In the distro I'm most familiar with -- ALTLinux, a command like apt-get install kernel-image-std-def#3.0.... would install another kernel, and update the initramfs and the bootloader config accordingly; an even better command would be the specific update-kernel, which would also install the accompanying kernel modules for the new version of the kernel (the ones that are installed in the running system, so that the support for the hardware of this system is not lost in the case of the new kernel). (A short manual on this topic for ALT (in Russian).)Now I want to upgrade the kernel in my Ubuntu 12.04 system on a Toshiba AC100 (ARM). What would be the command in Ubuntu to install the new kernel, so that all the required things are done: initramfs is generated, the bootloader is updated, and no required module is lost?I'm especially interested in a command that would ensure that everything is done correctly, because I don't understand the peculiar boot process on this computer very well.
The command to upgrade to a new kernel from Ubuntu repositories
ubuntu;apt;linux kernel;upgrade;kernel modules
Simply installing the new kernel package will handle everything for you. Most of the time, you want to go ahead and upgrade all of your packages, as it will mostly include bug fixes and security updates:apt-get updateapt-get upgradeIf you call install on a package that is already installed, it will be upgraded if an upgrade is available.apt-get updateapt-get install linux-image-ac100
