Ubuntu :: How To Do A Complete Uninstall/purge Of Grub2
Oct 15, 2010
When upgrading to Maverick I accidentally (yes, I know, my bad) installed Grub to my Ubuntu partition instead of to the MBR. It was already installed to the MBR prior to this. So, when I rebooted all I got was the Grub rescue console. I loaded the Linux image with a different boot loader on floppy instead, and proceeded to uninstall and reinstall Grub2 to MBR with
Code:
sudo apt-get purge grub-common grub-pc
sudo grub-install --root-directory=/mnt/ /dev/sda
sudo update-grub
However, on restart I now get the regular Grub console, but not the selection screen to select what to boot. This even though all Linux kernel images and the Windows 7 partition I have was found during the reinstall. So, seems I need to do a complete purge of Grub from both MBR and sda3 (which is the Ubuntu partition i accidentally chose on upgrade), and start over clean. Question is then, how do I do it, line by line from the terminal?

I'm having trouble with mongodb on debian. I'll start from the scratch: removing it.
Code: Select allapt-get autoremove --purge mongodb
Or:
Code: Select allapt-get purge mongodb
Or:
Code: Select allapt-get remove --purge mongodb
All end in the same way:
Code: Select all dpkg: error processing package mongodb-org-server (--configure):
 subprocess installed post-installation script returned error exit status 102
 Errors were encountered while processing:
 mongodb-org-server
 E: Sub-process /usr/bin/dpkg returned an error code (1)

I don't know if this is the right place to be posting, sorry if it's not. Basically, my issue is I installed a Chrome addon, didn't like the functionality, removed it, and it altered functionality of Chromium as a whole. So I want to remove Chromium and all its settings, then do a completely fresh install. Currently everything I've tried brings up all my old tabs and settings after the reinstall, as if I'd never done anything at all.

I am running Fedora 8. Each time I run a YUM command, I get the message that there are unfinished transactions, and to run yum-complete-transaction. Upon running yum-complete-transaction, it fails with this error. How can I remove this uncompleted transaction so I can finish the last one?

I went to remove FreeNX from my Ubuntu Lucid machine so I opened the terminal and typed: "sudo aptitude purge freenx" The command worked but when I used the command "locate nx" I got a list of FreeNX associated files (as well as nxserver files). Is it possible to completely remove a program from my system? I thought "sudo aptitude purge" would do it but apparently not. My only concern is that in the future if I decide to install something related to this program it will interfere and cause problems.

I'm running evolution 2.30.3 in ubuntu 10.10, with unity desktop, and I can't find the "purge" option for the tasks. As it disappeared or is it just me not finding it ? Also, while I'm here, I understand that unity is still in development. Where can I report the issues I notice while running it ?

Did a fresh install of 10.04 Desktop 86_64 this weekend. One of the first issues I noticed right away was that apt was not function properly. Say for example you install the packages tor and vidalia (assume I'm running everything from root). #apt-get install tor vidalia This command will check and install necessary dependencies, for example 'privoxy'. Now if you decide that you don't want to use privoxy and instead use polipo, you would probably feel inclined to remove privoxy. Well I found that apt-get autoremove, apt-get remove, apt-get purge WILL NOT remove all the files/directories associated with the package. You'll find that after running each of these commands, there will still be directories, scripts, etc. in /etc/init, /etc, and /etc/rc*.d. The only solution I've found to completely removing a package is aptitude purge [package].

Yeah, I use dselect. What can I say, I've grown used to it and prefer it to the more modern dpkg front-ends.Recently did a fresh install of Lucid Server 10.4.1 AMD64. There are some Standard packages that I don't need and I used dselect to purge them:
apparmor
apparmor-utils
friendly-recovery

I've just upgraded from ubuntu 9.10 to 10.04 64 bit, and everything went well except for the fglrx driver installation, which failed. I've checked the troubleshooting guide and tried to purge the drivers, with only partial success.
When i type dpkg -l '*fglrx*'
I get this,

I have searched around a bit and am having difficulty purging blockcontrol off my system. I am running Ubuntu 10.04 LTS i686 version. I have been able to remove some of the programs attached to blockcontrol but cannot remove blockcontrol. The synaptics package manager and console root access will not rip out blockcontrol. I want the entire Moblock/Blockcontrol set off the system.

I've setup two printers through a system running Ubuntu server that are shared with 30-40 users on our school network.
If the printers run out of ink or paper, they stop printing. The lazier members of staff don't proceed to recharge the ink or paper so when somebody does, hours later, the old jobs start printing again which the teachers no longer need or want.
I'd like to automatically have my system purge print jobs older than 1 hour. I'm running CUPS and sharing the printers through SAMBA. How do I do this?

I cannot uninstall Firefox, nor can I uninstall Chromium; one always stays if the other is uninstalled. For example, if I remove Firefox, Chromium will appear in its place and vice versa. This has got to be one of the weirdest bugs I've ever seen on Ubuntu! So, how can I uninstall both web browsers?

Are there some effective tools to purge the system of unused libs/pkg and other files?Till now I found localepurge (i do not remember where i found it) which does some trick, but I am sure there is a lot of other things laying around in Slack with no real reason to be there in some minimal installation.I found also unsuedpkg in google.code, but it does nothing on a fresh system.Such question won't rise if Slack team wouldn't be forgetting about Slack's significance in server segment and putting big efforts in "deskopisation" of it. I'd be happy seeing directories like xlibs/ and mm_stuff/ where all x related libs and multimedia related ehhh... files could go (I hope developers will see this message).

When I remove an application from YaST does it remove its config files too? If it does not, is there any command by which I can remove the config files for all the uninstalled applications?

I have a webserver WWW1 and a front-facing proxy PRX. I use SSH ProxyCommand to connect to WWW1's internal IP (private IP) via PRX (private+public IP). For some connections (not all) I see a network connection left open after I'm finished. These add up!
~/.ssh/config
Host *
ServerAliveInterval 5
ControlMaster auto
[code]....
On PRX, lsof | grep WWW1:ssh shows 124 open connections at the moment. On WWW1, the same command shows 243 open connections. There are similar open connections for WWW2, WWW3 etc.
WWW1 and PRX are Debian. Client connections are coming from a mix of Debian, Ubuntu and OSX10.6. I use Emacs Tramp but this has no special configuration (AFAIK) outside of my ~/.ssh/config. I'm concerned about running out of internal ports, and ideally I want these connections to clean themselves up without intervention. Ideally by configuring them to kill themselves off; failing that a command I can kill old processes with is fine!

writing a script that would keep the last three versions of tcpdump files.Due to the version of tcpdump I must use -C and cannot use -G. Using -C generates a new file after X MB's have been written and adds a .x after each new one. The problem is that these files are filling up the disk too quickly. The main part of the script will kill tcpdump when a certain condition is met but in the meantime I need to purge and only keep say the three last iterations of the dump file. So for example, there is dump.pcap.1, dump.pcap.2, dump.pcap.3, dump.pcap.4 and dump.pcap.5. I'd like the script to look at the datestamps and delete dump.pcap.1 and dump.pcap2 since the other three are the three newest files. comparing files based on dump.pcap.*, check the dates and only keep the three 'youngest' files?

I installed Fedora 15, which was my first real departure from Debian based Linux OSs. I absolutely love the new Gnome 3, and was able to configure F15 to work as I wanted it to. On rebooting I realized that there was no boot loader screen, that F15 just booted and didn't give me a choice as to which OS I wanted to use. Eventually I was able to configure grub to let me see the boot loader and added my old boot loader as a choice. This worked well, maybe not a perfect solution, but it worked. This weekend I installed LMDE (Linux Mint Debian Edition) to another HDD. LMDE uses grub2 and after the install F15 was not recognized.
Two questions: Is there a way for grub2 to see F15? or Can F15 be installed using grub2? I really don't mind re-installing from scratch.

I want to load grub2 from grub4dos.I want to load directly the grub2 core. I know how to load first 512 bytes from some patition by chainloader and load grub2, but what I need is to load directly grub2 core without passing by bootstriping code (first 512 bytes).So, my first boot manager is grub4dos, then I can load grub2 and later I load Ubuntu. But I think I have to edit --set-root
What I dont know is how.
In hdd 0,7 (sda8) I have Ubuntu 10.10 and /boot/grub/core.img is in sda8 (hd0.7)
I tried this way:
Code:
title grub2
find --set-root /boot/grub/core.img
kernel /boot/grub/core.img

This script simply deletes files older than a certain age (in this case 7 days) from a certain location; I use it to purge old backups nightly, and it works as expected:
# delete backups older than 7 days
find /mnt/backup/* -mtime +7 -exec rm -Rf {} ;
The problem is, every morning I get an email with an error message something like this:
find: `/mnt/backup/subfolder': No such file or directory

kmail is reporting that I have an unread mail in my inbox. There is not. Is there a way to "purge" or even to search for unreads? Apologies if this is a "google is your friend!" type question but I am in the middle of moving house, and Mrs Wakou would start throwing things at me if I started ploughing through MAN files and KDE's website.
