I am having some difficulty with recent software updates and this is not the first time.

By pressing the shift key on startup I can (usually) get the grub menu but when I choose "advanced options" it only shows 2 options: 3.13.0-24 and 3.13.0-24 (recovery mode) whereas I understood it should show previous kernel versions.

I already stick to only LTS versions of Ubuntu. What is a safe way to accept updates in future please? How can I install only the most tested updates? I would like to be able to easily roll them back if they cause problems. In other words I am looking for the Linux equivalent of making a Windows system restore point. Maybe I should never accept updates but wait until the next LTS version and then upgrade?

  • Thanks for your quick comment but the top answer in the possible duplicate says "Simply boot an older kernel" but that does not appear to be simple as I do not have the option on my grub menu as far as I can see. – user314847 Aug 12 '14 at 09:30
  • Have you tried searching how to do that? Essentially, there is no feature for roll back currently. – Tim Aug 12 '14 at 09:31

    Which channels are you using to get updates? In your sources.list, do you have proposed enabled? You can install an older kernel version if it is still available in the repository. – muru Aug 12 '14 at 10:11
  • @Tim: OK thanks as I suspected from other answers here there still is not a straightforward built in rollback feature. So now that is confirmed I can stop looking for one. I have not answered my own question as, being new here, I am not sure whether Tim will get kudos if he writes it as an answer. If there is some proposed feature it would be good to have a link in the answer if there is some kind of voting option to support it. – user314847 Aug 12 '14 at 10:33
  • @Muru: I am not sure how to check sources.list but I was pretty surprised when I looked at "Install updates from" to see "Unsupported updates" ticked. So I have unticked that thanks. – user314847 Aug 12 '14 at 10:36
  • I suppose that should be enough for now. Considering how strict you were going to be, you could enable just -security and -updates. For future reference: grep proposed /etc/apt/sources.list. – muru Aug 12 '14 at 11:22
