Debian :: Check That A Deb Will Not Overwrite Anything?
Feb 25, 2011
I have this deb from a package in unstable...
It calls for libhdf5-openmpi, which is not compatible with libhdf5-serial which in turn is used by several packages that i have installed...
It's either the serial or the openmpi version... not both.
Since this specific package from sid calls for this dependence, which way do i have to check that if i override dependency checking it wont overwrite anything along the way...?
All other dependencies can be met... except this particular one...
And i wont be using the functionality that calls for openmpi...
I already have a Notebook with windows (for some reason it needs 3 partitions..) and wheezy. When I installed wheezy I create 2 logical partition inside a primary one: one logical for /home and the other one for filesystem. Now I would like to overwrite wheezy and get get jessie, but without touching windows and home.
I already try to upgrading and it went wrong, so I prefer overwrite, what I have to do during "manual installation" phase?
While updating and upgrading, I got this at the command prompt:
Code: Select all ==> Modified (by you or by a script) since installation. ==> Package distributor has shipped an updated version. What would you like to do about it ? Your options are: Y or I : install the package maintainer's version N or O : keep your currently-installed version D : show the differences between the versions Z : start a shell to examine the situation
The default action is to keep your current version.
I am new to Debian but not Linux-based systems. I have been experimenting a lot with Debian Lenny/Squeeze. I am growing more comfortable each day with the Debian design. Yet there remain many unexplored areas. I am creating a migration check list. Things to check, prepare, or reconfigure when moving from one Linux-based system to Debian.
I have a good computer background and my current check list probably is fairly good. Yet I would appreciate input and opinions from experienced Debian users of things to watch in such a migration. Login defs, passwd/group files, different directory locations, keymaps, services and daemons, etc. I am not too concerned with the desktop as I plan to stick with KDE 3.5 for a while and I can basically move those settings across.
I'm trying to connect to the VPN of my employer; after fix various minor issues I reach this point in which the DNS entries and the default gateway of the VPN are overwritten with the values of the eth0 device that appears by default. Therefore the vpn is not useful.
Below is the recipe I've used to compile dwm from source on Squeeze
su apt-get install devscripts debian-keyring apt-get build-dep dwm exit
It all seems to work, however debuild gave an error about secret keys. Is this a sensible procedure? What happens in the (probably unlikely) event there is another source patch?I've gone to a tiling window manager as the result of the purchase of a wide screen LCD monitor. I like to have some stuff down the right hand side when running Firefox and OpenOffice in the main panes. Any configuration tricks welcome. Modern screens are the wrong shape!
i am making the shift from centos to debian as i have heard that debian has lot of packages compared to centos and can make you learn more,i want to know how can i match the md5sum provided on the download page with the DVD images
I am not sure whether I ask this question on the right forum. My debian mailserver is depending on a MySQL database. Every reboot it takes around 30 minutes to boot because of the database check. I could not find the right command or setting to boot without this check. Do you know how to do this.
But, given that I've mixed some source and unstable packages in with my stable system, I'm now experiencing a few eccentricities (which really should make me swear off screwing around with my system, but, alas, I don't seem to learn from experience).
I digress. Anyway, in trying to play cdroms (with xplaycd and with kaffeine), it does not work. Kaffeine gives me the following feedback:
Code: The host you're trying to connect is unknown.
Check the validity of the specified hostname. (unable to resolve)
How to use cp command without to overwrite target file permissionsFor examplecp /tmp/file /home/fileI dont want to change chown and chgrp on /home/file
Is it possible to check out the log as well when you are checking out a version from some repo. For instance this is a game I like :-
[Code]...
The game is called dawn-rpg and one can find about it at dawn-rpg.sourceforge.net but that's not what I want to talk about. The thing it would be so much more convenient for me if instead of going to the svn mirror or whatever it is and checking out the log, it was local. I know I could do something like this :-
svn log > svnlog150611.txt
This would download the log file and put the contents in some text file I have named as svnlog150611.txt . The problem with this way of doing things is that each time I have to check out I would have to create a new txt file with that date. If there was a way one could check out the log as well when checking out a new version/release it would be nice. Its also possible that this might be already be there and there might be another command to use locally that I am not aware about. In that case, would look forward to people to share the same.
I want to install Debian Stable 8 Jessie. I've tried the main website, of course, first. But there are a lot of options there to download Debian 8: CD, DVD, Live etc. I downloaded debian-live-8.0.0-amd64-lxde-desktop.iso and I booted live in VirtualBox. It boots fine and the operating system looks in order.
Questions/problems:
1. The desktop icon for the installer says "Install Debian sid". But from what I know "sid" is unstable version. I do not want unstable, nor testing. I just want normal Stable. Did I got the wrong version? The website is a bit confusing about which version is which.
2. How do I check the md5 of the iso? I know how to do that with other distros, they usually specify it near the download link and I can execute in terminal the command 'md5sum' followed by the specific linux distro iso and then compare the numbers. But I can find no such thing for Debian. I searched the website but could not find any clear info.
3. After I install, what should I do in order to make Iceweasel work with Flash and multimedia codecs? I also need Skype and the proprietary Nvidia drivers.
And if I enable these non free, do I get automatic updates for them like for the rest of standard Debian software? Or, if not, what should I do?
The idea is that I want a system that is as stable and bug free as possible, but I won't use many apps beyond these ones. I don't need the latest and greatest software as long as these get security updates. Should I be ok with this configuration?
Also how do I check the latest version available? I gather to update a driver I need to update the kernel so ill not be doing that but im trying to get more familiar with linux here. I know how to do this in windows so it would be good to be able to check driver versions in linux too. Im on debian 8.1 with intel HD4400 graphics.
How do you check if a computer's video card will support Kernel Mode Switching BEFORE OS installation?
In this example I have an Acer Aspire AST180-UA381B.
Manufacture website says my video card is: Integrated nVidia MCP61
[URL] ....
Nouveau code list says: NV4C (MCP61) GeForce 6150LE / nForce 400/405, GeForce 6150SE Quadro NVS 210s / nForce 430
[URL] ....
I want to know:
1. How to tell if my graphics card will support KMS before I install the OS?
2. If it does not support KMS which kernel options should be passed to get it to work properly with the nouveau driver?
3. Ultimately I am looking for a tool that should be included in the installation screen that will:
a. identify your hardware: list the hardware detected on the screen b. highlight with color code any hardware listed that is not supported or poorly supported: in this case graphics drivers c. perform a quick benchmark test of your hardware: In this case I want the benchmark to tell me what capabilities my graphics card has. d. automatically recommend and set the best kernel parameters for a successful boot: if the graphics card needs nomodeset or modeset=0 or whatever I want it to do it for me.
Also I started a personal blog about this issue which I intend to compose into guide to assist others with this question. [URL] ....
My goal is to create a boot disc that will automate proper installation of graphics or other hardware for a system BEFORE installation. I would like to see this feature included in the Debian installation screen.
I've modified by mistake my menu.lst file. Both menu.lst and grub.conf are empty. how to fix this? Is there any command to quickly rewrite those files?
I try to write to a file "date > file" but Linux says 'cannot overwrite existing file'. I tried chmod 755 but still cannot write to the file. What should I do?
i have a duel boot of windows and ubuntu, but recently i got a virus, but this things is leach like in appearance. I tried reinstalling windows, then reformatting the drive and reinstalling windows but i still have this same virus? This is dead creepy for me because windows cant read any of the other partitions, which are all formatted for linux, in formats which windows does not have the capability to read. So i dont understand how this could have happened. There are many things that i am still to try -- including completely overwriting the MBR with a GRUB in case the virus somehow resides in there?? But i have decided to give up on windows from now, because, despite all the actions i have taken, it has failed me repeatedly. But having had these viruses 3 times, i have noticed something, the first time i had a virus was my fault, because i left my computer insecure.
After i formatted my HDD following that virus, i noticed i had 10gb of space robbed from me, disk utility believed i had a 160gb drive, but Gparted and everything else told me that i only had 149.7gb of space??? now after this virus - which logically couldn't have happened without someone directly attempting to tunnel my computer as i had so much extra security - i lost 6gb of space from my HDD?? Sounds odd?
THE QUERY: So i want to know if (from ubuntu) it is possible to do a secure format (similar to with a mac - were it completely overwrites everything, instead of just deleting the links) although, possibly i am not going back to windows, ever.
I've been trying for a long while to figure out why aptitude overwrites /etc/sudoers ? Each time I run
$ sudo aptitude safe-upgrade
my /etc/sudoers is reset. This is really annoying because I have it setup so that mythtv can shutdown and restart automatically. The line in /etc/sudoers that gets deleted is:
%mythtv ALL = NOPASSWD: /usr/bin/mythshutdown, /bin/sh, /usr/bin/setwakeup.sh, / sbin/reboot, /sbin/shutdown
When the line is missing my Ubuntu 10.04 does not shut down at all because of missing rights to do so. Does anyone have a clue why this is happening? I thought /etc-files were sacred for others than root, but it seems I'm wrong. Of course I have edited sudoers with visudo.
today when I tried to update my system, this message appeared. Code:E:var/cache/apt/archives/ubufox_0.9.1-0ubuntu0.10.04.1~mfn3_all.deb: trying to overwrite '/etc/xul-ext/ubufox.js', which is also in package xul-ext-ubufox 0I can't understand the effect of this on the system or how can I fix it.
