't?
Thus I want to remove some applications from KDE, let's say KWrite. I know it's a good text editor, but Kate is way better, at least for me, and... I should have the authority to decide what applications I want on my system, I think you got the point.So I installed Kate, and when I try to remove KWrite, APT asks me to remove nothing but this applications: kde-baseapps kde-plasma-desktop.
I don't understand why do KDE forces me to get rid of the entire desktop... when I'm just trying to remove a single application, and a replacement it's already installed.
how can i remove 'applications' and 'files and folders' launchers from unity in Ubuntu 11.04? Because applications and files and folders are already accessible from typing in the search box which gets opened clicking the top most left button.
I have C: and D: on my computer. the D drive has 250 GB of free space. I would like to install it on the D drive without harming my existing windows. I have booted through an USB and it has an icon that says "install fedora on your hard disk". How do I make sure that it will be installed only my D drive without harming my windows?
On my local apache web server I had installed gnome desktop, because I wanted it to use as a TV. But when I installed the gnome desktop, my requests for web pages became terribly slow (4-5 seconds!). When I deinstalled the gnome desktop, the request where fast again. But I still want to watch TV on my server, so I wander if people know why the gnome desktop harms the performance of the server?
PS. with gnome desktop, ping was <1 ms, samba server worked like charm, wget localhost was <1 ms, but for some reason, when tried to get a webpage from my webserver to a remote machine, it took seriously 4-5 seconds to load a page.
Recently I have installed Fedora 10. It comes with firefox 3.xx by default. Now I was wondering if there is any way through which i can update it to 3.5 version though yum. I have tried yum update firefox but it did not work and returns following messages Loaded plugins: refresh-packagekit Setting up Update Process No Packages marked for Update I know that one way to update is download the latest Tar package and use it, but I want to totally remove my previous installation and use solely one package i.e. firefox 3.5.
I've searched all over Google and searched the forums and I have not been successful in finding out how to disable the System Bell (Beep) computer-wide. It's annoying hearing this extremely loud "BEEP" when I hit backspace one too many times, even when my sound is muted. People look at me like I'm crazy. Even if I try to backspace a non-existent character in my Google Chrome browser, I am struck with a crazy Error Beep. Long story short, how do I disable the System-wide "System Bell" ("BEEP") permanently? I'm on OpenSuse 11.3 using the KDE 4.4.4 Desktop.
Are there any tutorials for this? My sister wants a really easy application that pops a random quotation every time she presses on an icon (probably appearing in the panel). I'm fairly experienced in programming, but i've never done desktop apps for ubuntu.
