[Bug 241368] Re: remove old kernels from grub list

2012-05-21 Thread Tom Chiverton
I've had discussions with people on the debian-mentors IRC group. 
There is not much prospect of my approach in the PPA working automatically. The 
best it can do is tell you the command to run (DUMMY_RUN left as the default). 
It you are in the habit of running sudo apt-get update;sudo apt-get upgrade 
from the command line like me, that is good enough.

A real fix is being addressed in

Sound very technical but how do you do any of these things. What does  sudo 
add-apt-repository ppa:bugs-launchpad-net-falkensweb/remove-old-kernels mean?
Its all meaningless to new users. I now have 4 pages of old kernels on my 
laptop with windows at the bottom of course.
What is a grub list and ho do I edit it?
How do I remove the old kernels?

These are the sort of questions that need simple answers for people like
me.

Good job that I only use my laptop for playing games on.

Title:
  remove old kernels from grub list

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  Binary package hint: linux-image

  This is a bug for new user confidence. So far Hardy has updated the
  kernel 3 times, which means 7 Ubuntu options on the grub list (3
  kernels, 3 recoveries, 1 memtest).

  A beginner will definitely be intimidated by this huge list of grub
  options. When I made the jump from Windows, after the first kernel
  update, I was really worried that I would make the wrong choice. No
  explanation is given in the grub menu, and the only difference between
  the options is one number. I thought this new option was a completely
  different version of Linux (not just the kernel), and all of my data
  might be on the other option. An unexplained option on the grub boot
  menu list adds anxiety, which doesn't help Bug #1.

  There are two general ways to fix this:

  1) Commenting out the options in the grub list. This is a simple fix,
  but it doesn't clear up the space taken by the old kernels. There is
  also the possibility that grub updates will reload the list, bringing
  back all of the options. You would have to make sure any reloading of
  the grub list also makes sure the old kernels stay commented out,
  which makes this a trans-package fix.

  2) Actually removing the old kernels. This clears up space, but runs
  the risk of removing a stable kernel when the new one causes problems.
  I agree that at least one old kernel should be kept just in case the
  new one doesn't work. However, that would still mean 2 kernels showing
  up on the grub list, which will still intimidate casual users.

  ---

  If there is worry about adding an prompt for the user to choose, there
  is already one that appears when the kernel is updated: the restart
  notification. The update manager lets users know they need to restart
  their computer, and there is plenty of room for a short notification
  that the new kernel is at the top of the grub menu list.

  So, my proposed solution:

  1) When installing a new kernel, mark for removal all but the current
  kernel (plus the one that's going to be installed). That way, if the
  new kernel doesn't work, the user can just use the previous one. Also,
  if more advanced users want to keep older kernels, they can simply
  uncheck the mark for removal of those older kernels.

  2) Include a sentence in the restart notification that says something
  like, Your updated Linux kernel (x.xx.xx-xx) will be added to the top
  of the Grub list. (What's a Linux kernel?) This is so casual users
  won't get confused when they restart and now see two versions of
  Ubuntu. The What's a Linux kernel part should have a link to a small
  help that explains what it means. The help file shouldn't have a in
  depth explanation about kernels, just info saying that this isn't a
  new version of Ubuntu, just a new version of the underlying hardware
  interface, so no data will be lost.

  3) After a successful restart (or several successful restarts),
  include a notification that says something like, Your current Linux
  kernel (x.xx.xx-xx) appears to be working well. You can remove old
  Linux kernel versions to clear up space (XXX MB). This will also
  remove those old versions from your Grub boot menu list. You can do
  this anytime by removing the following packages via Synaptic: A, B, C
  [Remove old versions now] Similar to the update notification, it
  would be confined to the Notification Area, and would pop up only when
  the user clicked on it. The Remove old versions now is a button that
  the user can click. This is so the user can simply dismiss the
  notification if they want, but still be informed if they want to
  remove the packages later.

Quote I'm using Ubuntu 11.10. GNU GRUB version 1.99-12ubuntu5 removes
old kernels from the grub list and shows: Previous Linux versions

Is this version soon to be released as a general update?

I now get two screens full of previously release messages, and have no
idea from reading all the 50 odd comments above what anyone is talking
about and whether its possible or not to remove them..

Most Ubuntu users may be what are called Geeks (no criticism
implied), but I am no longer one of these. I just want to switch my
computer on and select Windows or Ubuntu, without having to know the ins
and outs of the code that runs the OS.

I agree that this bug should be solved via a sub-menu system (like Bug
#540452). However, Tom Chiverton's script is very useful in keeping a
lid on the disk space taken up by updated kernels. Perhaps a combination
of the script that keeps the latest two kernels and puts one in a sub-
menu, leaving only the most recent at the top level grub list.

computer-janitor was originally designed with this as its single most
important use case.  I believe ultimately it's due to be subsumed into
software-center, at which point it would be in a tool that people
actually run rather than hidden somewhere in the menus; it seems that
that ought to help.

[Bug 241368] Re: remove old kernels from grub list

2010-09-02 Thread Tom Chiverton
Correct, the script currently does not run the command, instead printing it out.
It is my intention to change this to run the command once it's been stable for 
a while (and several kernel updates). In the mean time testers can duplicate 
the line
  echo sudo apt-get remove $PKGS_LIST
and remove the echo :
  sudo apt-get remove $PKGS_LIST
to have the suggestions happen automatically. 
This *should* be safe, but be aware of the limited testing to date.

Yes, the user will see multiple kernels (at least two if using last-
good-boot). The default settings for Grub, however, mean the latest one
will always be selected.

Your suggestion to append (Recommended) is a good one though- open a
new wish list item.

[Bug 241368] Re: remove old kernels from grub list

2010-09-02 Thread Tom Chiverton
Kangarooo and Srinath: Ah ha, I get what you are on about now. My test
system here doesn't have that package because of the same issue :-)

This is now fixed. The script should now only ever remove packages that match 
this pattern
linux-image-|linux-headers-|linux-backports-modules-
*and* show up in the 'dpkg -l' output as a 3 dotted number followed by a dash. 
This should prevent removal of the package that triggers updates (as it shows 
up as a 5 dotted number)

The running kernel is now never removed either, just as with the last-
good-boot kernel (if present).

There is also an option to run the command.

I've also tweaked the output:
$ ./remove-old-kernels
/etc/kernel/postinst.d/remove-old-kernels:
Reading system config file /etc/remove-old-kernels.conf ...
Found last-good-boot, 2.6.32-23 will never be removed
Current kernel 2.6.32-24 will never be removed

Will remove packages for 2.6.32-21.32
Suggested command is ...
sudo apt-get remove linux-image-2.6.32-21-generic
$

if I change my number to keep:

$ ./remove-old-kernels

Suggested command is ...
sudo apt-get remove linux-image-2.6.32-21-generic linux-image-2.6.32-22-generic

2010-09-01 Thread Kangarooo
@Tom Srinath means that his kernel witch doesnt work is the newest
thats why he wants to remove it.
BUT removing newest with commands makes image-kernel removed
BTW if image-kernel is also removed then no new updates come.
so when script will work fine for reason to remove old kernels then
next step version witch also offering choose latest but without
removing image-kernel would be good. maybe somone will find how to
remove that with command line. im now off and going away for 4 days.
then ill find if no one finds till then.

when ill come back ill check V3 and post thouse outputs.

[Bug 241368] Re: remove old kernels from grub list

2010-09-01 Thread DanielRoesler
I'm glad people are discussing and proposing fixes to this bug, and I
have some questions.

This script, from what I understand, creates a suggested command (but
doesn't run it) to remove all but the last good boot kernel and the
highest numbered kernel, right? If not, please clarify.

I worry that this script doesn't address the original problem of a
confused new user after updating. First, I'm assuming this script would
automatically run after an update, and it would also be changed to
actually run the 'sudo apt-get remove ...' command, right?

Second, when the user reboots, there are still two kernels to choose
from in the Grub list. Plus, there still isn't any indication about
which one to pick. How can we explain, either on the Grub menu or before
the user reboots, which one to pick?

Perhaps we could change the listing for the latest kernel to be appended
with an (Updated) or (Recommended) or something?

I think you refer to this line:
  new=`dpkg -l | grep ^ii | grep $ver |grep linux-| awk -F' ' '{ print $2 
}'|xargs`
which identifies all the packages involved with a particular kernel version.
In this case, searching (with grep) for linux- instead of linux-image- has the 
same effect, unless you see otherwise (in which case, please show the commands 
as well as the filtered and unfiltered (before and after grep) outputs).

@Kangarooo
I don't believe this script should be interactive. My use case is that it Just 
Works, on unattended servers or 'Joe Sixpack' machines where we can't or don't 
want to bother the user with something they do not care about and don't 
understand (see #16). This is how other distributions such as RedHat work.

last-good-boot may need enabling in /etc/default/kernel-helper-rc or
something else - please ask on the forums for details.

Sorry to have broken your upgrades. You should simply be able to
reinstall anything you uninstalled, again, please ask on the forums for
details as it's kinda off topic for this bug.

Kangerooo: If you've accidentaly (as the script mistakenly suggested)
removed the mose recent kernel, sudo apt-get update; sudo apt-get dist-
upgrade should reinstall them.

Jeff: Spot on idea with the number being configurable (from a file in /etc/). 
Would you want a list of known good or just one? Would simply using the one 
recorded by last-good-boot (i.e./boot/last-good-boot/version ) work for you ? 
Actually, the script should probably honour that regardless as a safety net to 
stop other people having Kangerooo's problem.

I think since its its not know for all witch is good kernel then i think
Jeff sugests that its choosable witch one to ignore. That means another
terminal gui version with choosing witch to ignore
Example
./removekernels
1 2 3 4 5 will stay 6 7 8 will be removed do u want to change that? [Y/n]
Y or enter
kernel1 kernel2 kernel3 kernel4 kernel5 kernel6 kernel7 kernel8
1 or a   2 or b   3 or c   etc
if more then 10 (1-0) then   moves to next (or maybe make kernel chooser
to allow to choose from 10 latest installed that will be ok couse al
nonworking user have been already revomed
so 1 4 6 7 8
with Enter accept
1 4 6 7 8 will be removed
Thank you for using kernel remover! Have a nice 1337 day :)

@Tom no update and dist-upgrade doesnt install update of whats been removed.
Since thouse image-generic and kernel-something-generic packages without

[Bug 241368] Re: remove old kernels from grub list

2010-08-18 Thread Jeff Craig
It might be nice if this could be somehow configured as well. The
following configuration options seem potentially useful:

Keep X most recent kernels. Defaulted to 2, this should keep a 'known
good' kernel, and the new one, but remove older ones.

Kernel Whitelist: Never delete this kernel revision, this would allow me
to keep a 'known good' when I'm running an Alpha version of Ubuntu (as I
am now).

This is a *huge* problem on SSD devices, as my netbook only has 16 GiB
of space, and 2.4 GiB were consumed with Kernels (I removed a bunch, but
I can still remove some more).

[Bug 241368] Re: remove old kernels from grub list

2010-08-13 Thread Tom Chiverton
I'm also attaching a newer version which outputs more about what it is
doing and why, please post the whole of the new output. It's harmless to
run directly from the console (still).

[Bug 241368] Re: remove old kernels from grub list

2010-06-30 Thread Tom Chiverton
The solution seems complicated, with all the prompts and so on. This
*will* confuse users, and is something that can easily be hidden.

For casual users, the current kernel will be stable, and updates will only be 
for security. 
We should keep the current and new kernels by default (so if the update does 
break anything, the user can recover). 
Power users need to easily change this limit.
I suggest a simple script like the attached (but should get 'number to keep' 
from /etc/defaults/ etc). It can be easily triggered via a link in 
/etc/kernel/postinst.d/ - simply sucking up all the users disk space with limit 
(as at present) is not a solution, nor is expecting users to under stand what a 
kernel is or what is a 'good number' to keep around.

De-duped from bug 132311 because that bug is really about running out of
disk space breaking upgrades.  This is a different issue which might be
related but isn't a duplicate.

The growing list of kernels also makes it difficult to dual boot chain-
loaded operating systems like Windows or DOS. Wiki page
https://wiki.ubuntu.com/KernelTeam/removing-old-kernels has a good
solution with saving the last-known kernel.

[Bug 241368] Re: remove old kernels from grub list

2009-09-02 Thread Lasse Kärkkäinen
Completely removing the old kernels (rather than just removing from GRUB
menu) is necessary because the modules use a very large amount of disk
space (especially so when running on SSD). Constantly increasing disk
space usage is precisely the kind of thing that people hate in Windows.
Apt could solve this issue nicely, but only if Ubuntu actually removes
the unneeded old versions.

2009-07-15 Thread kernel-janitor
Hi diafygi,

Please be sure to confirm this issue exists with the latest development
release of Ubuntu.  ISO CD images are available from
http://cdimage.ubuntu.com/releases/ .  Please then run following command
from a Terminal (Applications-Accessories-Terminal).  It will
automatically gather and attach updated debug information to this
report.

apport-collect -p linux-image-`uname -r` 241368

Also, if you could test the latest upstream kernel available that would
be great.  It will allow additional upstream developers to examine the
issue.  Refer to https://wiki.ubuntu.com/KernelMainlineBuilds .  Once
you've tested the upstream kernel, please remove the 'needs-upstream-
testing' tag.  This can be done by clicking on the yellow pencil icon
next to the tag located at the bottom of the bug description and
deleting the 'needs-upstream-testing' text.  Please let us know your
results.

Thanks in advance.

This bug was reported against the linux-meta package when it likely
should have been reported against the linux package instead.  We are
automatically transitioning this to the linux kernel package so that the
appropriate teams are notified and made aware of this issue.  Thanks.

** Package changed: linux-meta (Ubuntu) = linux (Ubuntu)
