[15.10 > 16.04] Am I on the right version?

[grimpressive]

Hi there,
I just made a dist-upgrade of my machine towards 16.04 available in my updater via GUI (official, not dev version).

The update process has gone quite ok but in "Installing packages" it returned an error "subprocess installed post-installation script returned error exit status 1".
After pressing the close button it said "Ok man, you're now on 16.04."

But I'm a bit unsure.

tailing /var/log/dist-upgrade/main.log gives me:


2016-04-22 11:01:19,305 DEBUG running apport_pkgfailure() mysql-server-5.7: subprocess installed post-installation script returned error exit status 12016-04-22 11:01:19,309 ERROR got an error from dpkg for pkg: 'mysql-server-5.7': 'subprocess installed post-installation script returned error exit status 1'

Any run of apt-get upgrade tells me nothing else to do, lsb_release -a says:

No LSB modules are available.Distributor ID: Ubuntu
Description: Ubuntu 16.04 LTS
Release: 16.04
Codename: xenial


So it should be ok.
System is running so I should be happy... BUT as an example, afaik the new program "Ubuntu Software" should replace the older one, but if I type "Software" in my launcher I got:

Ubuntu Software Center (15.10?)
Software and Updates (15.10?)
Software Updater (should be ok)
Ubuntu Software (16.04?)
Edit: striked-out known bug @see http://ubuntuforums.org/showthread.php?t=2321281


So the question is, am I running on a "clean" 16.04 or something went bad in the final dist-upgrade process and I'm typing on a human/alien hybrid Ubuntu distro? :)

Tl;Dr:

Is there any way to "verify" the integrity of my installed distro?

Thanks in advance any suggestion would be appreciated.

Well, you have the correct lsb_release file. And I am sure that the login screen is branded "Ubuntu 16.04 LTS." Do you have the correct Linux kernel?


unname -a

You should have this


graham@sdb7-Dev:~$ uname -a
Linux sdb7-Dev 4.4.0-21-generic #37-Ubuntu SMP Mon Apr 18 18:33:37 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux


Next question. Do you have the xenial repository URLs in your sources list file? Open Gedit to /etc/apt/source.list. The URLs should have "xenial" & not "wily." Run again


sudo apt update
sudo apt upgrade
sudo apt full-upgrade

If we only have xenial repositories we will only get 16.04 (xenial) code.

Yep, then I think is some sort of false alarm because uname shows correct kernel and sources for aptitude are all pointing to xenial.

Dunno why it stopped halfway without saying "Ok, despite of minor errors I installed correctly the whole thing", I'm still afraid some post-install procedure didn't complete properly.
But it all says I'm on a valid 16.04 LTS.

Ty for the feedback.
