General :: Like To Add And Remove Unused Or Needed Apps?
Jul 16, 2011
I haven't tried any random password patterns yet but I have tried knoppix because of a suggestion and it didn't work. I am useing knoppix as my OS not from CD or DVD. I would like to add and remove unused or needed apps. My linux language is week for the time being so I use the Software Center option from the Preferences option from the Main Menue.When I click on the remove icon a screen comes up asking for the Authentication Password and I don't have it, I as can not change the time on the desktop because it says that I am not the owner. How do I reset all the passwords and regain complete control of my system

i'm using ubuntu 10.10.
1. why is it that when i add a ppa to the repository and then i type sudo apt-get update,it has an error for that ppa but i can still install it? deluge is the main one that does that.
2. when i install apps, it tells me to use apt-get autoremove to remove unused packages but i need some of them like java etc. how do i take some apps off of the autoremove list?

An app failed to load properly and now i'm stuck in a sequence I don;t understand the solution for.
sudo apt-get autoremove
dpkg was interupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.

How can I remove an unused desktop? I am currently running Unity 2D. I can't run 3D, so I would like to remove it. Also, I want to try out other desktops so I will want to remove those (or Unity, depending on which I like better). I read somewhere that just doing sudo apt-get remove kde won't actually remove the entire desktop, so what else should I do.

According to System Monitor, my hard disc has a total size of 107.2 GiB, of which 6.7 GiB is "Free" and 1.3 GiB is available. I'm not sure if this is normal or not, though I know at least part of this wasted space is taken up by at least two failed attempts at creating Swap Files. Ubuntu says I have no Swap space whatsoever, so is there any way I can delete all these failed and unconnected Swap Files so that I could free up some spacend hopefully create one working one

I'm trying to Dual-boot Windows and Ubuntu. I have Ubuntu now. I'm trying to remove space from the Ubuntu partition(Active) but, it won't allow me to remove space from active partitions. I have 11GB Free according to GParted, yet during the installation it displays only 8MB Free. Oh, and I'm trying to install Windows XP through VirtualBox. Is that possible through the install CD? I've been searching and haven't seen anything about it.

Running # lsmod | grep -e " 0 " | wc on one of my servers running CentOS 5.5 (64 bits) reports me 32 unused modules, I mean, modules with 0 references. Am I wrong interpreting these results? If I'm not, how can I automatically clean those unused modules (i.e not manually running modprobe -r ). Some years ago there used to be a daemon called kerneld who was in charge of that task, right? What's CentOS new equivalent?

Sorry if it is a dumb question (i'm coming from deb/ubuntu and i'm totally new to rpm - installed Smeegol on a Samsung N150). After some try&error i finally got my Broadcom4313 working but underway to that i got lots of new kernels and now i don't understand not so much anymore.
I think the kernel default-devel it was me installing it using the distribution manager to get working make (for trying to install the original Broadcom driver package; i stopped that attempt because i didn't where exactly to move/cp the built driver).

I did "uname -a" and it's showing that I'm using 2.6.31-16-generic of the Linux Kernel. Now, in the GRUB2 boot menu, it's showing
2.6.31-14-generic & recovery
2.6.31-15-generic & recovery
and the current one: 2.6.31-16-generic & recovery.
I would like to remove the old ones because of the pileup they're creating.
Other info: I have wXP pro as my dualboot OS.

I can't find a Yum command to clean up no longer needed dependencies, you know similar to apt-get autoremove. Or does yum do this with the erase or remove command? btw: yum-clean-all just flushes out the cache right?

I was messing around trying to be able to download minecraft to my computer (it's very confusing for Linux, and I know nothing about this system!) Now when I try to install apps in the Software Center I get this error:
There seems to be a programming error in aptdaemon, the software that allows you to install/remove software and to perform other package management related tasks.
Traceback (most recent call last):
File "/usr/lib/python2.7/dist-packages/aptdaemon/worker.py", line 961, in simulate
trans.unauthenticated = self._simulate_helper(trans)
File "/usr/lib/python2.7/dist-packages/aptdaemon/worker.py", line 1085, in _simulate_helper
return depends, self._cache.required_download,
File "/usr/lib/python2.7/dist-packages/apt/cache.py", line 226, in required_download
pm.get_archives(fetcher, self._list, self._records)
SystemError: E:I wasn't able to locate file for the sun-java6-jre package. This might mean you need to manually fix this package.
I've seen a solution that seemed to work for someone else but when I go into the Terminal and type in the commands it asks for my sudo password and I have no idea what that means/is because I never set any kind of password like that.

Using Synaptic and/or terminal is great and so easy, but i have noticed that applications are not always the latest versions that are in the repository ie cups for instance So if i wanted to download the latest app from a website, what is the best way to install, based on having an earlier version already installed. Is it better to just install over an older version or remove the older version, and then install the new version clean
If you remove and older version of an application first, what is the best method for doing this and removing any residual files etc that might be left on your system?

everytime i try to install the updates from the update manager i get this error message:
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem. E: _cache->open() failed, i have tried running the sudo dpkg --configure -a in the terminal but when it asks for the password the keyboard stops working so i cant type anything into the terminal. can anyone help me fix this? My other problem was when i try to run the Add/Remove Applications i can't ever install any of the software because it says its "waiting for other tasks" i'm not sure why its doing this either.

I am looking to setup some computers as thinclients to connect to my MS Terminal Servers. We have a homebrew application that configures RDP sessions. A user logs into a webpage that dynamically generates a "launch.rdp" file. This file is generated to balance the load between servers.What I'd like to do is configure an image to boot up into Mozilla. When the user goes to the webpage, I'd like the launch.rdp file to open up in a terminal server session.I've tried with rdesktop and tsclient, but unfortunately neither would work with a "rdp" file.

I have not been on in about a month or 2. I have no idea how to list this thread. I am hoping that someone like tex can help out. Being lazy with ubuntu seems to have been badong. Ok, I had 2 physical machines and 3 vms. VM's ran under Vbox-ose via a bridge. OS's are buntu x2 and one centOS box. I installed webmin to make things easy ( i thought ).However, after setting webmin, my I have been randomly loosing PATH's. I mean, one minuet i can run sudo apt-get and the next the whole PATH is gone. I tried a compare of my "home" box's bashrc and bash_profile against the other machins, and outside of some alias for colr and the like nothing seems to stand out. Even if I su - to root I am not getting access to the needed paths. Now, while I could export the correct path, I am more conserned with the why of it all.
I would have thought that as long as my group setting on my ssh users were all correct AND the environment had not been changed, all would be good. I can provide more info if someone wants to help me out with this. HOwever, it drove me to a six pack. 8SI have read the man pages. I have used google. I have checked the logs. The logs by the way showed a lil hammering on one of the boxes for root access. [I]t wasnt me. However, I dont seem to be able to see a time stamp.

I installed the new Frugalware 1.2 via USB and that went well. I wanted an LXDE menu, as I don't like the "style" of the KDE menus, and the KDE menus seem slow, too.
The problem is that after installing LXDE, I have the LXDE menu from what I'd call the start button, which I like, but the KDE menu is now covering the entire screen on all desktops, and there seems no way to minimize it. I doubt I'll have to use it often, but don't want to lose all access to the programs on it. I haven't checked to see if all the programs are on the LXDE menu, but I noticed that Gfpm (the package manager) is now missing from the menu. Not sure if anything else has disappeared.
n Is there a way to minimize or hide the KDE menu?

On the ReadyNAS Duo, a RAID resync synchronizes the entire contents of one disk to another. It's a slow operation. So it's not something to be done lightly. By default, it is done whenever the unit is shut down uncleanly (generally the result of a hang or power interruption). It's something that can be disabled, though, such that a resync would be done only when manually requested. The authors of the software RAID driver in Linux (called "md") came up with a nice solution to the problem of slow RAID resyncs: the md driver allows you to assign a write intent bitmap to an md device, and where it's stored is configurable (the default is to store it on the md device in question, in the superblock). So when the array goes down unexpectedly (e.g., in a power outage), only the blocks that the md device was going to write will actually be resynced.
It's sort of like a journal for the md device itself. Now, the ReadyNAS Duo doesn't seem to use Linux md at all for implementing the RAID volume, but it does have an option to disable automatic resync in the event of an improper shutdown. And that leads to my question: how necessary is it to do a resync in such an event? If the Duo uses the same method as the Linux md driver, then obviously such a resync would rarely be necessary. But if it doesn't, then it would be the equivalent of using the md driver without a write-intent bitmap, and a resync would almost certainly be necessary in the event of an improper shutdown. Does the Duo (and maybe other units) use the equivalent of a write intent bitmap for RAID write operations?

I am trying to figure out how to make my terminal emulator dynamically transparent ( see through to the action below that window - Browser, video et cettera and not just the default wallpaper) . I figured out how to make transparent but not "dynamic". I have seen people mentioned you need to enable compositing but I am unsure how to do that in Gnome. I recall from a prior use of XFCE this was an option in that WM but I can't find in Gnome or compiz (if needed)
I am running Gnome on Debian Squeeze and have installed compiz. Any direction would be appreciated. I find reading web tutorials through the terminal to be very helpful so I can practice the command line or even practice commands while watching a good video .
