What package to fix to prevent kernel upgrade was created by aike
Hi!
What packages I have to fix (stay not upgradeable), to prevent there upgrades?
First time i installed LinuxCNC, then make upgrade and new kernel installed.
After that i could not start LinuxCNC (rtai).
I reinstalled again and fix ONLY kernel-image-*-rtai.
What else I have to fix?

In 8.04 open the Synaptic Package Manager. Go to Settings, Repositories, Updates and select Never for Release Upgrade.

Doesn't that just stop EMC upgrades or Ubuntu distribution upgrades?
I believe he wants it so kernal image upgrades don't stop EMC fro working.
I'm sure it stops working because of re writing the default-starting kernal image.
Do we have instructions in the wiki on how to fix grub after an kernal image upgrade.
I would also suggest setting up grub to display the available kernal images, then you can always pick the right one.

The package needed to be uninstalled is linux-image-generic
this is a meta package, uninstalling it won't uninstall any kernel.
The metapackage is always made to depends on new kernel images, so that the system is up to date.
On a regular emc2 install (starting from the LiveCD), this package is not installed.
After uninstalling it, one still needs to fix the boot order in /boot/grub/menu.lst (there are loads of instructions how to do it).
Otoh, the suggestion from BJT is very good:
kernel updates are installed as new packages (with dependencies from linux-image-generic). Apt only installs new packages if run with dist-upgrade as the option, apt-get upgrade won't install new packages.
Uncommenting Release Upgrade will probably prevent new kernel images from beeing installed.

Alex

After that all updates and upgrades not install any new kernel image.
1. This steps not stored or menthioned in any places. Please include it in in wiki pages.
2. What packeges (linux-image, linux-header, linux-backports ...) i have to fix OR only ONE package - linux-image-*-rtai?
I wanted to know only this.
I instelled LiveCD, then (as usual) type: sudo aptitude update. A lot of updates stored in my cache. Then i type: sudo aptitude safe-upgrade (or dist-upgrade). So as current kernel is older, then new for ubuntu-8.04, the new kernel installed. And it becomes bootable.The package needed to be uninstalled is linux-image-generic
