General :: Preventing Package Installation In Ubuntu 11.04?
May 1, 2011
I'm in the process of installing the usual Python/Numpy/Scipy/Matplotlib combination. I'm using the installed version of Python (2.7) on Ubuntu 11.04 but I've compiled Numpy and Scipy (and ATLAS/LAPACK etc.) from source. I now want to install matplotlib from the repositories but every time I do python-numpy is installed as a dependency of python-matplotlib. I've tried "apt-get hold python-numpy" etc. and also locking the version of each package in synaptic but both synaptic and apt-get will happily install the packages when requested, I assume because hold/lock version don't work on packages that aren't yet installed.
How can I prevent these packages being installed? Or is there a way to tell Ubuntu that I already have versions?

I do not want my windows to be dragged and placed partially in two desktops. However, I have enabled Edge flipping to move window to next desktop. My problem is with partial overlap. Something which makes the windows stay completely in the desktop, but at the same time allow edge flipping.

So earlier today I was running out of space on my regular Windows 7 partition and I played around with extending it. I ended up somehow deleting grub and messing up my entire system. I've spent the last 2 hours looking for the answer to this and everyone has been saying to boot from a live disk and fix it that way.
Well, I've tried everything, the only way I can boot right now is via USB and it will NOT allow me to. I checked on other computers and even re-installed and formatted by external hard drive to try and get it to work and it refuses. I've changed my BIOS to boot from USB so I have no idea as to why this is happening. Also, I've tried using the "ls" command to find my partition via "ls (hdX,Y)/" and all of them come up as unknown filesystems.

I have taken much time and effort to get Mediatomb working on my new machine running Maverick Server, with GUI. Those of you who run Mediatomb know that it's pretty convoluted to get everything "just right".I have located the three Mediatomb packages in Synaptec and marked them as "lock version" in the hope that they will not be up(side)graded to a slightly different version of Mediatomb, which does not have Javascript enabled however, update manager still insists on trying to make the change to the other version .

Does anyone know of a linux utility which will prevent all memory in a forked process from being swapped out to disk? I've seen the 'mlockall' call, but hacking the app sounds like overkill.My reason for needing this is that I'm running Windows XP under VirtualBox on my linux netbook, and I'm concerned there are basically two levels of swapping going on, which on a single dinky netbook hard disk isn't

I like less and use it as my default pager in Linux. However, there are times that I am scrolling down through a large document quickly and less exits when I reach the end of the document before I have time to stop scrolling. I'd like less to exit only I type q, and not because I ask it to scroll beyond the end of the document. Is that possible?

I need to prevent udev from creating the /dev/v4l/by-path/* and /dev/v4l/by-id/* files upon connecting my webcam. The problem is that Kopete doesn't want to display the video if these files are present. It works fine if I remove them, but I'd rather not have them created in the first place, since they seem to be completely useless anyway.

just did a dual boot or whatever you call it last night)and I can't figure out how to connect to my home wireless internet. I checked in one of the menus, and it says "firmware missing". Does anybody have an idea of what I need to do to fix this? If I haven't been specific enough, please ask for more information. I'm not really sure what to include.

I am currently using the windows version of gVim to edit source files on a networked drive mapped to a linux system, as well as local files created in cygwin.
The problem is that the windows version of gVim destroys the original file permissions on the respective systems. IE: Files on cygwin are defaulted to 077. When edited by the windows version of vim they are saved as 777.This problem doesn't even occur when using ms-notepad (as well as all other editors I've tried), so I am not quite sure why gVim does it.
A possible solution would be to use cygwin's gVim for everything, but that's rather cumbersome as it requires running an x11 environment to support it, and it causes some problems when running some commands from within gVim (or vim for that matter) when working on the networked drive.
Any ideas how I might be able to maintain the existing file permissions?
This morning while on a different machine the problem with cygwin did not occur. Cygwin & gVim were the same version, however the other machine is running WinXP while the machine the problem is occurring on runs Win7.

I'm trying to run a shell script on a kern board (av1100) that shows some text output on the attached screen. The big problem is that the screen goes to blank in like 2 minutes.I'd just like to have the script showing it's output while the thing is on.Isn't there a command to stop the screen from going to blank?p.s. there is no bash available, just #!/bin/sh
Code:
#!/bin/sh

I just finished installing a dual boot XP/Ubuntu 10.04 LTS for desktop about half an hour ago, and it's my first experience with a Linux OS. Now that my *complete idiot noob* flag is flying, I have an error I think I need to report:An error occurs with the Package Manager, I get this message when I try to run it, and when Ubuntu boots:
E: Encountered a Package with no Package: header
E: Problem with MergeList /var/lib/apt/lists/
us.archive.ubuntu.com_ubuntu_dists_lucid_restricte d_binary-i386_Packages
E: The package lists or status file could not be parsed or opened.
This usually means that your installed packages have unmet dependencies I tried to download and install Chrome, and it came up with a similar error.
Is my install corrupt/incomplete or something? My setup is a P4 2.4Ghz, 512Mb RAM, onboard graphics, wireless internet and the HDD is 40GB, split into 2 partitions, and my Ubuntu Partition is 10 GB. I'm running Ubuntu 10.04 LTS distribution, and the other OS is Windows XP Professional SP3.I installed Ubuntu by using the Wubi installer.

I'm trying to install Gnomad and have got this far. I type ./configure and everything looks like its kinda working then it says
"No package 'glib-2.0' found
No package 'gthread-2.0' found
No package 'libnjb' found
No package 'gtk+-2.0' found
Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables GN_CFLAGS and GN_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details."

I have a Win vista dual booted with ubuntu, no problem there, all's well. I used live-usb to make a bootable USB with centos 5.0 I created the usb and it will boot just fine. The problem I run into is updating the installation with the package manager. I run the manager and the system prompts for reboot and I get this error:

Is there anyway to show package size that comes up in the search so you don't have to apt-get install package individually and wait for the installation initiation and then reject to install after it gives u the [y/N] confirmation thing?

I have a headless Jaunty server that I need to access from both mac and PC clients. If the server has been rebooted, I can SSH into it, but I can not VNC into it unless I unlock the keychain. The problem is that I can't figure out how to unlock the keychain from SSH connections, so the only available method is to attach a keyboard to the physical box and enter the keychain password at the server itself.Is there a Terminal command that I can use to unlock the keychain? I have seen references to the 'security' command but that appears to be unavailable to Jaunty?
Is there an even better method than a Terminal command? I don't want to be putting passwords into the Terminal log if I can help it. Ideally, I would connect via SSH, confirm the keychain somehow, and tunnel in through VNC.

This is a bit of an odd one, it's not so much about using Ubuntu but about *not* using Ubuntu. I am just setting up a new computer for my daughter. I have spent days configuring parental controls and lockdowns and such to stop her from being able to view unsuitable content, download programs I don't want, anything that can mess up the computer, etc. etc. At this age I am going to be over her shoulder 100% of the time while she works anyway, but something that occurs to me is that having set up all this control software in Windows, she could actually override the entire thing really easily by booting from a live CD, USB key or similar, she can keep a whole OS in her pocket and I'd never know. You can only watch so much of the time as they grow up.Can I prevent a computer from being capable of booting from external media without some kind of password? How would you begin to go about that?

I just want to prevent updates from certain repos, which are intended only for installation purposes. Those repos, however, also include updates for officially bundled packages, and i dont want to update them - just want to keep those as official versions.

Since my desktop (Ubuntu 10.4.1 for now) has no need for anyone trying to ssh into it, I want to prevent ssh from starting as a service when I boot up.
If I type: sudo update-rc.d -f ssh-agent remove
in terminal, will that stop the service for all boots (until I run: sudo update-rc.d ssh-agent defaults -- in terminal)?
I've already removed (unchecked) ssh agent key from my startup applications
