Re: How to uninstall a kernel and *all* of its dependencies?
2009/10/23 Klistvud quotati...@aliceadsl.fr: Howdie, fellow Debianites! My daily question for today: this morning, another kernel update was proposed to me by the Gnome update applet. As I already have three kernels on my Lenny system (the 2.6.26-1-amd64 and 2.6.26-2-amd64, as well as a a backported 2.6.30- bpo.2-amd64), my grub startup list is beginning to look a bit clobbered. How can I go uninstalling some of the unneeded kernels (particularly the backports one which didn't meet my needs in the end) and make sure that *everything* that got installed by their respective packages -- or built against the particular kernel, such as my wireless and graphics modules -- gets uninstalled as well? What is the Debian way of finding which packages will be obsoleted by uninstalling a particular kernel, so that I can prevent cruft from building up? And ... ehm ... yes, well, I admit, I'm using Synaptics ...

That's definitely not a right way. Generally, modifying system files manually is usually a bad idea. Almost every file in your system (I'm talking about /usr /lib /boot etc, not /home or /var/log) belongs to some package. If you want to remove it - it's better to remove a whole package. When the package is removed you can delete it's reverse-dependencies using apt-get auto-remove (or smth like that in another package manager) - but be careful here, check the packages list which are going to be removed. There accidentally might be some important things, you can tell that you still need with explicit install command. Please not that removing the package leaves it's configuration files. If you want to remove them as well you should purge the package. That was a brief introduction in a concept of software packages :) Yup, I know how packages are managed, and usually I do that. aptitude remove or purge.. But somehow I have not done that with kernel packages. I do not want to command aptitude purge kernel ;D Kernels are different, as there are various versions, and I just never want to live without *a* kernel. -- http://www.iki.fi/jarif/ You're currently going through a difficult transition period called Life. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

Debian packages are generally designed to remove all files that were installed when the package is removed. There is a difference between 'aptitude remove package' and 'aptitude purge package', though. The first removes all files of the package, except configuration files, the second removes all files of the package including configuration files. The kernel is somewhat special in that the installation also touches the configuration belonging to grub, ie. /boot/grub/menu.lst Normally, removing of the kernel package with aptitude will automagically update that file for you (unless you have changed your configuration from the default values). As far as files are concerned that belong to the kernel, but were created by you (or a script you ran), I don't know. I guess it would be your responsibility to take care of files that you have created, though ;-( I'm just trying to get some input from more experienced users before 'giving it a try'; eventually, I *will* do that, and follow with any questions or problems I may face. IMHE Debian's package system is rather robust and it is usually a severe fault of the user, if something goes horribly wrong (like ignoring all warnings and still continuing) PLUS that likelihood is rather small. I was just trying to point that out. NB: You should have some good backups of your system, so in the unlikely case that something goes wrong you could easily restore your system to the previous state (or investigate the difference to the previous state). -- Johannes Three nations have not officially adopted the International System of Units as their primary or sole system of measurement: Burma, Liberia, and the United States. http://en.wikipedia.org/wiki/Si_units -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of unsubscribe.

What is the Debian way of Good question. I wish I could tell you just dpkg -l linux-image\* and aptitude purge the kernels you don't like, but indeed in my experience this tends to leave some cruft around (e.g. linux-headers, maybe some modules compiled with module-assistant, ...). What I do is:\ - dpkg -l linux-image\* to see which kernels I have installed and I want to remove. - ls /boot to have a second opinion - aptitude purge linux-image-vers - dpkg -l '*vers*' | grep '^i' to see the packages whose name includes that kernel version and are still installed. E.g. dpkg -l '*2.6.26-1* | grep '^i' - aptitude purge them. Before purging them, you may think a bit about it and if you think they really should have been removed automatically, then use `reportbug' accordingly.
