Pacman -Qdt and linux-headers

I was looking to clean up my system after installing a bunch of packages, so I ran pacman -Qdt and it spit this out:
pacman -Qdt wrote:[tyler@arch etc]$ pacman -Qdt
compiz-bcop 0.8.8-2
compizconfig-python 0.8.4-4
git 1.8.1.2-1
jshon 20121122-1
libidl2 0.8.14-2
libwnck 2.30.7-1
linux-headers 3.7.5-1
python-distribute 0.6.34-1
I got curious when I saw the linux-headers 3.7.5-1, so I ran uname -a to see my kernel and it spit out:
uname -a wrote:3.7.5-1-ARCH
My questions are, why is that in the cleanup list if it is the version I use?  Will removing it be harmful?  Or was it just installed to compile the kernel?

So I should leave it installed for later updates, if I don't want to have to re-download it every time something updates.  Correct?

  • [SOLVED]When pacman is updating linux-headers and linux, catalyst-hook

    Hello-
    I wanted this to be out there on the web so that people could find it.  I'm not sure if this could be considered a 'bug' for catalyst hook or for.. something, or if it is expected behavior.
    I ran pacman -Suy on my system today, and ran into errors about catalyst hook failing.
    Closer inspection indicated that it was trying to build based on headers of the version of linux that had just been removed, but the new linux headers hadn't been installed yet (after the hooks ran, then the linux-headers were installed)
    If you see this error during an upgrade, to resolve the issue simply run mkinitcpio -p linux after the install completes.
    Below you can see log/errors/progression

    Karol-
    That thread doesn't seem to be closed, and the thread it points to doesn't appear to really have a solution either, unless i'm missing something.

    I have this service running, but was concerned by the error message that i wouldn't have gui (and would have to drag out my laptop to do troubleshooting) upon reboot.  Next time I will let it be and make sure the service works correctly
    That said, I _did_ fix the distrust (or in this case non-rememberance) by running mkinitcpio -p linux.  Initial post has this detail in it.

  • Linux and linux-headers packages

    Hi,
    shouldn't linux-headers package has linux as it's depency? Currently I must roll back to the old kernel and that's why I should also manually track linux-headers package. As I understand there is litte if not sense at all in having headers different to the currently running kernel. You cannot have several parallely linux-headers packages (in order to build modules for different kernel versions) anyway.
    I thought I'll ask here, before submitting a bug report.
    Regards
    Roman

    Actually, that's not right. I have three different sets of Linux headers for ck1-kx, lqx, and the default. Each time each of my kernels upgrade, I recompile the fglrx module against each one with their own headers. Looking in /lib/modules/ seems to ascertain this.
    Also, there is a chance that using default headers for a non-default kernel could result in wrong behavior or info. For instance, compiling the fglrx module against linux-headers for the ck1 kernel does not work. I'm guessing not having the dependency simply means that you're able building modules for a kernel you may not have? I can see where this might be useful for those hosting a module for others without requiring the use of the corresponding kernel.

  • Glibc and linux-lts-headers

    Hi,
    I'm using linux lts in my archlinux installation, so I think I don't need linux-api-headers. Thing is glibc depends on linux-api-headers.
    Can I switch dependences to linux-lts-headers safely and replace glibc with a custom PKGBUILD from abs? That package is the only one stopping me to remove linux-api-headers.
    I'll appreciate your help.
    Thanks.

    really? I always thought linux-lts-headers and linux-api-headers are the same but for different kernels :-P.
    Thanks for clearing this up to me. I guess I won't need to modify anything then.

  • [Solved] nvidia-beta & linux headers

    Just installed nvidia-beta 310.14 & appears to be working fine.
    However, when i run:
    sudo pacman -R $(pacman -Qqdt)
    it offers to remove linux-headers 3.6.6-1.
    This seems like a very bad idea. As far as i know, they are in use:
    $ uname -a
    Linux archlinux 3.6.6-1-ARCH #1 SMP PREEMPT Mon Nov 5 11:57:22 CET 2012 x86_64 GNU/Linux
    Would someone kindly explain ?
    Last edited by flipper T (2012-11-12 20:29:38)

    It's required if you want to build kernel modules for example.
    If you don't want it to show up when doing "pacman -Qqd" just install it explicity.
    edit:  And take a look at the nvidia-beta PKGBUILD to see why it was installed.

  • [SOLVED] pacman -Qdt shows required packages

    I've used "pacman -Qdt" quite often but since yesterday it shows packages that it probably should not:
    autoconf2.13
    hal
    pm-utils
    pm-quirks
    hal-info
    dmidecode
    consolekit
    xorg-server-xvfb
    yasm
    If I remove "orphans" like pm-utils or hal, I will only know that they weren't orphans. For example pm-utils was explicitly installed and without hal Xorg/xmonad won't start.
    Can anyone explain to me what's going on here?
    Last edited by Markus00000 (2011-10-26 11:30:31)

    Thanks, yet I have no idea why Xorg/xmonad won't start after removing these orphans and is instantly fixed by installing hal and its dependencies.
    And also how pm-utils can be an orphan when I know that I installed it explicitly (pacman.log is with me here).
    And also why hal etc. did not show up before with -Qdt.

  • [solved] Questions about pacman -Qk and -Qkk output.

    I was looking through the pacman manual today to see if there was anything I could add to a some Arch maintenance scripts I've been working on and came across -Qk which, among other things, lists missing files. I ran pacman -Qk in terminal and found a few package installations were missing files. I reinstalled them manually check again and the files were no longer missing. The first package I saw that was missing a file was gnome-command-center for instance.
    So I really have two questions.
    1) Is it normal for packages to have missing files?
    2) Is it a good idea to reinstall these packages to replace the missing files.
    I then ran pacman -Qkk, and got even more disturbing information such as modification time mismatches and size mismatches.

    I'm assuming all of those are bad. "Warning" rarely sounds friendly, though for those files I've modified myself, such as passwd, shadow, and group, its okay. I assume I can fix msot of these by running # pacman -S {package}?

     Awk processes the output from pacman, splits it using [white]space[⁣s] as delimiter and prints only first field $1, which is the package name. Those reoccur if several files are involved, so just to be sure, I also used awks sort, maybe that could be skipped or alternatively sort command outside awk used instead. This sorted output gets fed into uniq, which outputs only unique strings coming from input. And that leaves you with the package list.
    Edit: I think those are whitespaces actually, which if I recall correctly include space.
    Edit2: So this might be better and certainly a little faster:
    pacman -S $(pacman -Qkq | awk '{print $1}' | uniq)
    # And this should be even faster, since the output pacman
    # delivers seems to be sorted anyway. Should you parse
    # something else, use my first suggestion instead.
    pacman -Qkq | awk 'BEGIN{ y=0; }; {x=$1; if (x == y){ next; }; print $1; y=x;}'
    Edit3: Out of curiosity I tested different methods measuring execution time with a input file consisting out of 1443 lines from pacman -Qkkq. Here are the results and the bottom is the test script.

     The awk internal sorting is the slowest method, but it seems it initializes longer, since there appears to be a constant difference between internal and external sorting. Uniq fed by awk is faster with smaller loops, but gets slower if repeated more often, yet overall remain fastest with the unique function I used within awk. It appears the more lines the input has, the slower uniq in comparison uniq in awk gets. Here is the testing script:
    #!/bin/bash
    LOOPS=('10' '20' '50' '100' '200' '500' '1000' '2000' '5000' '10000' '20000' '50000');
    rm /tmp/results*.log
    echo $(date), Generating input file;
    pacman -Qkkq > /tmp/input.txt
    for LOOP in ${LOOPS[@]}; do
    START=$(date +%s);
    echo $(date), Loops: $LOOP;

  • Systemd and Linux upgrade

    Yesterday I did pacman -Syu which included systemd and linux-lts upgrade together 
    After upgradation during the  building of linux image it gave error : udev module not found
    systemd replaced systemd-tools and libsystemd (udev was part of systemd-tools)
    now I am unable to boot , linux is dropping to recovery console and not able to find root partition

    All mention package was release on 30-08-2012

  • Atheros ethernet, compat-drivers & linux-headers version mismatch

    I just installed a new mobo (GA-H77M-D3H) which has an atheros ar8161 ethernet chip.
    The old mobo had a realtek ethernet chip which worked fine (but the RAM didn't).
    Arch (and other distros) doesn't have drivers for the new atheros one (there's a bit of a fight over its support in the linux kernel).
    I see many posts on how to fix this, but the solution isn't working for me yet.
    The solution seems to be to use the compat-drivers package. However, I'm having trouble building it (I'm not that great at solving these things yet).
    I am downloading compat-drivers from: https://www.kernel.org/pub/linux/kernel … ts/stable/
    (From the unzipped source, I am using ./script/driver-select alx)
    The problem is compat-drivers needs linux headers for my current kernel, 3.7.10-1-ARCH, but the version on the arch download page is Arch is 3.8.3-2 and I don't know where to find an earlier version.
    The download link I use for linux-headers is: https://www.archlinux.org/packages/core … x-headers/
    Note: I'm downloading on another computer as the one with no ethernet has no ethernet.
    "uname -r" gives me:
    3.7.10-1-ARCH.
    And I can't update without ethernet.
    The build error message is:
    make: *** /lib/modules/3.7.10-1-ARCH/build: No such file or directory.  Stop.
    So, my questions are:
    1. Is there anywhere I can get linux-headers for 3.7.10-1-ARCH? (and would this be the right way?)
    2. Can I force make to pretend I'm using 3.8.3-2? would this have any chance of success?
    3. Is there another way to fix this?
    Thanks.
    PS: It took me about 10 minutes to get through the forum register "captcha" due to bugs and my laptop not having accurate US time... I see lots of complaints about it online, so please fix (a regular captcha is far harder to spam).

    This works for me:
    1. Get latest kernel 3.8.3-2
    2. wget https://www.kernel.org/pub/linux/kernel … -u.tar.bz2
    3. Use https://backports.wiki.kernel.org/index … at-drivers documentation, but simply:
    - tar jxvf compat-drivers-2013-03-15-u.tar.bz2
    -./scripts/driver-select alx
    - make
    - make install
    - modprobe alx
    verify with lsmod | grep -i alx, if module is loaded.
    Note:
    compat-drivers-3.8.3-2-snpu.tar.bz2 didn't work for me with latest kernel 3.8.3-2.

  • Linux-Headers no longer needed?

    I noticed a few kernel updates ago that linux-headers was no longer needed and could be removed! I did not remove it since I was not sure. I thought I would have read something here on the forums about it, but unless I missed it (which is possible) I don't see it being discussed.
    I also manually searched for packages I could remove that were not needed and had no dependencies a few times over the past few weeks, and sure enough it still shows its not needed.
    Can I remove it and why is it no longer needed?

    Are you sure you're not thinking about linux-api-headers? linux-headers were called kernel26-headers before linux 3 came.
    linux-headers are needed by only a few packages, linux-api-headers however are required by glibc so you you still do need to have them installed.
    This is what I am looking at:

  • How to get linux-headers-3.6.4-1

    Hi forums,
    I have a new Arch install on an Asus G75VW that uses the x86_64 3.6.4-1 kernel. I've installed VMware Workstation by following the wiki, but when I run it it complains it can't find the kernel's C headers. I downloaded the "linux-headers" package but VMware Workstation doesn't accept it, which I assume is because the package gets "linux-headers-3.6.5-1" and VMware wants "linux-headers-3.6.4-1". Is this a correct assumption? What should my next step be?
    Thank you.

    Raynman wrote:The next step should be to update the rest of your system, in particular the kernel package, so that the versions match.
    Ok, thank you. I will review the wiki and do this.
    Raynman wrote:That is why people say you should always update before installing new software.
    I'm coming from Debian and the Arch Linux way of doing things is a bit different than what I'm used to. My first thought was I'd be able to download "linux-headers-3.6.4-1" through a package cache, but I haven't been able to find such a thing. Is the "linux-headers-3.6.4-1" package available at all, in an FTP or something?

  • 4500 and Linux Kickstart

    Hi all
    Since I changed to 4500 all my Linux kickstart install are having errors "some type of time out" the configuration is really straightforward, nothing strange.
    Any ideas?
    Thanks. 

    Actually, that's not right. I have three different sets of Linux headers for ck1-kx, lqx, and the default. Each time each of my kernels upgrade, I recompile the fglrx module against each one with their own headers. Looking in /lib/modules/ seems to ascertain this.
    Also, there is a chance that using default headers for a non-default kernel could result in wrong behavior or info. For instance, compiling the fglrx module against linux-headers for the ck1 kernel does not work. I'm guessing not having the dependency simply means that you're able building modules for a kernel you may not have? I can see where this might be useful for those hosting a module for others without requiring the use of the corresponding kernel.

  • Question regarding Oracle and Linux on VMware

    Hello,
    I carefuly read the paper on Oracle and Linux on Your Own VMware and I'm missing a point.
    The paper explains how to start a cluster on a single host in a single Linux VM on VMware.
    So, there are 2 instances of Oracle 10g DB on the same Linux VM inside VMware. What does allow that?
    Is it possible to run 2 instances on any (single) Linux box, or is VMware required? If VMware is not required, why this complication in that paper? If VMware is required, what does it bring that make running 2 cluster instances on the same host possible?
    Many thanks for your help.

    I have an oracle database (10.2) and I have a query that needs to compare data on the Oracle database to data on a MS SQL server DB. I'm using a DB Link between the two databases.
    How would I compare the date fields?
    I have a table that has a date as one of the fields and I need to restrict the records where the date is equal to the date on SQL, however the formats are different:
    My query is as follows:
    SELECT mkt_css_name,
    pmv_rqst_corp_id,
    pmv_rqst_source,
    'G',
    pmv_css_acct_no,
    eq.start_date
    FROM power_move@cmdt,
    enroll_que@tcis eq,
    marketer@cmdt
    WHERE eq.css_account_number = pmv_css_acct_no
    AND eq.requestor_type = 'P'
    AND eq.status IN ('A','P','G','S')
    AND eq.marketer_id = mkt_seq_no
    AND pmv_service_type IN ('G','D')
    And Pmv_Gas_Mktr_No = Eq.Marketer_Id
    AND pmv_received_timestamp= eq.enroll_date ;
    The problem is that the date is stored in Oracle in the following format: DD-MON-YYYY and in SQL as 'YYYY-DD-MM HH:MI:SSSSSS'
    for example: Data in Oracle would be 27-JAN-2012 and in SQL as 2012-01-27 00:00:00.000
    I get an error when I compile.
    How do you reconcile the formats when the syntax is different between databases?
    Thanks, SeanDATE datatypes do NOT have any "format"
    DATE datatype is stored in internal binary notation.
    use TO_CHAR to display, present & compare the DATE datatypes
