When executing apt upgrade (after running update first), is displays information that packages linux-generic linux-headers-generic linux-image-generic linux-libc-dev are going to be downgraded.

Should I proceed, or something is wrong with dependencies?

My current dist is 16.10, with 4.8.0-40-generic #43-Ubuntu SMP kernel.

Here's full command output:

[~]$ sudo apt upgrade

  • Did you add any PPA? – Pilot6 Mar 6 '17 at 10:39
  • Yes, I have around 20 ppa's, had no such problem previously. Maybe should I simply not upgrade yet? – PeterM Mar 6 '17 at 10:46

    So the problem is with some of the added PPA. You need to look int them and find out what is the dependency problem. It is not a good idea to add many PPA when you have no idea what is there. – Pilot6 Mar 6 '17 at 10:48

    The package 4.8.0-40 has been deleted from the repository. I don't know why. Presumably a new kernel will be pushed out in the next few days. – bwduncan Mar 7 '17 at 13:24

    Thanks @bwduncan, You were right, new kernel just arrived. Maybe previous had some issues. – PeterM Mar 8 '17 at 10:56

The linux-image-4.8.0-40-generic package and related packages were deleted from the repository. I don't know why. A new linux-image-4.8.0-41-generic has appeared and the upgrade now goes smooothly.
