10.10 kernel update breaks

[futurefx]

I can update everything in 10.10 but if i try to update kernel then synaptic shows: E: linux-image-2.6.35-22-generic: subprocess installed post-installation script returned error exit status 2

UCK log is useless currently because it wont indicate anything.

For reference, here's what you get when you run the kernel upgrade in a terminal started from UCK:

So essentially what's happening is that the update-grub command is aborting because it cannot determine the root file system.

As a workaround you can (temporarily) move the /etc/kernel/postinst.d/zz-update-grub procedure someplace else while updating the kernel from a terminal started from UCK (don't forget to restore it afterwards!) - this will make the kernel upgrade succeed (and on the live system grub is not used anyway - so configuring it doesn't really make sense in UCK).

I've no idea yet how to fix the issue permanently, though...

Still failure, it is impossible to update kernel. Why it worked on Lucid?

Looks like my 10.10 custom iso is doomed because UCK only is best that creates 100% accurate iso, i have tested others like reconstructor but those only creates mess. Is there ever hope to edit 10.10 correctly?.

OffTopic but sad that Ubuntu do not release updated iso files for releases monthly at least then i could just edit iso without upgrading.

? where, you mean 2.3.4? i have all UCK builds stopped because of bug.

it's on svn

[futurefx (force)]

too bad i do not have skills to make deb so i just wait 2.3.4 deb, but thanks a lot for fixing this horrible bug.

[Fabrizio Balliano (fabrizio-balliano)]

fix released with 2.4.0

I still have the problem updating the kernel with UCK 2.4.3 & Ubuntu 10.10 incl. all updates...

 Errors were encountered while processing:
 linux-image-2.6.35-22-generic
 linux-image-2.6.35-27-generic

E: Sub-process /usr/bin/dpkg returned an error code (1)

It's not neccessary to move "/etc/kernel/postinst.d/zz-update-grub".

It's sufficient to "chmod -x" them.
