Debian :: Delete An Unused GPG Key?
Jun 1, 2010
I recently installed an application called DeaDBeeF. I added the GPG key, as well as the repo in my sources.list file. I've decided to stick with Audacious, so I did an "apt-get autoremove deadbeef" to remove it and all of its dependencies. I also edited my sources.list file and removed the line pointing to the repo in which I got it from.
Now my question is, how should I remove the GPG key, if I don't use the repo or application anymore? I don't want an unused GPG key sitting on my Debian if I'm not using the repo anymore.
I've tried reading the man pages but I can't seem to get it. I've tried the following command but it doesn't seem to work.
sudo apt-key del http://hadret.rootnode.net/debian/duckbill.key

I recently moved to a new machine, and I copied my entire home folder across. This included lots of hidden (starting with '.') folders, and in many cases they are config folders for packages which I have not installed on the new machine. They are taking up space, so I would like to delete them, but to go through manually and figure out which ones I need would be very laborious. Is there a way to find, and perhaps delete, config folders for packages that are not installed?

I am using LVM2 and have shrinked my /home partition and extended my / partition but I'm not sure if I used all the free space when growing my / partition. How can I find out? I prefer using the terminal if there is a graphical way to do this but I would like to know both ways if there are two ways.

I have Ubuntu Meerkat (10.10) running on an Inspiron E1505. I have it setup for dual boot with Vista. I installed Kubuntu on top of Ubuntu and now have a blue Kubuntu system loading screen where it used to be purple.
I've installed a lot of programs, most unnecessarily, so I'd now like to get rid of ALL of the unnecessary programs and associated packages or dependencies. I'd also like to get rid of KDE, and any Ubuntu packages I never use.
Is there a quick and relatively easy way to do this?

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.

I've been running fedora 12 for a few weeks now and I was wondering how to clean up all of my unused files. I have accumulated quite a bit of software in the form of updates and downloaded packages since starting and I can only assume these are going to continue to build. I have rpmorphan and it lists all of the programs I'm not using but I'm wary of it because it lists WINE as one I haven't used but I use it everyday to play a game. I'm afraid I'll erase something I need, but I'd like to keep my system as clean and slimmed down as possible.

Is there a way that I can clean up unused packages that came as a dependency, but their dependant removed so that they are idling?

I have no problem with resolving dependencies on my own, but when I uninstall a programm, how could I keep track of the dependencies, thus remove them?
Is there a possibility to store this information in the /var/log/packages files, or better yet, is it possible to include the dependencies in the the .tgz's, so a 'removepkg' would get rid of them as well?

I have a CentOS 5.3 x86_64 system setup as a file server, backup server, and iSCSI target. The physical machine has six hard drives, two of which (bay0 and bay1) are 1TB disks in a RAID1 mirror. Therefore, CentOS is installed on /dev/sda. My question is this: how can I format and mount the large portion of sda that's not in use right now? Here's some more info:
Disk /dev/sda: 999.6 GB, 999653638144 bytes
255 heads, 63 sectors/track, 121534 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
[code]...
As you can see I've got about 1TB of space on sda. However, when I look at my df -h command and my LVM management what I find is that I've got:
root / filesystem = 8GB and is under Vol00
swap = 2GB and is under Vol01
/var = 2GB and is under Vol02
Sounds like I have a ton of space on sda that I'm not using. It also looks like I'm using LVM, but I'm not familiar with LVM nor am I really comfortable with how I can use the rest of the 900+GB I have available on sda. how I can format and mount the rest of the free space on sda?

I've been installing and uninstalling some stuff, and I would like to know if there was a way to see if I have yet to uninstall some unneeded packages. There was a way of doing this on Ubuntu via the Computer Janitor. Is there any way of doing that on Fedora 12?

I just installed Fedora 12 in a laptop with a big hard drive and used LVM for it. The thing is that I used just a fraction of the LVM total size to create the "/" partition and decided to leave the task of creating the other partition (the data partition) with the rest of the LVM space after F12 got installed. Unfortunately I found that Gparted is apparently unable to perform that task of creating a new partition in unallocated LVM space. Is there any way I can create a new partititon in that unused LVM space?

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 seem to have a strange problem with disk usage on my linux partition. I just upgraded my 10.04 to 10.10 and I'm not sure if this was there before.My nautilus tells me that I have 1.4 GB free on my linux partition. My partition editor (GParted) tells me that 79.31 GB of my 81.38 GB is used, and I've 2.08 GB free. There's no way I've got that much stuff on my linux partition, and to confirm it, I ran the Disk Usage AnalyzerApplications/Accessories), and the total size of everything on that partition amounts to much less than 10 GB.
I've tried deleting all my trash (both root and user trash) and I looked at all the folders trying to find any suspiciously large ones to no avail. I thought it might be some weird bug, but removing some files, added the correct amount of space to the free space detected by nautilus. I have no idea what eating up my disk space.

I wondering does the evolution-alarm-notify and evolution-data-server-1.4 would remove from the system monitor or just leave them alone. I didn't want to touch them that would cause system diseaster, can you please confirm for both if say yes to remove that will be good safe.. I am running older version of Ubuntu 5.10 on my lappy.
My firefox browser takes too much memory that runs very slowest and I need to cut down the both program list above or what I need to remove some other program in the system monitor.

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.

Does any body have a script handy to detect unused disks on a Linux Server? I have a bunch of RHEL 4 and 5 Servers with a number of unused EMC disks hanging in there. I just want to make use of these disks or return these disks to the SAN Pool after confirming that they are unused.

My aging laptop has a key broken - the D key. To replace the keyboard is too expensive, not worth spending �100 on old hardware. I sometimes use an external USB keyboard just to type D but being laptop is not always convenient. My question is how to bind key letter D to something else, be it a key combo or one of the unused/unneeded keys?On this italian laptop keyboard there are some keys i never use like Mac style right click menu button next to AltGr or home/end keys i could spare for this.

How do I reset all the passwords and regain complete control of my system

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).

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?

I accidentally removed windows when I was installing debian so I would really love to get rid of it because its not supportive with a lot programs and games I was using on windows. I heard there are ways to remove it like that but I dont know what I left with if I success and delete debian, what I have without any operative system and could I use my copy of windows 7 from my disk?

I would like to delete some files stored in the personal directory, say .adobe, .macromedia, .xsession-errors, on every start-up or shutting down. I can do it with cron but I would like to learn different (simpler) options. The thing is, I haven't been able to input the proper terms in a search engine. Note that these files must exist in their default location during the session. This is, I don't want to make them links to /dev/null or move them to /tmp.
