recently installed Xubuntu, and upgraded to 14.04 earlier today. When I use Software Updater to search for updates it tells me there are no updates available. Here's what I did in terminal:

sudo -i
apt-get update
atp-get dist-upgrade (no problems so far)

restarted laptop

sudo -i   
update-manager -d

At this point I get this warning:

root:estimate_kernel_size_in_boot() returned '0'?

It then continues and opens Software Updater, which tells me the system is fully up to date. How do I fix this?

EDIT: To clarify, I'm using version 14.04 right now, I'm trying to upgrade to version 14.10, and then to 15.04

  • If you upgraded earlier today, why do expect there to be updates? Did apt-get update download the package lists alright, or were there errors? – Nephente Sep 22 '15 at 16:26
  • I upgraded to version 14.04. So Im looking for 14.10, so I can then upgrade to 15.04. – Roland Sep 22 '15 at 16:27
  • 14.10 is no longer supported, you won't be able to upgrade to it. – mikewhatever Sep 22 '15 at 16:33
  • That still doesn't explain why It doesn't show any updates. The latest version is 15.04, shouldn't I be able to update to that If 14.10 is no longer an option? – Roland Sep 22 '15 at 16:49
  • @Roland have you tried the second answer there? http://askubuntu.com/a/125646/158442 – muru Sep 23 '15 at 00:18
  • @muru yes, I was given a message telling me I didn't have permission to do that. I started another question asking about it but no one was able to help me so I just completely reinstalled ubuntu and everything works fine now – Roland Sep 23 '15 at 15:39

Go into System Settings -> Software & Updates -> and navigate to the tab where it asks you if you want all versions of Ubuntu or just stable ones then change it to all, and then do a sudo update-manager -d

  • Nothing i try to change in software & updates changes, check boxes flash a blue check then disappear, etc. but the revert option pops up after i do something. When closing it I get a message saying the information about available software is out of date, then i get an error saying I am not allowed to perform this action.
