Unhappy Ksplice


Hi Guys,
I have a new installation of Ubuntu 16.04 and I had installed previously on a 14.04 KSplice (http://www.ksplice.com/), without any issues.

The problem is after installing 16.04 and subsequently trying to install Ksplice it fails with no errors and no indication of failures, just simply refuses to proceed with installation.

I've tried the usual:
Reboot to fresh start and fresh install
apt-get update and install

According to Oracle KSplice for Ubuntu is open source and there are no pre-requisites.

Is anybody experiencing similar issues?

Cheers

I was keeping an eye on the development of ksplice back when it first emerged - when it was truely open source.
Then Oracle acquired it and tried to force everyone to a subscription model.
About the same time I was looking at OpenSolaris (for DTrace basically) - so Oracle bought Sun and killed OpenSolaris and sued the world re java.
Do we see a pattern here ?.

I have no love for Oracle, so even though I use Fedora I've never attempted to install ksplice. There is competing technology(s) being slowly merged into the kernel - I am waiting for that to mature.
If I get bored I may find a sacrificial lamb and set up a ksplice F23 machine and see if it suffers likewise to yours.

Hi
Thanks for the reply. I'm particularly annoyed with Oracle approach to the market as well. In this case I've run KSplice for the last couple of years (on Ubuntu) without any issues and I am more than happy with it, it's rock solid and quite beneficial as no reboot whatsoever it's required. In terms of backup there are no issues there, the new machine is working as it should and there are no data lost. It is just that now I have to apply kernel patches manually and REBOOT. I have not seen any similar technology, please share if you do not of any.
I highly recommend you to give it a shot (Ubuntu doesn't require payment) and is so simple and effective that you really understand the potential and why Oracle got it. Please bare in mind that 14.04 works fine but I'm having issues with 16.04

Cheers

Hi There
Thanks for the quick reply and I can report that the following command solve the installation problem.

sudo dpkg -i ksplice-uptrack.deb

I am not sure what is the root cause of the issue but this start the installation. I sort of questioning the new Ubuntu Software Update program as when I bypass it everything seems to work smoothly.

Anyhow hope it helps

Cheers

So you saved the download to disk rather than the recommended "Open with Software Centre" which would have installed automagically.
No big deal, the manual install is natural after that.

I'll still test a "throw-away" Fedora server sometime - maybe while watching the Giro.

True natural evolution there for installation... but first you have to suspect of the other installer... after the war everybody is a general.

Not sure about KSplice for Fedora being free, better check it out. I guess a good old VBox VM with Ubuntu will get you up and running in no time, but hey that's just me.
