Upgrading versions issue

Continuing a bit from above, I managed to get some systems to upgrade from Ubuntu 14 to 16.

Now, after that's done, the systems aren't able to do any subsequent upgrades.

I know this is not the latest version of the kernel on my "patching server":

root@FOO:/etc/apt# apt-get install linux-generic-lts-xenial
Reading package lists... Done
Building dependency tree
Reading state information... Done
linux-generic-lts-xenial is already the newest version (4.4.0.142.148).
The following package was automatically installed and is no longer required:
  libio-string-perl
Use 'apt autoremove' to remove it.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
root@FOO:/etc/apt#

I've done a apt-get update to make sure I'm pulling down any new lists of packages. An apt-get upgrade after that turns up nothing to update, which is definitely not right if everything is working.

I'm going to keep troubleshooting and adding information here as I come up with anything that might be valuable.

  • fyi: the linked page talks about upgrading 14.04 LTS to 16.04 LTS. Canonical/Ubuntu do have releases that are yy in format, eg. Ubuntu Core 16 for IoT, the more generic releases have yy.mm format releases as they have more than a single release per year. – guiverc Mar 22 '19 at 21:11
  • I'll keep reviewing. I have my own local repo server and it worked fine to do the upgrade from 14 to 16. None of the suggestions have worked so far, so I'll keep digging. – Marco Shaw Mar 25 '19 at 16:28
  • I just noticed that I have a "Hash Sum mismatch" in my apt-get update output for "xenial-updates/main amd64 Packages". Something must have missed up during the v14->v16 OS upgrade. – Marco Shaw Mar 25 '19 at 17:25
