Ubuntu Servers :: Unable To Select Server Kernel With Preseed?
Jan 6, 2010
I'm currently trying to use preseed to build an ubuntu server box over the network. I'm using the netboot.tar.gz from the karmic main mirror. By default it installs the standard kernel (linux-2.6.31-16-generic), and I want to use the server kernel (the metapackage linux-server which should install linux-image-2.6.31-16-server). I'm using a minimal build:
Code:
tasksel tasksel/first multiselect minimal As far as I can see all the other preseed settings are close to defaults. I've tried setting both of the following lines (separately and together) with no effect:
Code:
d-i base-installer/kernel/image string linux-server
d-i base-installer/kernel/override-image string linux-server
Once the machine is built, if I run:
I would like to create an unattended install ubuntu 10.10 cd. I have followed the ubuntu [URL].. on creating the preseed file, however, I can't find any useful tutorial on how to set the kernel parameters to perform an unattended install using my preseed file.
Is there a way to select a second installed OS on a home server system without display and keyboard? I am putting together a home server (for mail, storage, media streaming) using an Atom-based Ubuntu Server 10.04 on a 4 GB intern flash drive and 2 hard drives for data storage, but no display or keyboard. I want to make periodic full backups of the system (flash) disk and use a second OS (installed on a partition on the hard drive) with a graphical interface (e.g. Xbuntu or PartImage) for maintenance purposes. I can connect remotely (from a Win7 or a Linux computer) to the X-display once the second system is running.
a) how can the second OS be booted on this server without keyboard? Is there a way to tell Grub2 to look at some hardware switch (or file) for the menu selection? The board has a serial and parallel port so I could wire up a switch to some pin of one of these. Also external USB connectors are available on front and back. Or can Grub2 read its default OS choise from some simple file, easily to change from a shell command of the eBox webbased system control internface?
b) I assume the second OS is needed to make a complete backup of the server OS on the flash disk. Can the backup be automated? (i.e. switch to second OS, backup, reboot first OS)
Am carrying out installation of CentOS-5.5 on a Sun fire X2270 server using PXE. The installation starts well but on getting to the keyboard type the installation halts. I have plugged in a USB keyboard unfortunately, am unable to select the keyboard type even on reboot as the keyboard is non-responsive.
[Note: I'm typing this entire thing out. It probably isn't 100% verbatim. And I am using an older version of the kernel because 2.6.30.9.96 was not behaving either.]

Never thought much about it until now a but is it possible to get the desktop kernel at install with 11.3 DVD ? I always get default-kernel and have to do the kernel dance to get the desktop-kernel I prefer. I'm familiar with the multiversion = kernel-desktop and methods to retain different versions. Just wondering.
I have a "Chicony 1.3M UVC Webcam (Asus G1S notebooks)" webcam, which is supported by Linux UVC [1]. However I'm unable to find the kernel parameter that I should select to compile my kernel to support this device.
I've recently upgraded from Ubuntu 9.04 Server edition to Karmic Koala 9.10 server.Earlier when I ran uname -r it showed: KernelVersion-serverNow the current version I've upgraded to shows 2.6.31-20-generic-pae.Should the Ubuntu server edition be using a generic-pae kernel?
On my system (Ubuntu 9.x -> 10.x) I have always had the problem of not being able to select the edges of a window in order to change the window size. It seems that the 'hot' zone, which defines the window border selection area, is only 1 pixel wide. I find it very difficult to position the mouse pointer over this zone. Even if I am successful (which usually takes more than 20 tries), as soon as I begin to depress the mouse button, the merest movement causes the pointer to move off the 'hot' zone - and selection fails. The only work-around I have found is to select a corner point of a window -which seems much less sensitive - and then drag the window border in either a vertical or horizontal direction, rather than diagonally. But this is counter-intuitive and unsatisfactory.
I am an extremely new Ubuntu Server user. I am trying to install NFS on a new Ubuntu Server 10.10 installation. When running the command sudo apt-get install nfs-kernel-server nfs-common portmap, I was previously getting the message:
E: unable to locate package nfs-kernel-server
I'm sure I don't have the correct sources for installation, I just don't know source I need to add.
I'm having a problem connecting to my server with ssh.I'm running the latest Ubuntu 9.10 32-bit server, inside a virtual machine on a Mac (VMware Fusion 3, running on OS X 10.6.2 with 64-bit kernel).I've set up a network interface (eth2) to act as a host-only network between the virtual machine and the host.I can ssh into the server from my Mac when I type in its IP address ssh root@[IP address] BUT, I can not connect to the server.do I need to open a port with ufw? or configure something else in the ssh settings?
I have just tryed to install Ubuntu 11.04 onto a USB to install on a netbook. I used the software recomended to prep the USB and booted to it.
In the opening menu where you can select to install on a partition I am unable to press enter, it seems to just reset the menu. The keyboard seems to be working fine because I can use the arrow keys.
I have been unable to find a solution to this problem online, all I have found is this simular issue, with no resolution.

The netbook I am using is the Samsung n220 which apparently works well with ubuntu.
I am attempting to put a SystemRecoveryCD ISO onto a USB drive by using a shell script that is bundled with the ISO file (usb_inst.sh). When I run this script, I am presenting with a dialog box with a blue background (see attachment) with two options: <OK> and <Cancel>. I am able to switch between the options by using the arrow keys and Tab, but if I try to select an option by pressing Enter, O, or C, a new terminal line appears (as in the attachment), preventing me from selecting anything in the dialog. I feel like I'm not doing something extremely obvious;
I'm using Karmic with Grub 2 (1.97b4) I have this strange problem going on and believe it might be a bug so if no resolution will file it on Launchpad. Whats happening is this:when I installed Karmic fresh a couple of months ago I never did anything with customising the Grub splash screen. I just stuck with the boring black/white and if I wanted to got to Memtest or my little used Win XP partition would just hit the down arrow when the Grub Splash appeared and go there.A couple of days ago I decided to add some custom colors to the splash screen as outlined in the Grub 2 documentation. I did this to both my desktop (Acer Aspire L100) and my laptop (Compaq) Everything looks fine except for one thing. On the desktop if I hit the down arrow (or any other key) it immediately boots the first option which of course is Karmic. It should have paused the timer and allowed me to scroll down. What this means is I can only boot Karmic at this time. This is only happening on the desktop!
I am fairly new to ubuntu server, I want to setup a tftp server to mount a new kernel in a DaVinci platform. I was following the guide in this page [URL]..docs/linux_tftp, but accidentally I remove the xinetd.conf file. So I think that maybe removing and reinstalling xinetd the problem will be solved, but instead of that I can't completely remove xinetd and the follow message is print in the terminal
Removing xinetd ... invoke-rc.d: unknown initscript, /etc/init.d/xinetd not found. dpkg: error processing xinetd (--remove): subprocess installed pre-removal script returned error exit status 100 invoke-rc.d: unknown initscript, /etc/init.d/xinetd not found. dpkg: error while cleaning up: subprocess installed post-installation script returned error exit status 100 Errors were encountered while processing: xinetd E: Sub-process /usr/bin/dpkg returned an error code (1)
with that problem I can't start the service or stop it, I am blocked in the configuration of tftp server.
I was installing Ubuntu Server 10.04 last night, and the select software to install step failed. I tried to start over from scratch, but then the partitioner wouldn't load. Has anyone else seen this before?
I want to configure a remote internet facing server as git server. I would like to restrict access to the server to a few systems (access is restricted to select computers, not users). I first thought of using ssh key, but the key can be copied to another system hence that alone is not sufficient. I am having a dynamic IP, so simple IP based firewall blocking is also not possible. I was thinking about the possibility of using both SSH Key and IP based access. Is it possible to update the firewall rule whenever my ip gets changed?
Here's the text from the serial console before I rebooted:

My root server is using CentOS release 5.2 (Final), kernel 2.6.26.5-rootserver-20080917a, SMP, 64-bit This Oops happened yesterday and before that it happened on March 14th of this year, and before that on January 31st of this year, so a repeating pattern. On the January 31st Oops, I just rebooted. On the March 14th Oops, I reformatted the two swap partitions as follows: mkswap -c /dev/sda2; mkswap -c /dev/sdb2 On this last Oops, I turned off the swap for 24-hours, then decided to turn it on again after doing the above mkswap again. During the previous uptime, I had dumpcap packet capture running, but this last reboot, I'm not going to run it.
I am using MonoDevelop with SQL Server whenever I try to do use the Select method on the Datatable object the performance really detoriates it is 3 times slow than it is with .Net. Are there any work arounds?
I had downloaded Debian 8.2 (Jessie) below files all are checksum passed. During installation after the 'Select and install software' stage the process halts and unable to proceed further.
I get the following error. ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Installation step failed An installation step failed. You can try to run the failing item again from the menu,or skip it and choose something else. The failing step is: Install the system. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
I just updated my system, not sure which package may have caused this, here are the outputs:

just installed Fedora 15 on my system alongside Ubuntu 10.10 on My 500 GB hard disk.However on starting the computer the Fedora 15 partition gets loaded automatically. How do I access my Ubuntu 10.10 partiion? I want to have a choice at start-up which OS to use. On my previous computer when I used to have Windows and Ubuntu,a menu used to appear asking which operating system to load.
I am a total noob in the process of trying to build my own server. I installed Ubuntu 10.10 but when I did that I didn't have the computer hooked up with an ethernet or have any internet connection. During the installation process it was unable to set up DHCP, so I figured I would just do that later, somehow.
Anyways, I recently hooked up an ethernet cable from the server to another computer, which has internet.
I've been slowly working my way through the Server Documentation and am on the Networking chapter. It has given me the commands to install wireless-tools, ethtool, dhcp3 server and I've also tried to install gedit. Every time it gives me the error: E: Unable to locate package XXX
When I ran the sudo lshw -class network command I find that it recognizes both an ethernet interface as well as a wireless interface(my wireless adapter). BOTH of them say *-network DISABLED.
My goal is to enable both of those, but I am assuming I need to be able to locate the packages first. I installed the server edition using a USB pendrive. I still have the files on the pendrive, but I don't know how to make the server locate those files. I'm guessing it wants to access the installation files to locate the packages to install.
I currently have to connect to my new samba fileserver using servernameusername instead of just username, if that makes sense(!) I need this to be simplified, as I've had it before on a previous machine, as one of the devices I connect with has a virtual keyboard without a backslash!
I am trying to setup a mumble server on Ubuntu Server 10.10. I have downloaded/installed all of the necessary files and configured my router to open up the necessary port (64738 ). However users outside of my network are unable to connect to the server (get Timeout error). Also to add, I am fairly new to using linux/ubuntu.I made a post on reddit where you will find more information regarding my problem: [URL]
I recently decided to convert my old NAS gox from Gentoo to Unbuntu Server. For reasons that I do not understand I cannot install 10.04 or 11.04 on it. I've downloaded both the i386 and the AMD64 ISO images to the same machine, burned the the image on the same DVDRW drive onto the same CDRW disc but when I try to install on the D945GCLF board, it consistently fails at the same step - Unable to install base system.
The ISO image all indicate a good MD5 sum and I've burned the ISO image at the slowest possible rate. I've even tried moving the image onto a USB drive and installing from it - same error. The D945GCLF has parallel and serial ports disabled; I'm using the SATA drive for the OS and installing from a USB CDROM drive
I appear to be unable to select individual updates for installation anymore from the Yast Online update screen. I use this to install updates manually on 11.1. But everytime I think I've chosen an update to install, all the updates listed get installed, and not just the one I've chosen. For example I just chose a "Fuse security update" to install and clicked the "Install" button. Nothing further happens until I click "Apply". Then all patches listed under the "All available" listing get applied. How do I just apply the patches that I want to ?
I have done a fresh install of Ubuntu 11.04 on my oem intel machine.After the installation,the screen resolution is stuck at 800x600.I am unable to select a higher screen resolution.
I switched our main fileserver to new hardware running RHEL 4 Update 8 yesterday. Post the switch my users are finding that the text in the boxes on taskbars at the bottom of their desktop screens no longer truncates but spills over onto that of other boxes, making them extremely hard to decipher.
All our desktops are RHEL 4.8 too. Also, I'm only able to select PNGs as desktop wallpaper - JPEG backgrounds just appear as plain white when selected(!) Has anyone seen this before and knows of a fix?
